<h2>Scoring</h2>
<p>
The contest is made up of multiple <em>categories</em>. Each
category is worth one point toward the total score; the percentage
of the total points held by your team is the percentage of one
point your team has for that category. The team that has 30% of
the points in each of five categories has 1.5 points, whereas the
team that has 80% of the points in only one category has 0.8
points.
</p>
<p>
There are two kinds of categories: <em>flags</em>,
and <em>puzzles</em>.
</p>
<h3>Flags</h3>
<p>
Flag categories are challenges with a notion of a <em>winner</em>
or <em>service availability</em>. In these categories, the
flag-holder (the winner, or each team with a running service)
makes 1 point per minute for as long as they hold the flag. If
there is a single flag-holder, and the flag changes hands, a point
is awarded to the new winner at the moment the flag moves.
</p>
<h3>Puzzles</h3>
<p>
Most of the categories come in the form of
multiple <em>puzzles</em>: for each puzzle presented, a key
(answer) must be found to recieve the amount of points that puzzle
is worth. Any team may answer any puzzle question at any time. A
new puzzle is revealed when a team correctly answers the
highest-valued puzzle in that category.
