A friend on Facebook found a copy of the Sinclair User Annual 1983 which had one of them in.
(Update: I called this game "Beancup" but I've just found out (Nov 2016) it's called Oware amongst other names.) I didn't always buy the magazines that published my games, because that would eat into the money I'd made, so it was quite exciting to see my work from so many years ago revived again. I didn't have a printer, so unlike many of the other listings this one was typeset.
Some things strike me about this:
- no function names, you just GOSUB a line number
- line numbers!
- I'm surprised how compact it is - a two player game, plus the computer's strategy in just a few lines
Update: I was searching my blog archives for the word Sinclair and I came across this post about mobiles and gaming. What is interesting is the article I link to which talks about the potential for mobile (what we now call) apps. This was pre iPhone and Android app stores, so presents a "historical" perspective before things all changed.
