Almost: a cooperative-competitive game for three or more players by Yehuda Berlinger.
Components: pencil and paper, ten bidding markers for each player
For N players, the game is played over N-1 rounds.
On each round, each player secretly selects a number to bid, by placing some number of bidding markers in his or her fist. Reveal all bids simultaneously. The player who bid the lowest unique value wins a number of points equal to his or her bid.
For example: if two players bid 5, one bid 6, one bid 7, and two bid 10, then the player who bid 6 gains 6 points. It is possible that no player gains points for a given round.
All players who score 10 or more points win the game.
Players may discuss their bidding strategy before each round. It is recommended to place a time limit on these discussions. All players must bid every round, and the minimum bid is 1.
