The game consists of 2 players taking turns taking chips from a pile of 21. The one who thatkes the remaining number of chips on their turn wins. However, the maximum amount of chips a player can take on their turn is 3. Each turn, the designated player must take at least 1 chips from the pile. If there is less than 3 chips remaining in the pile, the player cannot take more than than there is remaining (eg. taking 3 when there is 1 chip remaining). Before the game, the players choose the number of rounds they wish to play and play that number of rounds. The maximum number of rounds a player can play is 5, and the minimum is 1. Once the correct number of rounds have been played, the player who wins the most rounds will be the overall winner of the game. A tie can happen, and if this occurs, the result will be stated at the end of the game.
