Wheel of Fortune timeline (network)

An incomplete timeline for the daytime version of Wheel of Fortune. For the nighttime version, see Wheel of Fortune timeline (syndicated).

(Due to NBC's practice at the time, many episodes from 1975-80 were destroyed or recorded over. Further, Game Show Network {henceforth referred to as GSN} has only shown three daytime episodes {not including Wheel 2000}. As such, this timeline will be much less detailed than the nighttime one.)

Pilots (1973-74)
September 1973 :
 * At some point in September, the Shopper's Bazaar pilot is taped for NBC by request of Lin Bolen to Merv Griffin. It is markedly different from the eventual series in various ways, including:
 * 1) The show is hosted by Chuck Woolery, with announcer Mike Lawrence.
 * 2) The Wheel is vertical and mechanical, with no Bankrupts and only one Lose A Turn. Unique spaces on this Wheel are $0, Free Vowel, and Your Own Clue.
 * 3) Your Own Clue involves a rotary telephone where Lawrence dispenses a clue for the contestant who spins it. The clues get more detailed the more it is hit, but only for that player.
 * 4) Top dollar is $500 for Rounds 1-2 and $1,000 for Round 3 onward.
 * 5) The bonus round, called the "Shopper's Special", is the name of the prize the contestant is playing for. The winner is shown all vowels in the puzzle, then has 30 seconds to give consonants to fill in the solution.
 * This pilot is held by GSN. Despite airing numerous pilots over the years, the network has (so far) not shown Shopper's Bazaar.

September 1974 :
 * At some point in September, the second and third pilots (now called Wheel of Fortune) are taped in Los Angeles for NBC. Changes include:
 * 1) Edd Byrnes and Charlie O'Donnell replace Woolery and Lawrence.
 * 2) The show's theme song is changed to "Give It One" by Maynard Ferguson. It is unknown what music was used on the 1973 pilot.
 * 3) The Wheel is now horizontal, with much larger wedges plus the introduction of Bankrupt and Buy A Vowel.
 * 4) The Wheel's top dollar for each round is presumably increased to $500 for Rounds 1-2, $750 for Round 3, and $1,000 thereafter. The minimum value is $50.
 * 5) The puzzle board is now gray with 39 trilons on three rows and a single light border. The trilons show green sparkles for unused spaces, a solid white for unrevealed letters, and black letters on a white background. Once a contestant solves the puzzle, all letters light up and the unrevealed ones are turned around to a portion of "Give It One".
 * 6) Contestants now purchase from a "showcase" of prizes located behind the puzzle board, which moves away so the player can shop. Both pilots use the same prizes, with their names and values scrolling on-screen; a "SOLD" tag marks prizes already purchased.
 * While the puzzle board is designed to be mechanical, this element is not completed by the time of taping. Susan Stafford is hired to turn the letters.
 * Edd is drunk during these pilots, as he recounts in his autobiography Kookie No More. On the first taping, he makes faces at the camera; on the second, he makes noises as the Wheel spins. He also bullies at least one contestant into spinning again, yelling "No! You only have $300! You can't solve yet!"
 * When shown to test audiences, the response is that the new set is too busy and Byrnes does not fit. Bolen insists the show be picked up anyway, and her bosses agree on one condition – Chuck is host, not Edd. (It is rumored that Edd was caught reciting his vowels backstage by Merv.)
 * Both pilots are known to exist; clips from one of them were shown during the nighttime version's ceremonial 3,000th show (November 20, 1998), which includes contestant Roseanne solving PRINCESS ANNE for $825.

Season 1 (1975)
January 1975 :
 * Wheel of Fortune debuts on January 6, 1975, replacing Jeopardy! as per contract but in the 10:30 AM slot formerly held by Winning Streak. Aside from Chuck hosting, there are only four changes:
 * 1) The show's theme song is changed to "Big Wheels" by Alan Thicke, who also supplies the show's other music cues.
 * 2) The Wheel's values are moved around a bit, with the minimum now $25. $50 and $75 spaces are also present.
 * 3) The puzzle board trilons now turn clockwise instead of counterclockwise.
 * 4) The single shopping "showcase" behind the puzzle board is changed to three platforms at the back of center stage. The first platform is used after Round 1, the second after Round 2, and the third after Round 3; in the event of subsequent rounds, the process begins again at the first platform.
 * January 6 has the first discarded puzzle. As mentioned by Charlie during the credits, the contestant who won it was credited with her winnings, a new puzzle was substituted, and the program edited.
 * The January 6 show is known to exist, as clips of it were used in the show's E! True Hollywood Story.

February 1975 :

March 1975 :
 * On March 17, in honor of St. Patrick's Day, Wheel and NBC's other daytime games (then Blank Check, Celebrity Sweepstakes, High Rollers, The Hollywood Squares, and Jackpot!) participate in the "Shamrock Sweepstakes". Players from these games answer questions about Ireland and Irish(-American) people, with a top prize of $100,000.

April 1975 :

May 1975 :

June 1975 :

July 1975 :

August 1975 :

Season 2 (1975-76)
September 1975 :
 * By about this point, Milton-Bradley releases two board game adaptations; these are the only ones to be released in the 1970s, and the only ones to use the shopping element (represented by a deck of 20 prize cards ranging in value from $100-$3,000). This home game confirms several aspects about the game at that point, including:
 * The categories that were in use at the time: Event, Fictional Character, Landmark, Person, Phrase, Place, Thing, and Title.
 * The green $75 becomes a second $500, the sole $25 becomes $300, the red $50 becomes $150, the yellow $75 becomes $200, and the blue $50 becomes $100. The minimum value is now $100.
 * The shopping round begins allowing contestants to put their winnings on a gift certificate, in addition to the existing "on account" option. From this point until the removal of the shopping rounds, most contestants choose the gift certificate.
 * Any instance of punctuation is ignored (i.e., FISHERMANS WHARF instead of FISHERMAN'S WHARF).
 * Buy A Vowel is still present on the Wheel.

October 1975 :

November 1975 :

December 1975 :
 * On December 1, in the wake of The Price Is Right expanding to 60 minutes a month earlier (November 3), Wheel expands to 11:30 AM; High Rollers, which normally occupies the 11:00 slot, does not air during this period. Changes made for the hour-long format include:
 * Three contestants play three rounds each in the first half-hour, apparently with $500, $1,000 and $1,500 as the top dollar values. A second set of contestants is introduced in the second half-hour, also playing three rounds for these amounts.
 * The winners of each half-hour segment play a head-to-head round with $2,000 as the top value. Also, one wedge is placed on the Wheel which corresponds to a prize. It is believed that, if a contestant hit Bankrupt while holding a prize wedge, it was placed back on the Wheel.
 * The winner of the head-to-head round is believed to have played a bonus round with the same rules as the Star Bonus round, which is described in further detail below.

