The game:

"Sokoban" is a puzzle game invented in Japan 1982 by Hiroyuki Imabayashi. The rules are very simple but the game itself is not.

The Rules

The object of the game is to push boxes to specially marked positions in a level. The boxes can only be pushed, never pulled, and only one can be pushed at a time. The player can only move on "free" (= no wall and no box) fields.

A level is solved if all boxes have been pushed to specially marked positions.
One field can just be occupied by only one of the following levelelements at a time: the player, a box, a wall

Just start the game. You easily will learn the rules by playing the game.

The computer will help you in positions where you lost the possibility to solve the level (for example, if you pushed a box in a corner) by showing you the message that the level isnt solvable anymore.

Note: Recognizing positions that are unsolvable is very difficult. Hence the computer just shows this message for some kinds of unsolvable positions.
