This game is played on the following 3x4 square board:

  • TURN - White starts. At each turn each player moves his stone to a valid cell:
    • The black stone may move to an adjacent (orthogonal or diagonal) empty cell where the white stone cannot move.
    • The white stone may slide in any direction (orthogonal or diagonal) stopping at a cell where the black stone cannot move.
  • GOAL - White wins if the black stone reaches the opposite corner cell (the green spot), Black wins if it is able to prolong the game indefinitely.
An example

If White moves to the red dot, it will win, since the black stone can only go to the goal corner that Black is trying to avoid.
