Judge

Judge is a game released for the Game & Watch on October 4, 1980, and was eventually ported to the Game Boy Color as part of Game & Watch Gallery 3. 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.

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