Might want to make it extra clear that you’re looking strictly for land borders? Today’s country, Denmark, has a bridge that connects it to its neighbor, Sweden. But Sweden was not what Neighborle was looking for as a valid answer.

Oh, and technically Denmark also has a land border with Canada (if you’re not excluding Greenland): https://en.m.wikipedia.org/wiki/Hans_Island

It seems like Greenland is treated as a separate territory, that's why it's not red and can be selected in the dropdown. Not sure if it knows about Canada - Greenland border though... I guess we'll find out when it shows up

Yeah. Bad day for this website to show up on HN if it’s built this shoddily.

No need to be insulting

Pedantry-proof is a bit higher bar than non-shoddy

It does mention in the how to play (under the question mark) that it only looks at land borders.

Worth noting that something very similar is already a component of Worldle

Cute, but what about maritime EEZ borders?

Good point. Am curious: what’s the thick black line over land that goes all the way down to Switzerland? Does it affect the sea zones?

The drainage boundaries AFAICT. On one side of the line any rainfall flows downhill to joins a river that ends up in the North Sea, on the other side of the line it goes downhill to any other body of water.

Curious if it gets some of the edge cases right. France's longest land border is with Brazil, for instance.
