The game is rock, paper, scissors (with "well", which takes rock and scissors) played on a 4 x 6 board.
Players have four different tokens (rock, scissors, paper and well) which are placed on their starting row. Pieces can move only one square at a time, with taking a piece according to the expected rules (rock takes scissors, etc.).
The winner is the first player who can move any of their tokens to the opponents baseline.
