         <para>&kblackbox; is a nice logical game, inspired by the &Emacs; blackbox game. A major part of this help file is based on the original &Emacs; help.</para>
 
 <para>&kblackbox; is a game of hide and seek played on a grid of boxes. The computer has hidden several balls within this box. By shooting beams into the box and observing where they emerge it is possible to deduce the positions of the hidden balls.</para>
 <para>The fewer beams you use and the quicker you are to find the balls, the better (the lower) your score.</para>

 <para>Use lasers and place balls and markers on the game board to deduce the position of the hidden balls inside the black box.</para>
 <para>
         The game starts as soon as you use the first laser. Before that, the time is not running and no point will be count for the score.
 </para>
 <para>The cursor can be moved around the box with the standard cursor movement keys or the mouse. Switching of lasers or marking of black boxes is done with the &LMB;, or by pressing the <keycap>Return</keycap> or &Enter; key.</para>
 
 <para>You can also drag and drop the balls and the markers with the mouse.</para>
 
 <para>You can mark the fields where you think a ball cannot be, too. Just press the &RMB;. It often helps you to find an area where a ball could possibly
 be. To clear any marks, press the same key or mouse button again.</para>
 
 <para>When you think the configuration of balls you have placed is correct, press the <guibutton>Done!</guibutton> button. You
 will be informed whether you are correct or not, and be given your score.
 </para>
 <para>
         If you placed any balls incorrectly, the right solution will be displayed.
 </para>
 
 <para>
         The score increases with the time (1 point per second) and with the use of lasers: 3 points if the laser beam hits a ball or exits at the entry point and 9 points if it exists at another entry point.  If you make a mistake, the score is set at the end of the game to 999, which is the maximum score.

 <para>You have to find balls hidden in the black box. Your means are limited - you can just fire lasers which are around the box. There are three possible outcomes for each beam you send into the box: </para>
 
 <anchor id="detour"/>
 <variablelist>
 
 <varlistentry>
 <term>Detour</term> 
 <listitem><para>The beam is deflected and emerges somewhere other than where you sent it in. On the playfield, detours are denoted by matching pairs of numbers - one where the beam went in, and the other where it
 came out.</para></listitem>
 </varlistentry>
 
 <varlistentry>
 <term>Reflection</term>
 <listitem><para>The beam is reflected and emerges in the same place it
 was sent in. On the playfield, reflections are denoted by a special sign.</para></listitem>
 </varlistentry>
 
 <varlistentry>
 <term>Hit</term>
 <listitem><para>The beam strikes a ball and is absorbed. It does not
 emerge from the box. On the playfield, hits are denoted by a special sign.</para></listitem>
 </varlistentry>
 </variablelist>
 
 <para>The rules for how balls deflect beams are simple and are best shown by
 example.</para>
 
 <para>As a beam approaches a ball it is deflected ninety degrees. Beams
 can be deflected multiple times. In the diagrams below, the dashes
 represent empty box locations and the letter <guilabel>O</guilabel>
 represents a ball. The entrance and exit points of each beam are marked
 with numbers as described under <link linkend="detour">Detour</link>
 above. Note that the entrance and exit points are always
 interchangeable. <guilabel>*</guilabel> denotes the path taken by the
 beam.</para>
 
 <para>Note carefully the relative positions of the ball and the ninety
 degree deflection it causes.</para>

 <para>
 As mentioned above, a reflection occurs when a beam emerges from the same
 point it was sent in. This can happen in several ways:
 </para>

 </screen>
 
 <para>In the first example, the beam is deflected downwards by the upper
 ball, then left by the lower ball, and finally retraces its path to its
 point of origin. The second example is similar. The third example is a
 bit anomalous but can be rationalized by realizing the beam never gets a
 chance to get into the box. Alternatively, the beam can be thought of as
 being deflected downwards and immediately emerging from the box.</para>
 
 <para>A hit occurs when a beam runs straight into a ball:</para>

 <para>Be sure to compare the second example of a hit with the first
 example of a reflection.</para>
