How a bowling score works
Each frame is worth the pins you knock down, plus a bonus. A strike (X) is ten plus the next two throws. A spare (/) is ten plus the next one. Everything else is added as it falls, and a miss is marked with a dash. The tenth frame allows the extra throws that the bonus needs.
Type the frames separated by spaces, using X for a strike, a slash for a spare, a dash for a miss and digits for single throws. A perfect game is X X X X X X X X XXX and scores 300.
| Game | Score |
|---|---|
| X X X X X X X X X XXX | 300, the perfect game |
| 9- 9- 9- 9- 9- 9- 9- 9- 9- 9- | 90, nine pins every frame |
| 5/ 5/ 5/ 5/ 5/ 5/ 5/ 5/ 5/ 5/5 | 150, all spares |
| X 9/ X 9/ X 9/ X 9/ X 9/X | 200 |