January 1976 :
 * On January 19, Wheel returns to a half-hour, now at 11:00 AM. High Rollers returns at 10:30. All of the new elements added in the hour-long format are retired, although the $2,000 wedge returns in 1979 and the concept of a prize wedge is reintroduced around 1983.

February 1976 :

March 1976 :

April 1976 :

May 1976 :

June 1976 :
 * On June 3, 4, or 6, contestant Linda sets a single-round winnings record of $8,325.
 * By June 7 (#368), the Wheel has gone through several changes:
 * 1) Buy A Vowel and the second Lose A Turn are removed.
 * 2) Bankrupt, Lose A Turn, and Free Spin adopt their normal appearances.
 * 3) Top dollar in Rounds 2 and 3 are increased to $1,000 and $1,500, respectively. These may have held over from the hour-long episodes.
 * By June 7, the contestant score displays are changed to white. Previously, they had been the same color as the respective contestant's arrow.
 * As of June 7, there is still no sound effect for hitting Bankrupt.
 * As of June 7, champions still remain on for up to five days.
 * As of June 7, the original category displays are still in use. They are very similar to the style introduced in 1985, albeit shown on-screen sporadically.
 * On June 7, there is a noticeable layer of dust on top of the contestant arrows.
 * Several other events happen on June 7:
 * Charlie's introduction of Chuck is "Now, let's meet the host of Wheel of Fortune, Chuck Woolery!"
 * During Round 1, a buzzer sounds on a correct letter.
 * With only vowels remaining, contestant Gerry mis-solves the Round 1 puzzle KILL THE UMPIRE as KILL THE VAMPIRE.
 * Following Round 1, Chuck mentions getting letters from people who don't like seeing him hug contestants. He responds by saying "I like to hug folks. I'm a hugger. A lot of people are handshakers; I'm a hugger. And one more thing: If you were here, I'd hug ya too!"
 * During Round 2, contestant Lee loses a then-very high total of $2,750 to a Bankrupt.
 * After Lee solves the Round 3 puzzle (NORMAN ROCKWELL) for $800, Chuck has her spin one more time before announcing the winner. She hits $1,500.
 * Returning champion Linda sets a new half-hour total winnings record of $23,200.
 * The closing segment has Chuck and Susan saying goodbye as the camera zooms out to show the Wheel spinning. This effect was dropped by 1978, but returned in 1980.
 * The June 7 show is the earliest Wheel episode, one of only three daytime episodes, and the only episode hosted by Chuck to be aired by GSN; the network reruns it in 2007 as part of a special string of repeats following Merv Griffin's death. As per the network's standard at the time, the ticket and fee plugs are cut out and the credits are crunched.

July 1976 :

August 1976 :

Season 3 (1976-77)
September 1976 :
 * By this point, and probably much earlier, Chuck and Susan play Celebrity Sweepstakes for home viewers on the last day of a play-by-phone week (the only non-soap opera personalities to do so). The winning home players get $75,000 for first place, $20,000 for second, and $5,000 for third.

 * By March 18, the Round 1 Wheel layout changes a bit: The blue $100 near Free Spin becomes $400, the blue $100 next to Lose A Turn becomes $400, the orange $100 near Bankrupt becomes $500, and the blue $100 next to Bankrupt becomes $350. The Wheel's "face value" (all the wedge values added together) is increased from $4,875 to $6,125.
 * By March 18, the score displays are extended to show five digits and a dollar sign.
 * By March 18, the category displays are changed to a thin, computer-esque font in various colors.
 * On an episode after the above changes, contestant Pat puts $15 "on account" after Round 1. Later in the same episode, contestant Barbara purchases a 1978 Camaro for $6,125.
 * At some point between March 18 and April 6, the Star Bonus token is introduced; the token is on the red $100 next to Free Spin during Rounds 1-2 and $150 during Round 3. The token cannot be lost to Bankrupt nor forfeited by failing to solve the round's puzzle, but is removed from the Wheel following Round 3 to play a fourth round.

April 1978 :
 * On April 5, contestant Karen retires with over $16,000.
 * Veteran game show contestant Scott Hostetler plays on April 6 and 7.
 * By April 6, the curtain's lights are removed.
 * By April 6, and probably much earlier, Susan begins entering through the center of the curtain. Previously, she entered from Chuck's left and helped introduce the contestants.
 * By April 6, and probably much earlier (one recollection claims it was in 1977), a sliding whistle is added for when Bankrupt is hit.
 * By April 6, the blue $400 near Free Spin is turned red, presumably because it sat next to a blue $300.
 * On April 6, the first commercial outro is a closeup of the Star Bonus token, zooming out to a full shot of the Wheel.
 * By April 6, Nyesta and Augustus begin providing the wardrobe for Susan and Chuck, respectively.

 * As of April 7, puzzles have started using hyphens (in this case, in the Round 1 answer LOVEY-DOVEY).
 * During Round 1, a bell sounds on an incorrect letter.
 * Contestant Peggy sweeps the game.
 * The Star Bonus is played, which results in the contestant interviews being edited down considerably. The prizes are a trip to Las Vegas (Easy; $675), a sterling-silver tea set (Medium; $2,303), a diamond pendant (Hard; $4,060), and a Porsche 924 (Difficult; $13,586). Scott plays the Difficult puzzle, and fails to solve PABLO PICASSO. There are at least two other known instances of the Star Bonus being played in its short life.
 * Charlie's closing spiel about the prizes is "covered" by a different voice saying "Additional prizes furnished by Jockey's Club Resort, Bob Smith Porsche Audi."
 * On April 24, the show moves to 11:30 AM.

 * March 27 is the earliest known appearance of Quotation and Occupation.
 * By March 27, Roselon Industries begins providing Susan's wardrobe.
 * On March 27, the first three spins of Round 2 are all Bankrupt, to which Chuck responds by beginning his Round 2 intro spiel again. It takes a total of seven spins before a correct letter call, and another 11 before FOURSCORE AND SEVEN YEARS AGO is solved.
 * Overall, the contestants in this round end up hitting Bankrupt six times, which may be a one-round record.
 * In the same round, Susan turns the V too hard, causing the plastic letter sheet to slide about halfway off the trilon.
 * In the same round, for some odd reason, contestant Anita prefaces her letter picks with "I'd like to buy a..."
 * On March 27, Chuck's Final Spin lands on Bankrupt.

