Sokoban

is a puzzle video game created in 1981 by Hiroyuki Imabayashi. In Sokoban, the player pushes boxes in a warehouse to get them onto storage locations. The game is viewed from a top-down perspective. Boxes can only be pushed, never pulled, and only one box can be pushed at a time. The principal challenge is planning moves correctly to avoid causing a deadlock, a situation where a box or the player becomes permanently trapped, making the puzzle unsolvable.

Its core mechanics became the foundation for a series of official releases. Imabayashi's company, Thinking Rabbit, released the first commercial version in 1982. After that first release, Thinking Rabbit and its licensed partners developed new titles until 2000. The game debuted internationally in 1988 with the U.S. release Soko-Ban. Falcon, a Japanese software company, acquired the Sokoban rights in 2001. Since then, new installments have been published either by Falcon under the Thinking Rabbit brand or by licensed partners.
