Only the current version so far — new entries appear as the game ships updates.
Klotski (Huarong Dao) is the sliding-block puzzle where nothing is removed and nothing is added: you simply move pieces into the only empty space until the large 2x2 block can slide out through the gap at the bottom. Five layouts ship with the app, from a warm-up you can solve in a handful of moves to the famous packed classic.