 * By December 4, a new music cue is introduced for use when going to commercial.
 * By December 31, holiday decorations are added to the curtain as well.
 * By December 31, and likely much earlier, the returning-champion limit is decreased to three days.
 * By December 31, the aforementioned commercial outro cue is replaced by an electric-guitar music cue.
 * December 31 has a few notable events:
 * During Round 2, the puzzle solve cue accidentally plays for a second instead of the "only vowels remain" beep (which is itself played a second later). The contestant solves the puzzle, and the cue begins playing from the point it was cut off.
 * The December 4 commercial cue is used for the prize descriptions after Round 3.
 * In Round 4, the puzzle intro cue is played over a shot of Chuck before quickly switching to the puzzle board.
 * Contestant Allan retires with $15,425, which Chuck mistakenly refers to as $1,425 until he is corrected from offstage. (The total champion winnings/"on account" display simply removes the dollar sign; on June 7, 1976, the display was simply left blank.)
 * For the closing segment, Chuck and Susan promote their appearance the next day during the Tournament of Roses pre-parade.
 * "Auld Lang Syne" is played from Chuck and Susan's sign-off through the end of the credits.

January 1980 :
 * Wheel does not air on January 1 due to the aforementioned Tournament of Roses parade.

February 1980 :

March 1980 :
 * On March 15, Pat Sajak hosts a pilot for Goodson-Todman Productions and NBC called Puzzlers. It does not sell, likely due to the below.
 * On March 17, contestant Becky puts money "on account". According to comments the next day, it works to her advantage.
 * March 18 has several events:
 * Contestant Charlene gets two Free Spins in a row during Round 1.
 * During Round 1, Chuck forgets on two separate occasions to ask if a contestant wants to use their Free Spin following an incorrect letter call.
 * Contestant Les' microphone falls off during Round 2. He quickly retrieves it, and it is reattached during the commercial break.

 * The first known instance of a one-word puzzle, in this case Round 4's PORCUPINE.
 * Following Round 4, the camera suddenly shifts to the right as contestant Kevin selects his first prize.
 * Five rounds are played, an unusual event for the shopping era. Chuck refers to it as being the "first time in a long time", implying that it has happened before.
 * Rounds 4 and 5 are both Thing.
 * Chuck and Susan say goodbye to stage manager Rob Keith, who is listed as "Robin Kenner" in the credits and who Chuck mistakenly refers to as unit manager (the actual person holding that position at this point is Michael Koljan).
 * Chuck and Susan's signoff is quite different than usual: "I'm Chuck Woolery," "And I'm Susan Stafford." "See you all tomorrow, bye-bye everybody." "Bye-bye, God bless!"
 * By March 25, the commercial outro cue used on December 4, 1979 returns for all breaks.
 * By March 25, original producer John Rhineheart is replaced by Nancy Jones.

April 1980 :

May 1980 :
 * On May 6, a champion retires undefeated.
 * On May 7, in a rare occurrence, all three contestants are left-handed; one of them, Cathy, is from Paris. Also on this episode:
 * During Round 1, contestant Diane lands on Free Spin and, after receiving a token, tries to call an S. After her next spin, she is credited with the S, which is in the puzzle.
 * The Round 1 puzzle, APHRODISIAC, is believed to be the longest one-word puzzle up to this point.
 * Early in Round 2, the trilon containing the P in STOP LOOK AND LISTEN is accidentally lit up after T is called. The mistake is quickly corrected.
 * Rounds 1 and 3 are both Thing.
 * In Round 3, the contestants are shown turning their backs during the mid-round outro.
 * After the game, Chuck and Susan address rumors about the show's cancellation; while dispelling them, Susan notes that NBC's daytime schedule will be undergoing a few changes. Chuck replies with "In the meantime, we're gonna be doing this show until we get it right!"
 * By May 7, the show now uses both commercial cues: The December 4, 1979 cue after each round, and the electric-guitar cue for mid-round breaks.

June 1980 :
 * June 9 has several notable events:
 * During Round 2, contestant Heidi begins to call a Z during Round 2, but stops herself and calls a D instead. She is credited with the D, which is in the puzzle.
 * Rounds 2 and 4 are both Phrase.
 * Chuck's Final Spin hits Lose A Turn; his second attempt lands on $2,000.
 * Contestant Fred solves the Speed-Up puzzle SLY AS A FOX with SL_ _S _ ___ showing.
 * By June 9, the December 4, 1979 cue is again used for mid-round breaks (in this case, during Round 3). The electric-guitar cue is not used at all.
 * June 20 has several interesting events:
 * Chuck makes an odd comment to Susan after her entrance, saying she looks like "a little Swedish girl".
 * Charlie coughs briefly during the second prize plug, which Chuck brings up before Round 2.
 * A somewhat infamous moment after Round 1 where contestant Charlotte reluctantly says "[I'll] take the...candy dish.", to which Chuck talks with her and the purchase is discarded. Chuck then remarks after the prize plugs that the painting she bought was better than the other one the show had from the same artist, which was "seventeen lizards sucking on an orange".
 * The Bankrupt sound does not play when it is first landed on in Round 3.
 * The Round 3 puzzle is APRIL FOOLS' DAY, and there is no inlaid contestant shot during the shopping portion.
 * Rounds 2 and 4 are both Phrase.
 * Chuck's Final Spin lands on Bankrupt.
 * After the game, Chuck and Susan discuss the waiting period for prize delivery (90 days). When asked by Chuck, an offstage staffer says they're shipped "whenever we get around to it".
 * By June 20, the commercial outro cues are changed up again: The electric-guitar cue is used after Rounds 1 and 4 plus the break during Round 3; the December 4, 1979 cue is used after Rounds 2 and 3.
 * On June 20, NBC airs a promo detailing the new schedule to begin the following Monday. The promo includes a clip from Wheel of a female contestant right after solving CREPES SUZETTE (Things), and apparently screaming so loud Chuck is seen with his hand up to his ear.
 * Also on June 20, Vanna White appears as a contestant on The Price Is Right, her first television "role". Despite being called down fourth, she never gets out of Contestant's Row.

July 1980 :

 * Chuck's Final Spin lands on Bankrupt.
 * The Wheel does not spin during the credits. The camera shot is also zoomed out farther than usual.
 * By August 18, the commercial outro cues are changed up once again: The December 4, 1979 cue is used when going to commercial during and after Round 3.
 * Alex Trebek fills in for Chuck around this point, most likely the week of the 25th.

