The Hans Island dispute has been solved. Canada should be removed, and Denmark too possibly. When this quiz is next updated, this should be changed or a caveat added. I have not done enough research to be able to say whether or not the change has taken place yet or not.

If we are getting technical, I believe we should add Moldova. Moldova borders both Ukraine and Romania. However, the border with Romania follows a river over its full length. Therefore, Moldova and Romania only border through bridges, which is excluded by the quiz description.

Maybe we should change ‘border by bridges’ in the description into ‘border by sea bridges’?

Actually, if we are even more technical, there is one point were you can cross the border without crossing the Prut near the town of Zagarancea. The border follows a meander not connected to the river anymore and is therefore on land.

Great quiz! I only have a few complaints, Canada borders Denmark Through an island called Hans Island in Greenland, also, the United Kingdom borders more than one country. It borders Spain and Because of Gibraltar, and it also borders Cyprus because of its exclaves in the island. Other than those two things, this is an excellent quiz!

Dose Cyprus count? it borders a UK overseas territory. The quiz specifically says "not counting borders from over seas territories-such as HANS ISLAND," but that's saying the countries overseas borders don't count as actual borders. it says nothing about a country bordering an overseas territory

Guys, I've just made a brand new discovery! It's this little island located between Canada and Greenland called "Hans Island". According to some obscure, ancient documents from 2022 I've unearthed, Canada and Greenland actually share a border with each other along this island! I can't believe I'm the first person to discover this!!

Anyways I don't think this border should be added to the quiz. I did some more digging and apparently Greenland is an overseas territory of this weird European country called "Denmark", and looking closely at the description of the quiz reveals that overseas territories aren't considered for this quiz. Probably best to not include the Hans Island border, especially since it's so obscure and I'm the only person who knows about it.

I was digging through some British government archives and found an obscure document referencing a territory called "Gibraltar," which apparently borders Spain. Therefore the United Kingdom needs to be taken off the list.

I doubt anyone else has heard of it, so I'm rushing to write this without reading the caveats or any prior comments. Ain't I right?

I wonder how many of those banging on about Han Island can find it on the map.

Why get so vocal about a rock? Why not simply accept that it doesn't count here? There must be more important things to get het up about. How about my ending the previous sentence with 2 prepositions?

Even as the bombs are raining down on our heads, there will be people bleating 'But what about Gibraltar?'.
