All ten.
The objective of Bowling is to knock down and many pins as possible.
A bowling ball is a ball that is used in the game of bowling, where you roll the ball down an aisle and try to knock down as many pins as you can.
Knock down as many pins as possible.
You have to knock down ten pins in two tries to get a spare.
Assuming 10-pin bowling, if you knock all the pins down in one frame with one ball (a strike), you get 10 points plus the number of pins you knock down with your next two balls. If you knock all the pins down in one frame with two balls (a spare), you get 10 points plus the number of pins you knock down with your next ball.
All of them...
The object is to knock down as many pins as possible, the object is to get a strike, meaning knocking down all of the pins, If you don't knock them down on the first try, then you have the chance to pick up the spares, the person with the most points at the end wins.
That depends on how heavy your bowling ball is. If it is a 6 pound ball, it will not knock down as many pins as you would want it to. If you had a 14 pound ball, chances are you will knock down more pins with a heavier bowling ball.
The scoring for a strike in bowling is 10 plus the number of pins you knock down on the next two deliveries. If the first of those deliveries is another strike, you would get another 10. You would add to that (20) the number of pins you knock down on your next delivery. For example, if you knocked down 7 pins you would get 27 for the first strike (10 + 10 + 7) and for the second strike you would get 10 + 7 + the number of pins you knock down on your next delivery.
