Rock, Paper, Scissors, BANG! is an abstract two-player strategy game played on a 5x5 board. Each player has twelve pieces: three each of Rock, Paper, Scissors and Dynamite. The game is played in two parts:

• Part 1: Players take turns placing individual pieces on the board.
• Part 2: Players take turns moving pieces to make towers, moving towers to make bigger towers, and moving dynamite to remove pieces and towers from the board.

If both players "pass" consecutively or neither player can make a move, the game ends. Each player scores all of his towers, with each tower being worth a number of points equal to its height minus 1. Whoever has the highest score wins.