Season 7 (1980-81)
September 1980 :

October 1980 :

November 1980 :
 * November 3-6 (and possibly October 31 as well) features NBC game show hosts playing for members of the audience, who also determine what prizes to buy in the shopping rounds. Each match pits the host against two contestants who play normally. Wink Martindale and Jim Perry are among the participants, and it is rumored that Art Fleming also played.
 * Bill Cullen plays on November 5, and based on comments the next day ("He blitzed everybody."), he sweeps the main game.
 * On November 6, Tom Kennedy plays for Art and wins $1,400.
 * November 6 is the earliest known appearance of Landmark.
 * By November 6, the electric-guitar commercial cue is moved to the mid-show consolation prize plug (although it is barely audible on November 6). The December 4, 1979 cue is now the only one used for commercial breaks.
 * As of November 6, the contestant score displays are still the same color as they were from at least June 1976.
 * November 7 begins the show's first Armed Forces "Week", plugged as such despite beginning on a Friday.
 * Immediately following the Armed Forces episodes is "Celebrity Week On The Town".
 * The returning champion from November 6 probably returns on the 24th.

December 1980 :
 * By December 18, and probably for the entire month, the set is again decorated for Christmas. Unlike 1979, the curtain has a wreath on it and the foliage behind the contestants is thicker.
 * By December 18, the contestant score displays are tinted yellow.
 * December 18 has several notable events:
 * Chuck's cord gets caught on the nearby car as he makes his entrance.
 * The shopping cue begins in the wrong place after Round 2, then starts again from the beginning.
 * After Round 3, the camera fails to switch to the first prize until Jack is halfway through describing it.
 * Contestant Joyce retires with $17,550.
 * As of December 18, the December 4, 1979 cue is still the only one used for commercial breaks.
 * By December 24, the contestant score displays return to their normal color.
 * By December 24, the commercial cues are changed up once again: For the first time in over a year, the show's theme is used when going to commercial during Round 1 and after Round 3; the December 4, 1979 cue is used after Round 2, while the electric-guitar cue remains at the mid-show consolation prize plug.
 * December 24 also has some events of note:
 * Contestant Vicki's first spin runs into some kind of error that is not explained clearly on-air, primarily since the error and resolution happen while the camera is focused on the puzzle board; the Wheel is reset, and she spins again.
 * There is a commercial break during Round 1, the earliest known instance of this happening.
 * Chuck mistakenly says that the top dollar for Round 2 is $2,000.
 * The earliest known instance of a puzzle containing two punctuation marks, in this case Round 2's SLEIGHBELLS RING ARE YOU LIST'NIN' (Quotation). It is also very large for the era, using all but nine trilons, and is solved by contestant Linda for a then-massive $6,700.
 * After Linda buys a $6,168 Mazda following Round 2, Susan is seen closing the driver's-side door from the inside. Once Jack gets to the car plug, Susan drives it around to stop in front of the prize displays, honks the horn, and gets out.
 * Rounds 3 and 4 are both Thing.
 * A buzzer fails to sound on an incorrect letter during Round 4.
 * No music is played during the commercial outro after Round 4, although it fades to black before it can do so.

January 1981 :

February 1981 :

March 1981 :

April 1981 :
 * By April 21, the electric-guitar cue returns to use for all commercial breaks and the mid-show car plug.
 * Several events occur on April 21:
 * Jack's introduction of Chuck is "And now, let's meet your host: Chuck Woolery!"
 * Chuck mentions his habit of licking his finger before touching the Wheel, and that the producer (Nancy Jones?) replied by saying "You don't know where that Wheel's been!" His reply is simply that "I don't care where that Wheel's been!"
 * Contestant Virginia attempts to spin the Wheel during the Speed-Up round, but is stopped by Chuck before she can do so.
 * Later in the Speed-Up round, a buzzer fails to sound to end a turn. A few turns later, Susan turns the N too hard, causing the plastic letter sheet to slide about halfway off the trilon.
 * What is believed to be the lowest one-round score up to this point: $250.
 * Contestant Lori sweeps the game.
 * After the game, Chuck mentions that a couple of weeks ago, he had brought up the fact that the show has done over 1,600 episodes.
 * As of April 21, the $2,000 space is still red.
 * As of April 21, the Final Spin split-screen shot still has the puzzle on top and the players on the bottom.
 * As of April 21, there is still no regular bonus round.

May 1981 :

June 1981 :

July 1981 :

August 1981 :

Season 8 (1981-82)
September 1981 :
 * There is a Portland Week at some point in September, where contestants from that city are flown in to compete.
 * On an episode during Portland Week, contestant Linda prepares to solve the puzzle AIR TRAFFIC CONTROLLER before a voice (that of opponent Frank) tells her to spin again; she does so and hits Bankrupt, after which he solves for $1,800.
 * As of the Portland Week, the electric-guitar cue is still in use for at least one commercial break (a mid-round outro).

October 1981 :

November 1981 :

