When no fingers are left, the final player counted is selected. Allowing zero Some variants of morra allow players to hold out zero fingers. If the total number of fingers is also equal to zero, the game is usually counted as a draw and replayed. Shish-Nu Shish-Nu is a variation of Morra where the rules are to hold out fists and stick out your thumbs only. The game works best with a large number of players. The game is played by every player holding out their fists with no thumbs raised. Then, all players say "Shish-Nu" and then the number of thumbs they guess will be up. The number correlates to the number of players in the game as well. Chin Chin Chin Chin is a variant most closely related to Shish-Nu, the main difference being that Chin Chin is more turn-based. Chin Chin is most popular in the US. To play Chin Chin players hold out their fists with no thumbs raised. Turns go clockwise around the group and the player whose turn it is shouts "Chin Chin" and a number. Immediately players put up a random number of thumbs. If the player correctly shouts the number of thumbs up in the group he wins the round and places a hand behind his back. This repeats and the person who is first to lose both hands wins. Fifteen-Twenty Fifteen-Twenty is an old Chinese variant of morra with numerous variations of its own played in different parts of Asia. Two players face off in this game with both of their hands in front of them, face-to-face. Players take turns guessing the number of total fingers that are shown each round. Players can hold out either two fists (0), a fist and an open hand (5), or two open hands (10). As such, the total number of fingers that can be guessed is 0, 5, 10, 15, or 20. When a player makes a guess (a round), both players can change the number of fingers currently being held up. If the previous player made a wrong guess, the opponent can immediately start the new round and make a new guess without delay (sometimes catching the other player off guard before they are able to change their fingers). If a player guesses correctly, he immediately gets to guess again. Guessing correct on the second try wins the game. If a player makes
