The top and bottom of the game board are considered to be connected, as well as the two sides with each other, forming a donut shaped playing field (also known as a Torus). All pieces move like a Rook in Chess, that is, any number of squares horizontally or vertically in an unobstructed straight line. Chocolate tries to eliminate Powdered. Powdered tries to eliminate Strawberry. Strawberry tires to eliminate Chocolate. A player wins when he is able to reduce his designated opponent to less than half their initial force (four pieces or less).

The game uses the complementary methods of capture known as "custodianship" and "intervention." If a Donut moves orthogonally next to an enemy piece and there is another friendly piece directly beyond that, the enemy piece is squeezed between the two pieces and captured. This effects a capture by custodianship.

Capture by intervention is its reverse. If a Donut steps between two orthogonally placed enemy pieces, it captures them both. The two pieces captured do not have to be from the same player. They can be one piece from each of the two other players. It is possible to move so as to capture in more than one direction at a time.
