The object of the game is to place all of your pieces onto the playing surface before your opponent can place all of theirs. Each player receives 18 pieces in their colour. The pieces either show a 'rock', 'scissors', or 'paper' symbol. Each turn you must play your "reserve" tile that you selected the previous turn, and then select a new tile for your reserve, anticipating your opponent's next move. Placements rules are basically that your symbol must overpower at least one other symbol beside it (using standard rock-scissors-paper rules.) You lose a turn if you can't place your reserve piece onto the board, and you must then choose a new reserve piece for your next turn.
