Win by moving a piece to the opposite side.
Pieces move forward or diagonally forward and capture diagonally forward.
Because the pieces have no choice but to move forward, the game develops quickly. Draws are impossible. The game is similar to a pawn promotion battle, except that the pieces move diagonally forward even when not capturing. This diagonal motion allows you to 'skirt' by an opponent piece by facing it head on, where it cannot capture you, and then moving diagonally around it. As a result, a single piece cannot by itself prevent an opponent piece from 'breaking through' the ranks.
