I have just seen this article about a Wikipedia game: https://www.howtogeek.com/840449/have-you-played-the-wikipedia-game/
It would be interesting to have a similar thing for our OSM wiki, where users can learn a lot about the map.
What do you think?
https://wiki.openstreetmap.org/wiki/Special:Random is also available in our wiki, like in every wiki. I’m not quite sure if this is what you were looking for? I believe it’s very hard to play a similar game in our wiki, as lots of pages have very few inbound links.
