This game is played on the following board:
A remark: If there are 2 stones at top of the pyramid, the player can move one to the goal cell and win. But only, if he is not forced to fall down with one of these pieces! However, is is possible to make the winning move, if there is a further falling piece in another level of the pyramid. Because in this case, the player are not forced to fall down with the piece at the top level of the pyramid!
Despite the apparent disadvantage, Green can win in 6 moves, by dropping at cell e5 . Then, f6-e6, d5-d6, e8-d8, d5, h8-g8, f7-f8, g7-f7, e5-d5, g8-g7 (the stone falls), f8-e8 and wins by stalemating Violet.
There is a ZRF to play Pyramid with Zillions.
