Twista is a version of the game Twister except played with the fingers and using musical notes to signal where players should place their fingers. Ideally, the computer will play a note, and the first player must press a colored key that corresponds to that note (3 colors, 3 notes). Once they've successfully done so, they hold their finger on that key, and the computer plays another note for the second player. The process continues until all keys are pressed or a player lifts a finger and loses.
