Your goal in Rock, Paper, Scissors, BANG! is to build towers of pieces in your own colour, while attempting to stop your opponent building towers in their colour.
Each tower you own is worth it's height-1 in points at the end of the game. Dynamite can be used to remove tiles permanently from the game. You must take a piece each time you move by either beating it, or drawing with it (following rules for Rock, Paper, Scissors). Dynamite beats everything but each piece can only be used once.
