Clear the board by removing every tile in matching pairs.
- Tap a free tile to select it, then tap another matching free tile to pair them.
- A tile is blocked if another tile sits on top of it, or if it is squeezed from both left and right.
- Hint briefly highlights one possible pair you can take.
- Shuffle keeps the same layout but randomizes which faces appear on tiles.
When no tiles are left, you clear the level.
