A GameShow gimmick to allows home players to play the game, generally played during ratings sweeps periods, and usually by sending in postcards in the 1950s through the 1980s, calling a 900 number in the 1990s, and going to the show's Web site in the current era. Generally the host will offer an easy first question, with harder questions to come.

For a variant which consists of audience-only game play, see PhoneInGameShows.
!!GameShows that featured Home Participation Sweepstakes:

* Both ''Series/{{Jeopardy}}'' and ''Series/WheelOfFortune'' offered phone games in the 1980s, played over a touch-tone phone. ''Wheel'' currently offers home viewers chances to win prizes from its "Prize Puzzle" rounds, which features cross-promotion with the Sony Rewards program as well.
** The ''Phone Jeopardy!'' ad is where that infamous [[http://www.youtube.com/watch?v=GU2w72KAkQQ viral outtake reel]] of Alex Trebek [[ClusterFBomb spouting his mouth]] came from, by the way.
* ''Series/TheChallengers''
* The 1990s ''Series/ToTellTheTruth'' featured host Alex Trebek giving away dates with Creator/{{NBC}} SoapOpera stars to female viewers, one of whom later appeared in the show's "One on One" audience game.
* ''Series/ThePriceIsRight'': The Creator/BillCullen era had Showcases as its sweepstakes, where viewers could send in their total bid on a series of prizes to be eligible to win the entire lot.
** The 1972 revival did not immediately have such a sweepstakes, but re-purposed Showcases as the final round for the two remaining in-studio contestants (get closer to your Showcase's price in total than your opponent with theirs without going over to win). By the 1980's, the CBS version would begin holding "Home Viewer Showcase" sweepstakes from time to time, which were done much like their 1960's counterpart. Around the same period, the show also offered "The Phone Home Game", a pricing game where an in-studio and home contestant on the phone could split up to $15,000 in cash.
** The "Win-at-Home" game made an appearance one year into Drew Carey's reign (which involves calling a 1-800 number where you will also allegedly hear "money-saving offers"), and Home Viewer Showcases were also briefly revived as well. A more frequent appearance are promotions for online giveaways tied to certain prizes (especially when something is given away to the entire audience).
* The whole late 1980s/early 1990s NBC game show line-up (back when NBC ''had'' a game show line-up) ''Series/{{Blockbusters}}''/''[[{{Series/Concentration}} Classic Concentration]]'', ''Series/{{Scrabble}}'', ''Wheel of Fortune'' and ''Series/WinLoseOrDraw'' would often do combined contests, such as 1987's "[[IncrediblyLamePun Car-razy]] February".
** When Bob Clayton was the host of ''Concentration'', home viewers' postcards were entered into a drawing. The first letter of a viewer's last name was worth a prize behind the corresponding number on the rebus board.
* ''Series/CatchPhrase'' encouraged home viewers to submit puzzles drawn on postcards. If your puzzle was used on the show, a ''Catch Phrase'' T-shirt would be sent to you.
* ''Series/DealOrNoDeal'' (The U.S. version) had "The Lucky Case Game". A graphic of five cases would be displayed and people would text which one they thought held money. Texts with the correct case number would be collected and a winner drawn and announced at the end of the broadcast.
* ''Series/PressYourLuck'' for a time had a special "Home Viewer Spin". Each contestant had a postcard from a different home viewer. Wherever the board was stopped, that prize or cash amount would be sent to the home viewer. If the board was stopped on a {{Whammy}}, the home viewer received a check for $500.
* Just about every generic phone-in quiz show can be classified as this.
* ''Radio/WaitWaitDontTellMe'' has several different home listener quizzes, including "Not My Job" where a celebrity will play on behalf of a prechosen listener.
* UsefulNotes/{{Chicago}} ''Bozo's Circus'' had the Grand Prize Game, where an audience member tosses ping pong balls into buckets to win prizes. Each player would also be playing for someone at home, whose postcard would be drawn out of the Bozo Drum before the game started. The home "player" would receive the same prizes the in studio player won.
