Players play number cards adding to a shared running sum. No player may send the sum over 101, and a player is eliminated if unable to make any plays. Most cards are 1-10 number cards, but special cards include reversing the turn order, passing a turn, subtracting 10 from the total, adding 50, and setting the total to exactly 101. Players pass around "101 chits" to record victory, and a player wins upon collecting enough 101 chits from his/her opponents.
