Judge

Judge is a game released for the Game & Watch on October 4, 1980, eventually ported to the Game Boy Color as part of Game & Watch Gallery 3 and also available to download for DSiWare. In both versions of the game, two characters each have a Hammer and must hit the opposing player with the hammer if his or her number is larger or run away if the number is smaller. Each character earns three points for hitting the opponent and two points for dodging the opponent's attack. If both characters have the same number on their placards, the character who attacks first gets the point, while the one who dodges first loses. If the player dodges by mistake, the opponent will receive two points. If the player hits the opponent by mistake, the opponent will hit the player back and receive five points. The winner is the first one to get 99 points.

In the Super Smash Bros. series, Mr. Game & Watch can use a move called Judge (Judgment in Super Smash Bros. Melee), where the number above his head decides the hammer's power.
