In the UK on Acorn's old RiscOS machines; RiscOS was the first multitasking GUI, and it took a bit of getting your head around as a programmer. Factor into that the fact that the ARM chips were RISC processors - ie. they had a reduced instruction set, and were also 32 bit processors not the more familar 16 or 8 bit; then people found it a bit hard to get into. Most people didn't want to jump straight into assembler, and C compilers were thin on the ground at the time.

The Patience which went out with RiscOS (built into ROM !!) was coded entirely in BBC Basic, and was 100% RiscOS compliant in it's multi-tasking structure - therefore if you wanted to program for the RiscOS desktop, you pretty much has to start there. It really did give a great insight into how the whole thing worked.

The Game itself was pretty much the standard Windows Klondike variant.
