As a bowling expert, I can tell you that a standard game of bowling consists of
10 frames. Each frame allows a bowler two opportunities to knock down all the pins. If all the pins are knocked down on the first roll, it's called a
strike, and the frame is over. If not all pins are knocked down, the bowler gets a second roll to knock down the remaining pins. If all the pins are knocked down in two rolls, it's called a
spare. The score for each frame is calculated by adding the number of pins knocked down in both rolls.
