<p><b><u>The Game</u></b>: <blockquote><i>Try to reach the goal and accumulate as
many points as possible along the way! Each square in the path has a different
color. In order to cross a square, you must give up a chip of the same color as
the square. You will probably not have all the chips you need to reach the goal,
so to get them you must <u>choose among the proposals offered by the your
computer opponent</u>. Be quick, however, because after the first few rounds,
the trail will begin to burn. If the fire catches up to you, GAME OVER!!</i></blockquote>
</p>
<p><b><u>Scoring</u></b>:
<ul>
<li><b>Only your first game</b> will considered for the Hall of Fame - do your best!</li>
<li><i>+5</i> points for each square crossed</li>
<li><b><u>If you finish the game</u></b>, you also get:
<ul>
<li><i>+5</i> points for every non-black chip you have left</li>
<li><i>+1</i> point for every black chip you have left - there will be no blacks in your trail.</li>
<li><i>+50</i> points for reaching the end of the trail</li>
