The Game Bots are arcade machine-like robots that run the Mini-Game Shop in Wario Land 4. They allow Wario to play mini-games at the shop for a chance to win some medals. There are three different colored Game Bots, each hosting a different mini-game. The currency used in the Mini-Game Shop is points that Wario obtains in levels. Normally, the price for playing a mini-game is 5000pts, but until Wario completes the Entry Passage, the cost is discounted to 2000pts. If Wario gets a decent score in any of the three mini-games, he will be awarded medals, which can then be spent at the Item Shop. All items from the Item Shop can be purchased to assist Wario in defeating a boss.
The following table displays which of the three mini-games each Game Bot hosts, along with the nature of that Game Bot.
