If you think chess is hard, you better try the strategy game called one of the best by Mensa members worldwide! The object sounds simple enough: move your pawn from your side of the board to the other before your opponent does. But instead of making a move, you can use your turn to place a wall in their way. But remember; you only have 10 walls to work with...and every one counts! Parent's Choice Gold award winner. Measures 10 1/2 x10 1/4 x 1 1/2 . 2 or 4 players. Ages 8 and up.
