The format used in the tournament is a modified version of the pool game nine-ball, that emulates Texas Hold 'em, the most popular variation of poker. Each of the four players carries chips like those used in poker. In each rack, the players wager a number of them. The winner of that particular rack collects the others' wagers. If a player's chips is less than wager, that player has to go "all in" which means all of that player's chips must be wagered. After every four , the wager rises. In later racks, the player with the fewest chips will have to wager all. If a player runs out of chips, he/she is eliminated from the match.
