The mini-game is basically a Sonic-themed version of classic Minesweeper, where the player must clear the ground containing hidden "mines" without detonating any of them. Unlike most minigames, this features single player only, although the player can transfer it to another Game Boy Advance with no cartridge inserted.
Knuckles the Echidna is the only playable character in this mini game.
- Due to a design oversight, there is no way to exit the minigame once it is started. However, no data is lost by turning off the system while playing Mine Hunt.
