<H2>Instructions</H2>
<H4>
The objective of this puzzle is to connect the points with lines in 
the uncompleted puzzle so it matches the completed puzzle. You can not draw 
over existing lines. You first choose a starting point, then click on a 
different valid point (see completed puzzle) to connect 
both points with a line.  Pick another valid point from the last point 
you just picked and connect those two points. Repeat this process over and 
over again until all lines are drawn to match the completed puzzle.
<P>
Keep your eye on the status line below the puzzles, this will give you 
feedback while you are trying to solve the puzzle.
<P>
If you come to a point where no lines can be drawn, you lose.  Press the 
restart button and give it another shot.
<P>
There are three puzzles to choose from, so go have some fun!!! (If you 
select another puzzle and nothing happends, move the mouse around and 
this should help.

<H2>Winner Log</H2>
Due to time limitations this feature was not implemented.  The plan was 
to have a winner log to keep track of the "ten best times" When you 
start to solve the puzzle the timer (beside the status line) would keep 
track of your time.  When you completed the puzzle successfully, your 
time would be compared with the times in winner log.  If your time was 
better than at least one of the ten times in the winner log, your 
information would be added.
<P>
To do this we designed a server to listen for the puzzle client. (If 
your score was to be added) The server would keep track of the puzzle 
players name, date solved, and time it took to solve.  We thought it 
would be interesting for people to compete others from all around the 
world.
