How to play
Remove all tiles with a ring (cores) to clear the level.
- Place the piece anywhere it fits.
- Slide all tiles in one direction. Cores do not move.
- Two tiles of the same color and value that meet merge, and the value doubles.
- A same-color group whose values add up to 5 or more is removed. The tiles then slide again, which can start a chain.
- After each slide, gray stones appear on the side the tiles moved away from. More stones come at higher levels.
- Stones do not match or merge. A match removes the stones next to it.
- A chain of 2 or more gives a tap. A tap removes any group of 2 or more.
- The game ends when no piece fits.
