The board is 8x8 with the squares rotated 45 degrees. The central 4x4 area forms the King's Court. The starting setup places the green and orange pieces on the 48 squares surrounding the Court. The opening moves have both players enter a piece onto the Court from opposing sides (no jumping yet).
From that point on, a piece must be present on the Court at all times --otherwise the player loses. Pieces move as in Checkers except they all move as Kings (no restrictions on direction). Jumps are again as in Checkers, except that you can jump your own pieces as well (without capturing them, of course).
