A game consists of
10 boxes, in which not more than 3 balls are allowed
for each box.
If all pins
are felled by first ball it is a strike and is marked
with a double line.
If all pins
are felled by first 2 balls it is a spare and marked
with a single line.
If all pins are felled
by 3 balls it is a ten box and marked by an X.
A strike permits you
to score ten plus a bonus of the pins felled by the
1st and 2nd balls of your next box.
A spare permits you
to score ten plus a bonus of the pins felled by the
1st ball of your next box.
