What is Sokoban?
Sokoban is a classic game invented in Japan. It's a very addictive strategy game in which the player, as a warehouse keeper, pushes boxes to their correct destinations in a crowded warehouse.
The trick in Sokoban is moving the boxes without getting them or the warehouse keeper stuck. Because boxes can only be pushed, not pulled, the warehouse keeper, or Sokoban in Japanese, has to be careful not to get them stuck against a wall or another box before they reach their destination.
Sokoban was written in the early '80's in Japan where it won a computer game contest. Sokoban and variations of it have since been written for many different operating systems.
