A tactical number game by Reinhold Wittig. The game uses a very large roll-out board, showing fields with numbers. Players roll four dice and mentally must calculate a total using any mathematical relationships possible. The try to create such totals to match to spaces on the board in order to place stones that will both capture the point-value pieces and block off others' movements. Similar in concept to Wittig's Hakahana, this game is like that one on steroids as it adds a very nice placements and tactical element to the math.
