This game is played on a 7x7 square
board, with the following setup:
||SLIDE - A stone
may slide one cell in any orthogonal direction, and

||To slide a stone, there must be
access to it. For example, to slide a stone to the left, the space just to the right

||KO rule -

||The player cannot push his own
stones off the board.
