Sokoban is a game invented by a Japanese company, "Thinking Rabbit". Essentially, it's the Block Puzzle of all Block Puzzles.The idea is simple: Push all of the blocks inside a maze on their target positions, but there are three rules that make it tricky:
- You cannot pull blocks; you can only push them.
- You cannot push more than one block at a time.
- Your character can't just move anywhere; to push a block, he has to have a route to the square behind it.
Sokoban provides examples of:
- Back Tracking: Since you can only push one block at a time, you will have to traverse the map multiple times. This is amplified in some layouts (e.g. Level 20), where you need to traverse the entire level to get a box around a corner.
- Block Puzzle: The ultimate.
- Follow the Leader: Aside from thousands of straight remakes, the basic mechanics have themselves became a standard for most puzzle games with blocks.
- Lost Forever: You cannot retrieve a block pushed in a corner, or next to an edge wall. If one of the target squares is right there, it's all fine, but if not, then you need to undo or restart.
- Nintendo Hard: Especially in higher levels.
- Timed Mission: Versions count the number of seconds, moves or pushes.
- Unwinnable by Mistake: Very rarely, some poorer clones/remakes feature levels that are unsolvable from the very start.
