In The Gang, a cooperative version of Texas Hold'em, players bet on how good they think their hand will be compared to the other players' hands.
At the beginning of each round, without talking to each other, each player selects a chip that shows how good they think their hand will be. Then, cards are dealt to the center of the table and players have the chance to reassess their hand as more cards are revealed.
At the end of the round, players see if they estimated their hand correctly. If all players succeed, you open one of the bank's vaults! If not, the alarm is triggered! If you manage to open three vaults before the alarm goes off three times, your gang wins!
