How to play:
- Tap a tile to select it. Tap another tile of the same type to make a match.
- A tile is "free" when its left or right side is not blocked by another tile.
- Clear all tiles to complete the stage and earn coins.
- Some tiles are face-down — tap to reveal them first.
- Rock tiles cannot be selected. They break when an adjacent tile is matched.

Items (purchasable with coins):
- Undo — Restore the last matched pair.
- Hint — Highlight a matching pair on the board.
- Shuffle — Randomize all remaining tile positions.
- Magnet — Automatically find and remove a matching pair.
