a sort of marbles chess

grabcad

unfurnished rules: the game is played much like chess you assemble the board as in figure players alternate turn in turn, the player may play one of these: - place a piece - changing the position of a piece - throws the sphere (if the player chooses to do this, both player throws the sphere at same time) Wins who make the sphere reach the opponent goal (the place alongside the ramp). PS: To play we need a 10 mm sphere.
