BOARD & PIECES:
FlipFlop is played between two opponents on a 3 x 3 square board. There is a variant of the game for a square board of 5 x 5. Each player has 3 (5 for 5 x 5 boards) pieces, which have two faces: The Bishop and the Rook.

GOAL:
You win when any of your pieces is placed in the middle square in the last row, your goal square (i.e., the third row center file for white, and the first row center file for black when played on 3x3 boards), for two consecutive turns, or when there is no legitimate moves left for your opponent.

The game ends in a draw if the identical position appears on the board for three times.

MOVEMENT:
All pieces start as Rook, arranged on the first row on each end. As in normal chess games, Rooks move in a straight line, horizontally or vertically and Bishops move in a straight diagonal line, as far as they want.

The player with the white pieces commences the game.

After each move, pieces are flipped to the other side: from Rook to Bishop, then from Bishop to Rook.

Pieces cannot be captured, except when they are either in your or opponent's goal square.
