"Cosmoscacchi" is a chess/checkers-like wargame that utilize the 5" characters of the Galaxy Series, produced by Atlantic in the '70s years of the last century. The players can move their pieces on the board in different ways based on the type of Character used (no dice rolls involved). The Characters can shoot each other if there is a direct stright or diagonal line between them. The shooting is resolved revolving the "Fire Wheel": if the wheel shows a number equal to the distance between the Characters, the round hit the choosen target, otherwise it miss. If the wheel stop on a space with no number the shooter's weapon jam.
