The mining minigame is a
match-three style game. The goal is to match three or more icons (representing rocks in this version of the game) in a long chain, thereby clearing the way for special ore and gems to fall to the bottom and be collected. You have a time limit that ticks away; matching tiles add time back to the time limit. Each vein of ore (for instance, copper ore, rich copper ore, iron ore, etc.) has a different board shape and difficult level associated with it, but remains the same matching game throughout.
While you are matching tiles, beware. Brown blocks cannot be matched with anything, and can only be destroyed by dropping it to the bottom of the game board. Locked tiles (normal tiles with a lock on them) can't be destroyed or shuffled, but can be unlocked by matching them with other tiles in a regular chain. Star tiles act as wild-cards that you can match with any other tile in a chain.

There are several types of power-ups that can be used in the mining mini-game:
- Star Circle: A small circle with a falling star, using this power-up will create star tiles on the board.
- Dynamite: A circle with red dynamite, this power-up will destroy several nearby tiles.
- Shuffle: A circle with a tornado, the shuffle will randomly move tiles around on the board.
- Explosion: A circle with a small explosion in the middle, this power-up will destroy some random tiles on the board.