December 1981 :
 * The week of December 14 is Christmas Wish Week.
 * December 18 has several events:
 * After contestant Terry explains how he is a "househusband", Chuck replies that "I'll be a househusband on December 26".
 * During Round 2, two vowel calls (O and E) and their reveals on the board are done in complete silence, with no applause at any point.
 * An instrumental version of "Frosty the Snowman" plays during the Round 3 prize descriptions.
 * The earliest known instance of three puzzles in the same category: Rounds 2 and 4 are Thing, while the bonus round is Things.
 * After the game, Susan mentions the set changes to take effect the following Monday.
 * By December 18, the commercial break cues are changed up once again: The show's theme returns, used after Rounds 1 and 3 plus the mid-show catalog plug and after the bonus round; the December 4, 1979 cue also returns, used after Round 2.
 * By December 18, the current bonus round is in place; it is referred to this week as the "Christmas Wish Bonus".
 * As of December 18, shopping rounds are still done after the Speed-Up, even if the round begins as a Speed-Up.
 * The week of December 21 is Christmas in New York; much like the Portland Week, contestants are flown in from that city to compete. The opening for this week does not use the Wheel logo, instead showing Susan walking in a light New York shower.
 * On December 21, the set is overhauled:
 * 1) The various prize platforms are replaced by a single, large, three-sided turntable at center stage.
 * 2) The puzzle board is given a fourth row and another nine trilons, for a total of 48 (11 on the top and bottom rows, 13 in the middle two).
 * 3) The contestant area is changed to solid starbursts of the same color as the respective contestant's arrow. They continue to display the money put "on account" or total champion winnings.
 * By December 25, the December 4, 1979 cue is once again put to use for all commercial breaks and the mid-show plug for the airline which flew the players to California.
 * By December 25, the $2,000 space is changed from red to a yellowish color.
 * On at least December 25, Susan does not make her entrance through the curtain; rather, she walks over from next to the puzzle board as the turntable spins.
 * December 25 is Chuck's last show. Among the events that day:
 * Susan's entrance includes her blowing kisses to Chuck.
 * There is a commercial break during Round 1, which Chuck erroneously states as having never happened before; one such break occurred on December 24, 1980, and probably other times.
 * During Round 2, Chuck quips that one of the contestants (Betty?) is "the only person I've ever known to hit [Lose A Turn] seventeen times consecutively".
 * After recapping the scores and announcing the winner, Chuck thanks Susan for being such a confidant over the previous years; he then thanks several people, including John Rhineheart, Nancy Jones, Charlie O'Donnell, Jack Clark and Merv Griffin. Chuck follows this by admitting that leaving Wheel is "one of the most difficult things I've ever done".
 * No bonus round is played.
 * "We Wish You a Merry Christmas" is played during the fee plugs and credits.
 * During the credits, Jack mentions that due to a technical difficulty, "a third puzzle was discarded and the program edited".
 * Susan presents Chuck with a gift: A pair of goggles with wipers.
 * On December 28, Pat Sajak becomes the show's host. Oddly, on December 16-18 and 21-22, he appeared on Password Plus and was credited as being "from Wheel of Fortune".
 * The week of December 28 is a Teen Week. As with the previous week, the Wheel logo is not used in the opening. Instead, the graphics say "Teen Week on Wheel of Fortune", with the words "Teen Week" in quotation marks.
 * Pat's first episode has several notable instances:
 * Pat thanks Chuck for hosting the show and wishes him well, then jokes that he is leaving the show as well.
 * The contestant interviews are noticeably edited down, perhaps because of Pat's monologue.
 * The camera is zoomed too far back at the start of Round 1.
 * The commercial cues are changed up once again: The electric-guitar cue returns for use during Round 1, during the mid-show catalog plug, and after the bonus round; the December 4, 1979 cue (sounding slightly different) is used during Round 2 and after Round 3. An unknown cue is used following Round 2, as it only plays extremely briefly.
 * Susan turns the hyphen in Round 2 before it is lit up.
 * During Round 2, the camera zooms out from the $550 space while an incorrect letter is called.
 * Contestant Jay opts not to buy the $2,195 hot tub after Round 2 and instead purchases the other 10 prizes in that showcase with the remaining $849 placed on a gift certificate; the resulting prize copy runs a solid two minutes, and Pat remarks afterward about Jay not buying the hot tub.
 * The bonus round is played from the yellow contestant backdrop.
 * By December 28, the Final Spin rules are altered a bit: If the Speed-Up round is the entire round, it is played for a gift certificate (or, during this week, a savings bond).
 * By December 28, the Final Spin split-screen display is changed to have the puzzle board on the bottom.
 * As of December 28, the money graphic is still green and still zooms in.
 * As of December 28, Roselon Industries still provides Susan's wardrobe.
 * During Pat's first week, a contestant buys a vowel which is not in the puzzle and Pat tells the player to spin again. He is then told by Nancy Jones that the player has in fact lost their turn.
 * During Pat's first week, a contestant mis-solves the puzzle ABRAHAM LINCOLN as ABRAHAM BINCOLN.

January 1982 :
 * Claudia, the returning champion from Chuck's last episode, presumably returns on January 4.
 * It is believed that the practice of playing the bonus round in front of the puzzle board began on January 4; it was definitely in place before March 11.
 * At some point in January, the show holds a Hawaii week, as promoted by Pat during his week on Password Plus. Most likely, this was done identically to the Portland and New York weeks in 1981, by flying in contestants from Hawaii.

February 1982 :

March 1982 :
 * By March 11, the money graphic is changed to white and "springs" or "flips" toward the camera.
 * By March 11, the show's theme returns to use for all commercial breaks and the mid-show car/catalog plug.
 * By March 11, a timpani roll is added to the start of the bonus round. The Wheel of Fortune logo is projected onto the floor unless the contestant plays for a car, in which case the car is parked between the Wheel and the board. All of these aspects may have been introduced on January 4.
 * By March 11, the credits are slightly changed to show the Wheel spinning below Pat, Susan and the day's champion.
 * March 11 has the earliest known instance of a puzzle using all four lines of the puzzle board, in this case Round 2's A LITTLE KNOWLEDGE IS A DANGEROUS THING.
 * On March 11 and 12, Pat's Final Spin has the camera start at an overhead shot of the Wheel and zoom in to the red player's arrow (which is not flashing on March 11) as the Wheel stops.
 * March 11 has the first known instance of a contestant calling R, S, T, L, N and E in the bonus round (although not in that order).
 * March 12 has several notable events:
 * After Susan makes her entrance, Pat makes a remark about her outfit: "Zontar called, he said the invasion of Neptune is off." He makes a few more comments during the post-game chat, then admits he likes the outfit.
 * Just before the first spin, Pat holds up a cue card with a 4 drawn on the back and says "This is the number I drew, and that made me a loser." During the credits, Susan briefly holds up the card and appears to make a comment toward Pat.
 * Pat accidentally tells a contestant that an L has already been called in Round 1. He corrects himself later on in the round, since L is not in the puzzle.
 * Contestant Bill purchases 11 items after Round 2; with $1,103 remaining and nothing left to spend it on, he puts it on a gift certificate. The resulting prize copy runs for two minutes and ten seconds.
 * Bill sweeps the main game and wins a bedroom set in the bonus round.
 * The December 4, 1979 cue is used when going to commercial after the bonus round.
 * Susan forgets to turn a T in the bonus puzzle GILBERT AND SULLIVAN, and is reminded from offstage.
 * By March 12, Climax begins providing Susan's wardrobe; considering the strange outfits she wears on March 11 and 12, along with Pat's comments on the latter show, this association was probably short-lived.

April 1982 :
 * On April 26, the show moves back to 10:30, replacing Blockbusters.

May 1982 :

June 1982 :

July 1982 :

August 1982 :

Season 9 (1982-83)
September 1982 :

October 1982 :
 * October 22 is Susan's last episode, as she wishes to pursue charity work. As seen on the show's E! True Hollywood Story, she was presented with flowers and many of the crew said goodbye.
 * Beginning on October 25, the show rotates guest co-host duties among Summer Bartholomew, Vicky McCarty and Vanna White. It is currently unknown how long each guest-hosting stint lasted.

