A tile-matching puzzle game inspired by Mahjong Solitaire. Tap two free tiles of the same type to clear them from the board. Complete each stage by removing all tiles.

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.
