Game & Watch Gallery 3 is the third game in the Game and Watch remake series for the Game Boy line. It included five minigames playable from the start and three more unlockables; all of which could be played in either Classic Mode with the original Game & Watch characters or an updated Modern Version featuring Mario franchise characters.
- Judge - A reaction game where the player with a number of equal or higher value attempts to hit the other, while the player with the lower number tries to run away.
- Flagman - In Game A, copy the pattern shown by Flagman. After copying the pattern correctly, another step is added for the next round. In Game B, Flagman only shows one number; however, the time to react to this number shortens over time.
- Lion - A game where the player must control lion tamers on either side of a cage to keep the lions inside.
- Spitball Sparky - A breakout-like game, break all the blocks to go up a level.
- Donkey Kong II - In this re-release of the game with the same name, Donkey Kong Jr. must hit four keys up the screen in order to free his father from chains.
