Vingt-et-un is a short-lived, French-Canadian adaptation of the 2000 revival of the American game show Twenty-One.
Gameplay
Main Game
Two contestants (a champion and his/her opponent) are placed in a soundproof booth with their headphones on. The game was played for up to three rounds. The goal is to score 21 points, or have the greater number of points to win after three rounds to win. In each round, a category was given, each category has eleven questions of increasing difficulty, they ranged in value from 1 to 11 (one point being the easiest, eleven being the hardest). So the higher the value, the more difficult the questions. All questions have four possible choices.
The player who's booth is on picked a point value to play for, and then a question worth that value was asked by the host. A correct answer wins points, but a wrong answer loses a life. Each player has three lives per game. After three lives lost, that player automatically loses (it is possible for both players to lose the game due to the loss of three lives). The challenger played first in each round, and then after the challenger played his/her question, his/her booth is turned off and the champion plays with the same category. The players are not aware of their opponent's score.
After two rounds, the two booths are then open and they are given the option to stop the game if one of the players ended the game, the one that leads to this point wins. If the opponent scores 21 points before the champion does, the champion was given one chance to catch up to achieve a tie (the booth of the opponent is open to hear the rest of the game).
Second Chance/Call Using
Once per game, a player may call his/her "Second Chance", which is a designated person (a friend or family member) to help answer a question. In this case, if the player gets an answer, (s)he loses two lives (so it is possible for either or both players to lose the game due to the loss of three lives in just two rounds).
Tiebreaker
If the game ends in a tie, then both contestants are asked a question and the first one to ring in can answer. If he/she answers the question correctly, then (s)he wins the game and plays the bonus game. if (s)he gets the question wrong, the his/her opponent has the right to answer. However, if both opponents get the question wrong, then the question is thrown out and a new one is in play.
Payoffs
The winner of each game won money for that game.
The amounts are based on this structure:
- Part 1: $250
- Part 2: $500
- Part 3: $1,500
- Part 4: $3,500
- Part 5: $5,500
- Part 6: $12,500
- Part 7: $20,000
After the seventh game, the eighth game would be $250, and so on until (s)he lost it and leave with all the amounts gained from the previous games.
Bonus Game
The winner of the match gets to play the bonus game. The champion was given a category, where six true or false questions were asked. Each question was worth from $100 to $600 (per $100 accumulated). At anytime, (s)he can stop after each correct answer was given. However, a wrong answer ends the game and all his/her money was lost from the round (although the money that was earned prior to that is guaranteed to be kept no matter what happens). A maximum of $2,100 can be won in the round.
