Four players compete in five rounds. In each round, a "money clock" will rapidly increase or decrease, and players must secretly lock in an amount of money they think is enough for them by pressing a button they hold behind their back. The object of the game is to avoid being the greediest player. Whoever locked in the highest amount of money in a round banks nothing from the money clock played in that round, while the other three players banked whatever they locked in from that money clock. The maximum amount of money in each round is $1,000, $2,000, $3,000, $4,000, and $5,000, in that order.
