There's a similar game, but for guessing both the year and the location

https://timeguessr.com/

Discussed on HN a couple of years ago too: https://news.ycombinator.com/item?id=37203511

edit: found another game like OP in the linked thread https://www.chronophoto.app/game.html

Another for year + location https://whentaken.com/

Holy, I was off by 7 years and 427km on my first guess and I don't want to play anymore because I've surely peaked

The whole collection is great:

Where do these sites source the photos from?

This is a nice idea. Only issue are the ads - the ad on the bottom right is bleeding over the photo, there are two video ads playing simultaneously... Makes it annoying to play

I had to close it - the ads are all over the place.

https://pointguessr.com is another one, it's like timeguessr but with real-time co-op functionality
