10th Frame is a ten-pin bowling simulation game published by Access Software in 1986.
It was released for the Amstrad CPC, Atari ST, Commodore 64, IBM PC compatibles, MSX, and ZX Spectrum.
A small zone at the top determines if the player makes an error, exaggerating any spin.
Zzap!64 awarded the game 85% in issue 22, calling it "another slick and extremely well programmed Access sport simulation".
[1] Your Sinclair gave the ZX Spectrum conversion 7 out of 10, stating that "10th Frame requires a lot of skill and is a pretty good simulation".
