Abstract strategy game played on a board divided into two "hemispheres" of 10 spaces each, plus an "equator" of nine spaces. Each player receives 10 pieces of five different sizes which are placed in their hemisphere. The game consists of five "battles", in each of which each player plays up to two pieces onto the equator. Only some pieces may be legally played depending on which spaces on the equator have been occupied, and the winner of the battle is determined by the sizes of the pieces. The winner is the player who has won the majority of the pieces in battles, after all five battles are complete. —user summary
