“Chopsticks” is a game played between the app and the user where each player tries to get the other out. Each player has two hands, and they are out when both hands are out. Players start with one finger "up." A player can add fingers to their opponent by selecting one of their own hands using a toggle to add to one of their opponents. Their fingers are added to the opponent's fingers to calculate how many fingers are up. The player who is taking a turn does not experience a change in their number of fingers that are up, only their opponent's fingers change. If the fingers up on one hand add up to exactly 5 that hand is out. Otherwise, if the sum is more than 5, the difference between the sum and 5 is the number of fingers that is up for that hand.
