Sokoban means warehouse keeper in Japanese. Sokoban is a free puzzle game requiring logical thinking and puzzle-solving.

The goal is to push boxes to their correct destinations (the designated target squares) in a crowded warehouse. The player controls the "man" and the man can only push boxes, and only one at a time. You cannot push two or more boxes at once. The challenge comes in having to think ahead; in the process of moving the boxes, you might accidently create unsolvable positions. Players will soon learn that this is the main obstacle in solving problems. Advanced players also try to find shorter and shorter solutions, measured in man moves and boxes pushes.

This Widget version features 50 puzzles that you can solve with your brain, and a keyboard or the mouse. The mazes range from very simple to extremely difficult ones requiring many hours of brain work.

The game was invented in Japan. The original program was written by Hiroyuki Imabayashi. Since then, several versions have been written for most personal computers.
