Zertz is a fast, dynamic game for two players. The game is played with five white, seven gray and nine black marbles and 37 round tiles. The tiles are used to assemble the board; the marbles are in a pool. Each turn you must place one marble on the board and then remove a free tile. The aim is to capture three white, four gray and five black marbles or two marbles of each color. To capture you must jump with a marble over another marble. It sounds easy, but both players play with the same marbles and the board gets smaller with every move. Thus, the players are forced toward a situation where every move is a crucial one. When you create a trap for your opponent at the wrong moment, you may find yourself caught in the trap. This international edition includes English rules. The game is for two players ages 10 and up. It takes about 15 minutes to play.
