Gameplay
The goal of this game is to move a hand's fingers up or down to defeat its opponent in a game of rock-paper-scissors. The opponent has his or her hand in the shape of a "rock", "paper", or "scissors". The player must change the fingers on the big hand by tapping them to beat his or her opponent.

In the WarioWare Gold version of the game, the player will occasionally control the opponent's hand instead, and must lose to Wario.
