Introduction to Bowling


How we play?


How it work?
- Each time we play, it’s called a game
- Each game has 10 frames
- Each frame has 2 throws (10 pins)
- Frame is scored as the total number of pins knocked down during that frame
- 10 pins down knocked down in 1st throw Strike plus number of pins knocked down next 2 throws
- 10 pins down knocked down in 2nd throw Spare plus number of pins knocked down next throw
- If it’s your last throw, then, you get bonus round(s) for Strike and Spare instead
- Game score is the sum of the number of pins knocked down plus bonuses for strike and spare
