Sokoban is a puzzle game
in which the object is to move
all the packing cases into the storage
area. You can only
move the packing cases by pushing them, and since they are large
, you can only push them one at a time.
Also, you cannot climb or jump over them. To succeed you must be very careful
not to get cases into position
where they cannot be moved. For example, pushing a case into a corner
or two cases adjacent to each other against a
wall will ruin your game.
Slash'EM and the latest version of Nethack have an optional Sokoban branch. Since there is no way to start a level
again if you mess it up, you are permitted to "cheat" in various ways, but this is bad for your luck.
