Ask HN: Any good examples of learning through games/puzzles, for adults?

Not really a full "game", but I found this picture-based Morse code trainer from Experiments with Google a fun and easy way to learn Morse code: https://morse.withgoogle.com/learn/

http://nandgame.com was posted on HN recently and I found it to be fun and educational: https://news.ycombinator.com/item?id=17508151

There's https://vim-adventures.com/ although I never really enjoyed it, it was a fun game for the first 15minutes.

So all Zachtronics games. Also Kerbal space program. Fantastic game, you'll learn about celestial mechanics, the basics of designing rockets (and if you keep playing, stuff like the Oberth effect and how to do a nice interplanetary Hohmann transfer )

Wanna learn history? Pick up some of the Paradox grand strategy games; Europa Universalis, Victoria, Hearts of Iron, Crusader Kings. A side effect is that you'll pick up a lot of geography by osmosis, which is in my experience, the easiest way to learn that subject - you're looking at maps and borders and terrain features constantly.

Wargaming is in general a good way to pick up information on historical topics. Most developers that are in that niche put a lot of effort into doing the research, and there is typically a lot of information baked into the in-game documentation at your fingertips, not to mention being a springboard for Wikipedia safaris.

My son loves Crusader Kings 2 (and EU3), and had such an easy time in his history class because of this. He knew the geography of Europe down cold.

He's currently digging into Hearts of Iron IV.

To be honest these grand strategy games aren't really my thing but I should give them a shot. Their systems just seem overwhelming to a new player.
