Game Guy

"Step right up! It's time for a green!"

- Game Guy

Game Guy is a Shy Guy in Mario Party 3 who sports a bow tie and a natural showman's attitude. He runs a game show-esque gambling event that players must play when they land on his space. Players can usually double their coins or lose all coins, though they can risk their money for higher multiples. The games all revolve on luck. He owns four mini-games: Game Guy's Lucky 7, Game Guy's Magic Boxes, Game Guy's Roulette and Game Guy's Sweet Surprise. If a player lands on his space, Game Guy holds one of his mini-games. Players can also call Game Guy on themselves or other players by using the Lucky Charm without needing to land on his space.

The player can unlock the door where Game Guy is found, in the Game Guy Room, to be able to play his games at any time. Here, the player is given 10 coins and can bet any amount of coins held, up to 100 coins. The goal is to reach 1,000 coins, but losing all of them ends the game. Winning this challenge unlocks the rare mini-game Mario's Puzzle Party Pro, a modified version of Mario's Puzzle Party.
