FAQ
What is Sokoban?
Sokoban (Japanese for "warehouse keeper") is a classic transport puzzle video game invented by Hiroyuki Imabayashi in 1981 where the player pushes crates around a warehouse labyrinth onto designated target storage locations.
Why is Sokoban famous in computer science and AI?
Sokoban is computationally PSPACE-complete. Because boxes can only be pushed and never pulled, a single wrong move can permanently lock the board into an unwinnable deadlock state, making it a classic benchmark for AI search and heuristic planning algorithms.
What are the main causes of deadlocks in Sokoban?
A corner deadlock occurs when a box is pushed into an interior non-target corner formed by two adjacent walls. Line deadlocks occur when two adjacent boxes are stuck along a continuous wall without targets.
How do you control the keeper in this browser version?
Use the standard keyboard Arrow keys, WASD keys, or the on-screen directional touch pad on mobile devices.
