CRICKET RULES

Cricket is likely the most popular variant of
darts played in the United States.  The
object of Cricket is to hit the slots 15-20
inclusive and the bullseye 3 times each while
scoring more points than your opponent.  

SCORING

The first player to hit any of the
aforementioned slots 3 times before their
opponent can earn points with further hits on
the same slot.  When both players have hit a
slot 3 times, no points can be earned by
either player with further hits on that slot.

A throw that lands in the singles area is
worth 1 hit; the doubles area 2 hits; and the
triples area 3 hits.  An outer bullseye
counts as 1 hit while an inner bullseye
counts as 2 hits.

On the scoreboard, a single hit is denoted by
a slash; 2 hits by an X; 3 hits by an X
inside a circle.

SCORING EXAMPLE

As an example, let's say player A has 2 hits
on the 20 slot while player B has 1 hit.  In
player A's next turn, he throws a double 20,
then a single 20.  The double 20 counts as 2
hits and brings the total hits for the 20
slot to 3.  Since player B has not yet hit
the 20 3 times, player A's final throw of the
turn, a single 20 worth 1 hit, earns him 20
points.

A hit on the bullseye that earns points is
worth 25 points while a double hit on the
bullseye that earns points is worth 50
points.

WINNING

Players alternate turns by throwing 3 darts
each.  The game ends when one player has hit
each slot in 15-20 inclusive and the bullseye
3 times while also having more points than
their opponent.

DRAWS

In this implementation, ties or draws are not
possible.  If both players have hit all
required slots 3 times but have equal score
(even 0), the player who hit all the required
slots first is declared the winner.
