A game of ten-pin bowling is divided into ten
rounds, "frames". In a frame, each player is given
two opportunities to knock down the skittle targets, "pins".
If the first ball knocks down all ten pins, it is called a
"strike" and the frame is completed.
Then the player rolls a second
ball and if the remaining pins are knocked down, it is called
a "spare." There are bonuses for removing all the
pins. If there is more than one player scheduled on a lane,
play passes to the next player until all players have completed
the frame.
Then play continues with the
next frame. The final or tenth frame of a game may involve
three balls.
The ten pins are usually
automatically set by machine into four rows which form an
equilateral triangle where there are four pins on a side.
There are four pins in the back row, then three, then two,
and finally one in the front at the center of the lane.
In order to count, a pin
must be knocked over entirely. In unlucky circumstances, a
pin may wobble furiously, yet come to rest upright, thus not
being scored. Alternatively, the pin may wobble furiously
and the automatic pin machine picks up the pin as it wobbles.
Tweaks to get the
10-pin to fall
Solid 10-pin
Normally you will get a solid
10-pin when you hit the pocket a bit high. The 3-pin will
wrap around the 10-pin, leaving it standing unharmed.
Move a couple of inches backward
on the approach, resulting in walking a bit faster on the
approach and thus throwing the ball a bit faster. The ball
will skid a bit more due to this.
Grab another ball, which has
a lesser finish than the ball you are bowling with at the
moment.
Move some boards to the left
on the approach, but keep your target as it was. This will
result in hitting the pocket a bit lower.
Change your release at the
foul line in such a way that you will keep your hand more
behind the ball and thus lesser turning it. This will also
result in a less strong finish.
Throw your ball less far
onto the lane. The ball will have to travel further towards
the pins, losing more force and thus finishing weaker.
