About Klotski

Klotski is a classic sliding block puzzle related to China's Huarong Dao tradition. The challenge is not speed, but carefully creating space so the largest block can escape.

Click a block, then click an adjacent open space or use the move buttons shown by the game logic to slide it one step.

Origin and background

Sliding block puzzles became popular because they create large challenges from very small rule sets. Klotski is one of the best-known forms: a rectangular board, several blocks, and one important exit.

The puzzle is often associated with Huarong Dao, where the large block represents a key character escaping through a narrow route.

How to play

Select a block and slide it into an adjacent empty space. Continue rearranging blocks until the largest block reaches the exit area.

The best approach is not to move randomly. First make room near the central block, then rotate the smaller blocks around it.

Rules

Slide blocks into empty spaces.
Move the main block to the target exit.
Blocks cannot overlap or leave the board.

Beginner tips

Create room around the main block first.
Move small blocks into parking positions when they help open the exit path.
Avoid blocking the only exit path.

Common mistakes

Moving the main block before enough space has been created.
Pushing small blocks into positions that block the exit lane.
Undoing useful space just to make one immediate move.

Why it is still fun

Klotski is satisfying because progress is visible. A board that looks completely blocked can suddenly open after a few careful slides.

It rewards patience and planning more than fast reactions, making it a strong choice for thoughtful puzzle play.
