BARDARTS v1.1            

In the standard games of 301 darts, your aim is 
to reduce the starting score - 301 - to exactly 
zero. Darts in the inner bull score 50 and in the 
outer bull 25.  Darts in a sector score according 
to the sector number, unless they land in the outer 
'doubles' ring, when they score double the number, 
or the inner 'trebles' ring, when they score three 
times the number. The game must end with a 
DOUBLE that brings the score down to exactly 
0. (The inner bull counts as a double because it's 
double 25.) Each player throws three consecutive 
darts a session.
       
If your score drops below zero or one, then the 
entire session of darts thrown(1 to 3) is erased to 
previous session's score. For example, if the score 
is 20, you need a double 10 to win. If you throw 
a single 10 then a single 20, you are -10 or 'bust' 
and your score is 20 again. The number right above 
the dart board is the distance the dart thrown is 
from the center of bull. You can use this number 
when shooting for the bull to determine which player 
is closest to the bull. Keep in mind that red always 
goes first, so the player who is closest must choose
red. Hit space bar to reset game after determining 
which player is the closest to the bull's eye.
      
To simulate what might happen in a real game of 
darts, a dart that lands very close to a dart that is 
already on the board might fall from the dartboard.