November 1982 :

December 1982 :
 * December 13 is Philadelphia Week, which is the same as the previous city-oriented weeks minus the returning champion from December 10. The open shows Pat in that city, waving in front of a large fountain.
 * On December 13, Vanna is officially named the show's second permanent hostess, although Pat's comments seem to imply that she had also done the previous few weeks. Vanna's first official puzzle is GENERAL HOSPITAL, and the first letter she turns is the T.
 * On at least December 13 and 29, there is a large pot of flowers behind each player.
 * On December 13, the camera mistakenly holds on a still shot of an $840 curio cabinet after Round 2 while Jack describes it. Also in that segment, the prize cue runs to its end and begins again.
 * On December 13, footage from Pat's trip to Philadelphia is shown just before the credits, and this is where Pat signs off.
 * By December 13, the money graphic and Wheel logo begin to be displayed in different colors.
 * By December 13, the commercial cues are changed up once again: The show's theme is used after Round 1, during the mid-show car plug, and after the bonus round; the December 4, 1979 cue is used during Round 2, after Round 2, and after Round 3.
 * By December 13, the Final Spin shot returns to normal (although the red arrow is again not flashing).
 * December 27 is Teen Week, which uses a version of what would eventually become the Friday Finals: Three contestants compete on Monday-Thursday, and the three biggest winners return on Friday to play for savings bonds. Despite this format, the opening for the week (see below) shows 14 contestants; it would hence be reasonable to assume that two of them were standby players.
 * By December 27, the normal opening for Teen Week is introduced: Three contestants model prizes, followed by all of the week's players sitting or standing in front of the puzzle board (reading TEEN WEEK on the middle two lines); the day's contestants then introduce themselves, followed by Pat and Vanna. The practice of the hosts being introduced together would become permanent on the nighttime show in late 1989.
 * On at least December 29, the contestants stand on boxes, a fact which Pat points out after Round 1.
 * On December 29, the first two puzzles are Phrase.
 * On December 29, during Round 2, Vanna accidentally turns the O in the puzzle EASIER SAID THAN DONE, but very quickly turns it back while she is still blocking the camera's view.
 * December 29 has the first known instance of a four-line puzzle in a Speed-Up round. The answer is THE NINA THE PINTA AND THE SANTA MARIA, which is also the first known instance of a puzzle being completely filled-in before the solve.
 * By December 29, the show's theme is again used for all commercial breaks (except after Round 2 on this episode, as it fades to black before any music can begin).
 * By December 29, the red arrow again flashes during the Final Spin.
 * By December 29, Pacino begins providing Vanna's wardrobe.

January 1983 :
 * On January 3, the show moves back to 11:00 AM.
 * The January 20 show is Episode #2,044.

February 1983 :

March 1983 :
 * March 28 is Teen Week.

April 1983 :
 * On April 1, several notable events happen:
 * During Round 1, both a ding and the applause machine are suddenly cut off after the I's are purchased.
 * No music is played during the commercial outro after Round 2, as it fades to black too quickly.
 * Five rounds are played, with $1,000 as the top value for Rounds 3-4 and $2,000 for Round 5.
 * In Round 3, contestant Trevor mis-solves the puzzle JUICE NEWTON as JOYCE NEWTON. A turn later, the "only vowels remain" beep fails to sound, although a stagehand can be heard telling Pat that only vowels remain. Contestant Juanita solves the puzzle for $50.
 * The bonus round is played for a four-person vacation to Disneyland, worth $5,302. The puzzle, THE ACADEMY AWARDS (Event), is not solved.
 * After the bonus round, Pat gives a hamburger "garnished" with $200 to the contestant. She is then given five hours of a chauffeured stretch limo, which drives out from behind the host's area and stops in front of Pat; the driver gets out and opens the back door, revealing Vanna. Afterward, all of the Teen Week contestants come onstage.
 * By April 1, and probably much earlier, the "house minimum" is $200.
 * By April 1, the December 4, 1979 cue returns for at least one commercial break (in this case, after Round 5) as well as after the bonus round.
 * By April 1, New Leaf begins providing Vanna's wardrobe.

May 1983 :
 * At some point in May, probably a Tuesday and definitely before the week of May 23, the Wheel's spikes are rewelded with a new method that makes the spins much quieter than they were previously (referred to by Pat the next day as "the 10,000-spin checkup").
 * On the above episode, a champion is retired.
 * An episode from May, known to be the day after the above, has some unusual events:
 * During the open, Pat honks a car's horn right after Jack introduces him.
 * Pat does the demo spin with both feet off the floor. Following the overhead shot, the camera returns to the position it had just before.
 * Before Round 2, the puzzle chime accidentally sounds while Pat is talking about the aforementioned Wheel update. He then mentions the $1,000 space and second Bankrupt, after which he says "I can take a hint". The chime then sounds again in its proper place.
 * After the Round 2 puzzle STEPHANIE POWERS is solved, the O does not light up at first. Vanna merely stands in front of it, apparently waiting for it to light up, then looks to her right and turns the trilon anyway. The O does not light up until after the puzzle is fully revealed.
 * During Round 3, contestant Paul calls for either A (a vowel) or H (already in the puzzle) and stops himself halfway, then says S. Pat briefly consults the judges, after which Paul is credited with the S, which is not in the puzzle. The next player, Jackie, calls for H and loses her turn as well.
 * Pat's Final Spin lands on Lose a Turn.
 * After Round 3, contestant Penny's score display goes blank. The dollar sign on Paul's display is still present.
 * There are two sets of repeated categories: Phrase in Rounds 1 and 3, Person in Round 2, and People in the bonus round.
 * By the above episode, the commercial outro cue pattern is changed once again: The show's theme is played after Round 1, during Round 3, and during the mid-show catalog plug; the December 4, 1979 cue is played after Rounds 2 and 3 plus after the bonus round.
 * By the above episode, Climax begins providing Vanna's wardrobe; unlike the period where the company provided Susan's wardrobe, it is now credited as "Climax of California".

June 1983 :

July 1983 :

August 1983 :
 * On August 8, Thicke's music package is replaced with a new music package composed by Griffin, including a new theme tune called "Changing Keys". The last three notes of "Changing Keys" are also the cue for solving a puzzle.
 * Shopping rounds use a music cue called "Nightwalk" as the contestant buys prizes, and a variety of cues for the prize descriptions (including "Frisco Disco", the closing theme of the 1978-79 Jeopardy! revival).
 * "Changing Keys" is also used for all commercial breaks, ending a three-year period where Thicke's three commercial cues ("Big Wheels"; December 4, 1979; and electric-guitar) were generally inconsistent in their use.
 * For its first year of use, "Changing Keys" is cued up at the 0:56 mark during the intro, and until around October 1987, the bridge plays when Vanna walks out. The instrumentation is also more "chirpy" for the first few months.

Season 10 (1983-84)
September 1983 :

October 1983 :
 * October 31 has several events:
 * During Round 1, Pat forgets to ask a contestant if he wants to use his Free Spin.
 * After Round 1, the transition to the turntable is that from the opening, and briefly "sticks" halfway.
 * Jack's prize description after Round 3 ends abruptly following the last item, with the "s" in "dollars" being cut off; oddly, the prize cue is still playing.
 * Rounds 3 and 4 are Thing.
 * The bonus puzzle, WIN LOSE OR DRAW, uses all four lines of the puzzle board. It is not known why this was done, as the answer would fit easily on two.
 * By October 31, Jon Wesley begins providing Vanna's wardrobe.

