is a DSiWare game based on the Game & Watch LCD toy of the same name. Unlike many other Game & Watch games, it can be played with either one or two players. Two characters holding mallets stand opposite each other. Numbers appear on two large signs above them (between 1 and 9). If your number is the same or higher than your opponent's, whack them with your mallet. If it's lower, dodge out of the way. The first player to react scores a point. The first player to 99 points wins.
