<title>What is &kblackbox;?</title>

<para>&kblackbox; is a superb :-) graphical logical game, inspired by
the <application>emacs</application> blackbox game. A major part of this help
file is based on the original <application>emacs</application>
help. </para>

<para>&kblackbox; is a game of hide and seek played on a grid of
boxes. Your opponent (the Random number generator, in this case) has
hidden several balls within this box. By shooting rays into the box and
observing where they emerge it is possible to deduce the positions of
the hidden balls. The fewer rays you use to find the balls, the better
(the lower) your score.</para>

<chapter id="game-description">
<title>Game Description</title>

<para>In the first part of this section a description of the game board
will be given.  The second part deals with user interaction with the
game board and finally in the third part the actual game rules are
explained.</para>

<note><para>The names of colors are used just for identifying the

:-). </para></note>

</sect1>

<sect1 id="user-interaction">
<title>User Interaction</title>

<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 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 (blue or brown) press the
&LMB;. Brown marks cannot overwrite blue
marks. This way you cannot erase the blue marks (guessed balls) by accident when
playing with the &RMB;. </para>

<para>When you think the configuration of balls you have placed is
correct, press the &MMB;. You
will be informed whether you are correct or not, and be given your
score. Your score is the number of letters and numbers around the
outside of the box plus five for each incorrectly placed ball. If you
placed any balls incorrectly, they will be indicated with red fields,
and their actual positions indicated with cyan fields.</para>

</sect1>

<sect1 id="game-rules">
<title>Game Rules</title>

<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 ray you send into the box: </para>

<anchor id="detour"/>
<variablelist>

<varlistentry>
<term>Detour</term> 
<listitem><para>The ray 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 ray went in, and the other where it
came out.</para></listitem>
</varlistentry>

<varlistentry>
<term>Reflection</term>
<listitem><para>The ray is reflected and emerges in the same place it
was sent in. On the playfield, reflections are denoted by the letter
<guilabel>R</guilabel>.</para></listitem>
</varlistentry>

<varlistentry>
<term>Hit</term>
<listitem><para>The ray strikes a ball directly and is absorbed. It does not
emerge from the box. On the playfield, hits are denoted by the letter
<guilabel>H</guilabel>.</para></listitem>
</varlistentry>
</variablelist>

<para>The rules for how balls deflect rays are simple and are best shown by
example.</para>

<para>As a ray approaches a ball it is deflected ninety degrees. Rays
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 ray 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
ray.</para>

<para>Note carefully the relative positions of the ball and the ninety
degree deflection it causes.</para>

</screen>

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

<screen>
  - - - - - - - -         - - - - - - - -          - - - - - - - -
  - - - - O - - -         - - O - O - - -          - - - - - - - -
R * * * * - - - -         - - - * - - - -          O - - - - - - -
  - - - - O - - -         - - - * - - - -        R - - - - - - - -
  - - - - - - - -         - - - * - - - -          - - - - - - - -
  - - - - - - - -         - - - * - - - -          - - - - - - - -
  - - - - - - - -       R * * * * - - - -          - - - - - - - -
  - - - - - - - -         - - - - O - - -          - - - - - - - -

</screen>

<para>In the first example, the ray 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 ray never gets a
chance to get into the box. Alternatively, the ray can be thought of as
being deflected downwards and immediately emerging from the box.</para>

<para>A hit occurs when a ray runs straight into a ball:</para>

<screen>
  - - - - - - - -         - - - - - - - -          - - - - - - - -
  - - - - - - - -         - - - - - - - -          - - - - O - - -
  - - - - - - - -         - - - - O - - -        H * * * * - - - -
  - - - - - - - -       H * * * * O - - -          - - - * - - - -
  - - - - - - - -         - - - - O - - -          - - - O - - - -
H * * * O - - - -         - - - - - - - -          - - - - - - - -

  - - - - - - - -         - - - - - - - -          - - - - - - - -

</screen>

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