The game is played with three possible hand signals that represent a rock, paper, and scissors. The rock is a closed fist; paper is a flat hand with fingers and thumb extended and the palm facing downward; and scissors is a fist with the index and middle fingers fully extended toward the opposing player. Rock wins against scissors; paper wins against rock; and scissors wins against paper. If both players throw the same hand signal, it is considered a tie, and play resumes until there is a clear winner.[Reference]
