Always a fun game to play. Played on a 7-1/2" handcrafted hardwood board with colorful one-inch marbles. Each player selects his 4 marbles of the same color. Alternating turns, place marble on board to get 3 in a row in any direction. Player B places his marbles to block his opponent's move. Variegated hardwoods assembled into beautiful, timeless game boards. A clear varnish finish is used to protect the wood.
