I launched https://thecitymapquiz.com some time ago and I really don't have any succeed critia for it. It was fun to built, playing around with rendering open street map data, and building the web part with phoenix liveview. I really don't have any plans to it going forward, and with a couple of small kids and a full-time job, I'll probably not have any time to spent on it if I actually had a plan. So in someway you could say it's already a success whether or not anyone will use it.

I think I saw this in a different HN comment of yours and played it. Love the concept. My only suggestion is that you expand the multiple choice option pool. I could rule out a lot of options later on in the quiz simply by remembering what options had already been used.

Could you add two multi-player options?

1) participants guess in turns, every correct choice gets a point

2) participants guess competitively and first right choice gets a point. Wrong choices are shown to others, result in a point deduction, and the game continues until the right choice is made
