Explain Ten-Pin Bowling Scoring in Plain English

The screen updates after every ball and the running total jumps in ways that make no sense until someone explains strikes and spares properly. This walks through a full game frame by frame, so next time you can mark your own card and know exactly why 300 is perfect, not 100.

Explain how ten-pin bowling scoring works: how a strike and a spare carry pins forward into the next frame, why the tenth frame gets extra balls, and why a perfect game is 300 rather than 100. Walk through one full ten-frame game as a worked example, showing the running total build up frame by frame, not just the final number. Keep the maths visible enough that the reader could mark their own scorecard afterwards.
