The playing field is made up of 67 points, 17 white and 50 Blue. The 3 Americans (blue) men are set up in the white on the starting points and the 50 Japanese (yellow) on the 50 blue points.

The object of the game is for the Japanese Field Army to get control of the Defense Area (the 17 white points) by having an army on each point. The Defense Army must stop the Field Army. Only the Defense Army (blue) can remove enemies by jumping over an occupied point into an empty point as in checkers and multiple jumps are allowed. The blue armies can only be removed if they refuse a jump.

Victory occurs when either the Japanese Field Army occupies all 17 points in the Defense Area or when it becomes impossible for them to do so (the Defense army kills more than 33 Japanese men).
