A curious abstract strategy game. The box forms the board; 32 squares plus a mirror which fits at right angles to the board producing a total playing surface of 64 squares. Each piece on the real side of the board has a reflection on the virtual side, which acts in all ways as a real piece. The pieces come in three types; red with red reflection, yellow with yellow reflection, and red with a yellow reflection (and vice versa, of course). On his turn a player can introduce a piece to the edge of the board, slide a piece of his colour or a dual piece or turn a dual piece 180 degrees. The aim of the game is to produce a line of 5 (but no more) pieces of his colour in any direction.
