<para>
Once a round is started, the players do not stop moving forward (unless the game
is paused).  All you have to do is avoid crashing by changing your players
direction. Additionally you can try to hinder your opponent.  For this it is
possible to increase the velocity by pressing your accelerator key.
</para>

<para>
A round starts when all human players press a direction key. The initial moving
direction is then in this direction.
</para>

<para>
If you want to interrupt playing, select
<guimenuitem>Pause</guimenuitem> from the <guimenu>Game</guimenu> menu
or hit the keyboard shortcut (see section <link linkend="keys">Default 
Shortcuts</link>).  Additionally the game is paused when the game loses the
keyboard focus, &eg; when switching to an other window.
</para>

<para>To continue the game, select the menu item
<guimenuitem>Pause</guimenuitem> again, or the keyboard shortcut.  The
game will also continue if the human players press one of their direction keys.
But be careful, your player switches to this direction immediately.
</para>


<para>A game consists of several rounds, and ends if a player has at least
nine points, and additionally two more points than the opponent. The current
score is always displayed in the status bar.
</para>

<para>
You can change the difficulty level of the game using the game menu item or
the select box on the status bar. The difficulty influences the speed of the
game and the computer player.
</para>
</sect1>

<sect1 id="computerplayer">
<title>The Computer Player</title>

<para>
You can play against a computer. The difficulty level of the game influences the 
intelligence of the computer player.
</para>
<para>
At low levels the computer doesn't care about the opponent and just moves
around. At higher skill levels the computer tries to hinder the opponent when he
comes near.
</para>
</sect1>

<sect1 id="using-keyboard">
<title>Using the Keyboard</title>

<para>
Each player has five keys. Four keys for changing the direction and one to
accelerate.
</para>

<para>
The direction keys do not have to be held down. Simply press them once to
change
the direction of your player.
</para>

<para>
Acceleration only occurs while the acceleration key remains depressed.  When you
release the acceleration key, velocity returns to normal.
</para>

You can alter the keys using the shortcuts option in the <link
