One of the best, seemingly simple strategic game of obstruction and construction. Players must add a wooden piece to the board in turn. But two same colour pieces or same height pieces cannot touch. And if Player 1 places their blue piece vertical, Player 2 must place their blue piece horizontal! With limited space on the board, the player who gets blocked first, loses! AARGHHH. Comes with 1 wooden playing surface, 10 wooden blocks, instructions.
