Twenty One 1957

Based on the original (1956-58) scandal-riddled game show, one player acts as Quiz Master for two players or teams and chooses a random category for the round. In turn, each secretly chooses a question by number. There are eleven questions, numbered 1-11, and are of graduated difficulty with 11 being the hardest. A right answer adds that amount to their score, a wrong answer takes it away (but scores cannot go below zero).

Neither team knows the other's score, and either may stop the game at any time. The game ends when either 1) a team asks to stop the game or 2) one team has 21 at the end of the round, and the winners receive $500 for each point difference in the scores.

If the game ends in a tie, another game begins at zero with the cash award increased by $500 per point. The team with the most money at the end of gameplay (set by the players) wins.
