The game board is a kind of seesaw which can hold metal balls. Each player has four balls: - 2 small ones - a medium one (weighing twice as much) - a large one (weighing three times as much as the small ones. A player has to create an imbalance, the other player has to restore balance. If he or she fails to to so, the first player can do it and gain a point. In the basic game, five points win. There are several variants as well, some including a die which determines the amount of moves.
