I really liked Zen Puzzle Garden back in the day. I spent a lot of time playing it when I ought to have been working on my PhD, and I even ended up writing a paper on it. [0]
It’s interesting that Gwern explicitly mentions ZPG as an inferior predecessor, because – for reasons I cannot clearly articulate or explain – I find it much more enjoyable to play than Samon. The player experience feels a lot more polished.
For a while, you could upload your own ZPG garden designs to the Lexaloffle BBS, where they would be playable on the web. I designed a few brutally difficult gardens, which were unsolved for years. Good times.