November 1983 :
 * November 1 begins the Home Puzzle Contest, the show's first home-viewer sweepstakes. Portions of a puzzle are revealed each day this week, and the winners receive a microwave oven with accessories; a set of kitchen appliances; or a "video package" including a television and a video tape recorder.
 * November 7 is likely the show's first Couples Week, with three husband-and-wife teams ranging from engaged to being married for 40 years. The format is similar to the Teen Week, with the highest-scoring couples returning on Friday for a chance at a 1984 "American luxury car". The opening shot of the puzzle board has COUPLES WEEK on the middle two lines.
 * Oddly, the opening on at least November 9 shows just eight couples. It is likely that the opening was reshot throughout the week as couples were eliminated.
 * Several events happen on November 9:
 * During Round 1, the first couple's score display goes out twice: Once during the round, and again after the puzzle is solved. The display does not return by the commercial break. (They are the only couple to play Round 1.)
 * Pat is shown in the chroma-key circle after Round 3.
 * All four puzzles are Phrase.
 * The winning couple plays for a big-screen TV in the bonus round, but fail to solve TOP SECRET with T__ SE_RET showing. The husband then remarks "Oh, that was so easy!"
 * By November 9, a bumper is added after Round 2 showing the turntable spinning into place for Round 3 with a Wheel of Fortune logo at the top. The Wheel logo is in a different shape and font than any "official" logo (including the one in use at this point), and is displayed in various colors.
 * By November 9, Giorgio of Beverly Hills begins providing Vanna's wardrobe.
 * As of November 9, the Merv Griffin Productions logo used in the credit roll is still the original one.

December 1983 :

January 1984 :
 * An episode from around January has several notable events:
 * The Wheel spins very slowly during the open.
 * Rounds 1 and 2 are both Phrase.
 * Before Round 2, the audience gets overly excited after Pat mentions the presence of two apostrophes in the puzzle.
 * During Round 2, two players in a row call a letter that is already in the puzzle.

February 1984 :
 * February 27 is probably the show's first Battle of the Sexes week. The Monday-Thursday games each feature three women or three men playing, with the top winner of each sex playing on Friday for a shot at $5,000 in the bonus round.
 * The opening for Battle of the Sexes shows the week's contestants playing a tug-of-war in front of the puzzle board, which reads BATTLE OF THE SEXES on the middle two lines. There are six men and seven women, implying that one of the ladies was a standby.
 * February 29 has several notable events:
 * The Wheel spins very slowly during the open and close.
 * Before Round 2, Pat brings up a question from contestant Ray, who thought Pat was in the film Raiders from Outer Space (actually an episode of the 1960s anthology series The Time Tunnel). Pat remarks that he doesn't recall such a role, and it was probably another game show host. Pat and Vanna discuss this a bit further after the game.
 * The Round 2 puzzle is SARAH PURCELL. While Pat credits her as being from fellow NBC show Real People, she had previously co-hosted The Better Sex (a 1977-78 game show whose premise was a battle of the sexes). It is not certain whether the presence of her name during this particular week was an intentional reference.
 * There are two sets of repeated categories: Phrase in Rounds 1 and 4, Thing in Round 3 and the Bonus Round.
 * Pat and Vanna can be heard talking during the credits.
 * By February 28, Jon Wesley begins providing Vanna's wardrobe again.
 * By February 29, the Merv Griffin Productions logo in the credits has been replaced by a full-color drawing of a griffin against a black background.

March 1984 :

April 1984 :

May 1984 :
 * Beginning May 7, Pat and Vanna play Dream House for the first week of a two-week All-Star Charity Tournament against Jamie Farr and Kari Michaelson; Pat and Vanna play for the American Cancer Society (winning $9,450), while Jamie and Kari play for the Juvenile Diabetes Foundation (winning $10,300).

June 1984 :

July 1984 :

August 1984 :
 * Around this point, "Changing Keys" is re-orchestrated slightly. A glissando is added to the beginning, and the instrumentation is less "chirpy". The theme now begins from the first bar during the intro, instead of the 0:56 mark.

Season 11 (1984-85)
September 1984 :

October 1984 :

November 1984 :

December 1984 :
 * As of December 19, the logo shown after the money graphic is still the original one.
 * As of December 19, the category strips still use the computerized font.

January 1985 :

February 1985 :
 * By February 1, the logo shown after the money graphic is updated to an animated one.
 * By February 1, the category strips are updated to a bold Helvetica font, in one of several colors (most often matching Vanna's outfit) with a white outline. Winning totals after the bonus round also flash in the same font.

March 1985 :

April 1985 :

May 1985 :

June 1986 :
 * June 16 is Teen Week.
 * For the week of June 16, Susan briefly returns to fill in for Vanna, who has the week off (a then-recent plane crash killed her spouse, John Gibson).
 * On at least June 20, no credit is given for Susan's wardrobe.
 * June 20 has two sets of repeated categories: Phrase in Round 1 and the bonus round, Things in Round 3, and Thing in Round 4.

July 1986 :
 * On an episode at some point during the Summer, a contestant acquires five Free Spins, and uses all five in Round 2.
 * On the above episode, Round 3 starts as a Speed-Up. Thanks to a $2,000 Final Spin, the blue contestant ends up winning despite having not touched the Wheel at all.

August 1986 :

Season 13 (1986-87)
September 1986 :
 * September 15 is the debut of the daytime version's Jackpot wedge. The Jackpot begins at $1,000 and increases by $1,000 each day until it is won.

October 1986 :

November 1986 :
 * The November 13 game ends in a tie. As a result, no bonus round is played, and all three contestants continue the next day. The returning champion, who is not one of the tied contestants, is informed that the next day's game will be a "contiunation of [her] second appearance". In place of the bonus round, Pat shows the device from which contestants draw numbers to determine who starts the game.
 * November 17 is a College Week.

December 1986 :
 * December 22 is a Teen Week. During the entire week, there is a large bow on the puzzle board's frame.
 * On December 22, the bonus round timer continues to play for about two seconds after the buzzer sounds.

January 1987 :

February 1987 :
 * February 9 is a Battle of the Sexes week. The open is the same, with the genders' positions swapped and the puzzle board reading BATTLE OF THE SEXES on the top three lines; oddly, there are eight women and seven men.

March 1987 :


 * On March 30, it takes six turns to reveal any of the letters in the Round 1 puzzle HO CHI MINH. With only the O missing, a contestant mispronounces the name; the next constestant solves for the house minimum of $200, then buys the ceramic Dalmatian and puts the rest on a gift certificate.

April 1987 :
 * As of April 27, commercial breaks may still occur in the middle of a round (Round 2 in this case).
 * On April 27, the puzzle board reads BEAST during the credits. This was done, presumably by Pat, by rearranging the letters in the bonus puzzle BEST MAN. He is known to have scrambled the bonus puzzle on at least two other occasions.

