[Note: The Sokoban map did not change in 3.4.0 or 3.4.1, and this spoiler
accordingly remains valid.]

      □ Level 1, version A
      □ Level 1, version B
      □ Level 2, version A
      □ Level 2, version B [Ed: or an alternate version by Jukka Lahtinen]
      □ Level 3, version A
      □ Level 3, version B
      □ Level 4, version A [Ed: or an alternate version by Jukka Lahtinen]
      □ Level 4, version B

Boulders are represented by capital letters (A, B, ...), to be able to
reference them. To refer to a position on the map, the co-ordinates shown on
top and on the left of the map in (X,Y) format are used. For example, the
starting position on level 1, version A, is (7,5).

If you are told to finish several boulders, you should finish them in the
order in which they are mentioned.

There are other solutions, for sure. Quite possibly there are faster
solutions. I haven't counted the number of moves needed for any of the below
solutions. If you have faster solution, don't hesitate to use it.

Note that the Sokoban levels have other internal numbers than the ones that
are used below, but starting with level 4 is quite confusing, even if you are
moving up, not down. Here, level 1 is the first level you'll see in your game
and level 4 is the last one, with the reward.

A general tip: after you've finished a level, push all boulders that are left
into corners where they are harmless. You wouldn't want yourself to
accidentally move them when going back later and lock you in. Also, there
might be something lying underneath them.
