In the early part of the 1990’s there was a Windows game that I was playing on my father’s computer. I remember it quite fondly and recently found it in the Internet Archive. The game was Jewel Master by Peter Siamidis and it can be played online. I didn’t know it at the time, but it’s apparently a clone of a Sega game called Columns. Go figure. Even though I enjoyed it quite a lot I wasn’t quite good at it, and I’ve wondered what a good player would do. After my previous success with coded crosswords, I decided to give AI another go.
