To remove tiles, find and select two identical tiles from the suits of Bamboos, Circles, Characters, Winds, or Dragons.
A tile is considered open if it has no tile directly to its left, right, or above it.
For the Flowers and Seasons tiles, any two tiles from the same group can be paired and removed.
If you find yourself stuck, you can use the "Hint" or "Shuffle" features to reveal new possible moves
