Sokoban
Sokoban is a classic puzzle game invented in Japan. The original game was written by Hiroyuki Imabayashi. In 1980 it won a computer game contest. Mr Hiroyuki Imabayashi is president of the company Thinking Rabbit Inc. in Japan. The game is Copyright 1982 Thinking Rabbit. Over the years many versions for all platforms have been made and new levels are created all the time.

Sokoban means warehouse keeper in Japanese. The object of the game is to push boxes (or balls) into their correct position in a crowded warehouse with a minimal number of pushes and moves. The boxes can only be pushed, never pulled, and only one can be pushed at a time. It sounds easy, but the levels range from very easy to extremely difficult, some takes hours and even days to figure out. The simplicity and elegance of the rules have made Sokoban one of the most popular logic games.
