<title>Introduction</title>

<para>
The first sokoban game was created in 1982 by Hiroyuki Imabayashi at
the Japanese company Thinking Rabbit, Inc.  <quote>Sokoban</quote> is
Japanese for <quote>warehouse keeper</quote>.  The idea is that you
are a warehouse keeper trying to push crates to their proper locations
in a warehouse.
</para>

<para>
The problem is that you cannot pull the crates or step over them. If
you are not careful, some of the crates can get stuck in wrong places
and/or block your way.
</para>

<para>
It can be rather difficult just to solve a level. But if you want to
make it even harder, you can try to minimize the number of moves
and/or pushes you use to solve the level.
</para>

<para>
To make the game more fun for small kids (below 10 years or so), some
collections with easier levels are also included in &skladnik;. These
are marked <emphasis>(easy)</emphasis> in the level collection menu.
Of course, these levels can be fun for adults too, for example if you
don't want to expose yourself to too much mental strain.
</para>
</chapter>

<chapter id="how-to-play">
<title>The Game</title>

<para>
The objective of the game is to push all the red gems to the goal
squares, which are marked with green glassy round things on the floor.
</para>

<para>
Use the cursor keys or the mouse to move about. If you move onto a gem
using the cursor keys or the &MMB;, and there is nothing blocking it on the opposite side, then you
will push the gem.  It isn't possible to pull the gems, so if you push
a gem into a corner it will be stuck there. You cannot step over the
gems either, so you can also get trapped in a part of the maze by
blocking the way with gems.  Also note that it isn't possible to push
more than one gem at a time.
</para>

<para>
If you notice that you have moved the gems in such a way that the
level is impossible to solve, then you can always use the undo feature
to go back to a position where the mistake has not yet been made. You
can of course also restart the level from the very beginning.

<title>Loading external levels</title>

<para>
&skladnik; has the ability to load external sokoban levels from text
files.  You can load levels using the <menuchoice><guimenu>Game</guimenu>
<guimenuitem>Load Levels…</guimenuitem></menuchoice> menu item, or by
specifying the level file &URL; as a command line argument when starting
&skladnik; from a shell.
</para>

<para>
The external levels must be defined using the standard characters
shown in the table below. If the file contains more than one level,
the levels should be separated by blank lines. The file may also
contain text between the levels.
