-Card Sharks from 2001...the winning contestant received $2,100, which was then split up over three levels on the Money Cards. A few contestants bet it all and lost as a result*.
Card Sharks from 2019, too. The $10,000 each contestant receives for winning the main game is what they're betting in the Money Cards.
I know I've seen at least one game of
Classic Concentration where a contestant had no prizes when time was called, solved the rebus, and then failed to win a car. But I can't remember if they won anything in a previous/subsequent game.
And since the subject is games where you can *theoretically* win and still receive nothing...
- Any version of
Family Feud where the main game is played for points. But I can't imagine anybody's ever been completely shut out in Fast Money.
- The second season of Liza Koshy–hosted
Double Dare is played for points in the main game. I would hope that there aren't any episodes where the team fails to complete the first obstacle.
