What is Klotski / Huarong Dao?
A classic Chinese sliding-block puzzle based on the escape of the warlord Cao Cao after the Battle of Red Cliffs in Romance of the Three Kingdoms. Slide the large 2×2 block down to the exit gap at the bottom of the board.
How do I move a block?
Tap any block to select it, then tap one of the arrow buttons to slide it one step in that direction. A block can only move into empty space.
What's "par"?
The minimum number of moves needed to solve that puzzle, verified by an exhaustive solver. Try to match or beat it.
What does Hint do?
Shows the next correct move toward a solution, computed by the same solver used to verify every puzzle.
What's free vs. Pro?
The Classic puzzle and all 4 Easy puzzles are free. Klotski Pro unlocks the 14 Medium and Hard puzzles, plus the Hint system for every puzzle.
Is the app bilingual?
Yes — switch between English and 简体中文 anytime from the home screen.