May 1987 :

June 1987 :
 * On or around June 5, a contestant wins a Jackpot of $21,000. This is believed to be the highest total ever achieved with the Jackpot.

November 1988 :

December 1988 :

January 1989 :
 * January 9 is Pat's last daytime show. He steps down from daytime to host his short-lived talk show, The Pat Sajak Show.
 * Appropriately, the Round 1 puzzle is TAKE GOOD CARE OF YOURSELF.
 * Following the bonus round, Pat makes out with Vanna until series creator Merv Griffin walks up and pokes Pat's shoulder.
 * No name is ever given for Pat's replacement, likely because no host had been selected yet.
 * On January 10, M.G.'s introductory spiel ends with "And now, here is your hostess: Vanna White!" Vanna walks out to the host's area, and introduces new daytime Wheel host Rolf Benirschke. The two converse during the first segment (which lasts just under two minutes), and Round 1 begins in the second segment.
 * January 10 contestant Cheryl Gilmore previously won the top prize on The $1,000,000 Chance of a Lifetime.

February 1989 :
 * On an episode during Rolf's tenure, for what is believed to be the first time, a contestant incorrectly solves a fully-revealed puzzle. The answer is SAINT THOMAS AQUINAS, which at least one player mispronounces.
 * On two different episodes during Rolf's tenure, the show ends in a tie. On the first instance, Rolf admits on-camera that he does not know what to do.
 * There is a Teen Week during Rolf's tenure. On one of those episodes, he congratulates himself for hitting $2,000 in a Final Spin; a contestant then points out that Rolf is looking at the wrong arrow and has actually hit Bankrupt.
 * Charlie O'Donnell returns as announcer on February 20.
 * On February 22, contestant Lois gets three Free Spins in Round 1.
 * On February 22, Rolf's Final Spin lands on Lose A Turn.

 * By June 30, Rick Pallack begins providing the host's wardrobe.
 * On June 30, Charlie says his name while signing off, the only known instance of any daytime announcer doing so.

July 1989 :
 * On July 17, the show moves to CBS at its original timeslot of 10:30 AM. Among the changes are:
 * 1) Bob Goen becomes the show's host.
 * 2) The show now tapes at CBS Studio 33.
 * 3) The shopping format is retired, replaced by a scaled-down version of the nighttime version's play-for-cash format. The shopping cue "Nightwalk" is sporadically used as a prize cue.
 * 4) The "wrong letter" buzzer, Bankrupt slide whistle, "only vowels remain" beep, Final Spin bells and category chimes are all changed to the current ones. Also, unsolved bonus puzzles are now followed by two short buzzes instead of the "wrong letter" buzzer.
 * 5) "Changing Keys" and the puzzle-solve cue are given new arrangements This and all subsequent versions of "Changing Keys" end on a single note instead of the puzzle-solve cue.
 * 6) The contestant nametags are now parallelogram-shaped with white letters.
 * 7) The Wheel offers far less than it did previously: $500 is once again top value for Round 1, $750 for Round 2, and $1,250 thereafter. For the first time since 1975, $50 and $75 appear on the Wheel.
 * 8) A new prize is added in each of the first three rounds.
 * 9) Vowels now cost $200.
 * 10) The bonus round now offers subcompact cars and a cash prize of $5,000. The latter is displayed on a rotating green disc suspended from the ceiling. While the nighttime version changes bonus round prize selection to a random draw from envelopes spelling W-H-E-E-L in September 1989, daytime still allows contestants to pick their own bonus prize until the daytime version is canceled. Picking the cash is not as common on daytime as it had been on nighttime at this point.
 * The returning champion from Rolf's last episode does not return on July 17.
 * Charlie's intro on Bob's first episode is, "From Television City in Hollywood, It's America's most watched game show! The famous Wheel is spinning your way with lots of cash and an assortment of fabulous and exciting prizes! And now, here's your host, Bob Goen!"
 * July 17 is the debut of Person/Fictional Character, which is renamed to its current name of Star/Role by 1990.
 * On July 17, Pat Sajak makes a cameo before Round 3 to wish Bob good luck.
 * On July 18, Charlie's intro changes to "Look at this studio, filled with lots of exciting prizes! Including our all-new $5,000 cash bonus, a gorgeous handwoven oriental rug, and a fabulous sapphire and diamond ring, plus thousands of dollars in cash, all waiting to be won on today's show! Yes, from Television City in Hollywood, it's Wheel of Fortune! And now, here's your host, Bob Goen!"
 * On July 18, the two-digit values are given diamonds. In addition, the yellow $50 near Bankrupt in Round 1 is increased to $300.
 * Charlie's intro changes again on the 19th. "Lots of exciting prizes" is changed to "wonderful and exciting prizes", and the next several episodes use a different phrase to describe the $5,000.
 * On July 19, the contestant nametags change to black lettering on a gray background.
 * On July 19, the Round 1 Wheel undergoes several value changes: The aforementioned $300 drops to $125, the $125 formerly next to it drops to $50, the pink $50 between Bankrupt and Free Spin increases to $175, the purple $50 nearby increases to $300, and the blue $75 between Free Spin and Lose A Turn increases to $200.

 * For a few weeks around this point, on both daytime and nighttime, some O's on the board are wider and rounder than usual, clearly not matching the font of the other letters. They are believed to have been zeroes loaded in by mistake.
 * By September 18, the Round 1 minimum is increased to $100: The pink $50 is increased to $250, the blue $75 is increased to $400, and the purple $300 near Bankrupt is decreased to $100.

Round 1's prize (a piece of art) starts on the pink $250, then moves to the yellow $200 for Rounds 2 and 3; Round 2's prize (a ring) starts on the purple $100 and moves to the blue $100, with the Round 3 prize (a spa) taking the ring's place in Round 3.

April 1991 :

June 1991 :

July 1991 :

August 1991 :

 * September 20 is the last daytime episode, although the show appears to have gone into reruns by this point.
 * On what is believed to be the finale, the total of the Round 1 prize flashes on a chyron when a contestant picks it up during Round 1. Considering the similar event on March 11, this probably happened semi-regularly.
 * It was once rumored that Wheel continued through December 31, 1993 in first-run or repeats along with reruns of Classic Concentration. While there have been cases of affiliates showing repeats of cancelled network games (the original versions of Jeopardy! and Gambit), and Classic Concentration was indeed rerun until that date, the idea of daytime Wheel continuing for another two years is (as far as anyone can tell) merely a bit of wishful thinking.

Wheel 2000 (1997-98)

 * While Wheel 2000 did air in daytime on network television, it is considered a derivative and not a revival of the daytime show. See Wheel 2000.
