My average brain power cannot compute - How can Saudi Arabia & UAE be on the list, along with UAE & Oman... But not Saudi Arabia & Oman?
+14
Level 94
Jun 12, 2018
since its gdp per capita, uae+saudi & uae+oman are both greater than saudi+oman

A+B & A+C are greater than B+C... quite logic, isnt it?

Oman ranks at 32, Saudi Arabia at 14 and UAE at 8.

UAE + SA = 22 (11 avg)

UAE + O = 40 (20 avg)

SA + O = 46 (23 avg)

So because UAE > SA, then the third combination doesn't quite make the cut.

I think you meant UAE < SA

Well I meant UAE had a greater GDP per capita, rather than the actual rank. But yes, in rank terms, UAE < SA as 8 < 14.

A few countries that are close, but do not share a border:

Singapore-Brunei: 5.5;

Singapore-Malaysia: 26 (Brunei and Malaysia do border each other and score 26.5);

Australia-New Zealand: 26.5;

Japan-South Korea: 32.

You can see why Singapore (5) and Brunei (6) didn't want to be part of Malaysia (47).

+15
Level 66
Sep 14, 2018
Actually, Singapore did not secede from Malaysia; Malaysia expelled Singapore. Due in part to the anti-Chinese sentiments that led to anti-Chinese riots in Kuala Lumpur several years later.

Ireland’s recent tax haven boom has been quite recent. It used to be much poorer than the UK and isn’t nearly as ubiquitous/famous. Combine that with a population 1/10 of its more famous neighbour and it’s less guessed

How did I not get USA-Canada?!! *facepalm*

Also are we Including the French Guiana border, or is that just not very rich countries per capita. Also assuming you don't include the dubious Qatar-UAE border. Kuwait Kind of surprised me and so did not seeing Sweden-Finland, guess that is for the same reason there is no Saudi Arabia-Oman, because Norway is like UAE, it is the largest out of those three

Level 68
Aug 31, 2022
Nope, their border is between Greenland and Canada, not Denmark itself. Since this is an overseas territory (not a constituent region) then the border is not counted. (As is standard for most JetPunk quizzes)
+1
Level 48
Jul 18, 2024
Nope, this is not stated in the rules of this quiz. Some vague "side-wide standard" (which does not even exist btw) should not be applied. Canada borders Denmark. Period.
+3
Level 68
Jul 18, 2024
Well, a "site wide standard" absolutely does exist, and has been used on Featured quizzes (especially English) for many years. We can't just be adding random additions and extra rules to every single quiz, as that would mean every quiz requires paragraphs of clarifications before you can even take it => what's the point?

We're here on JetPunk to have fun, not to read essays of technicalities

Canada doesn't border Denmark. It's an uninhabited rock that isn't administered by either country. It's just about fishing rights and ocean resources. They agreed to split it just to be nice, but there is no logical reason to say that this counts as a border any more than Canada's border with France at Vimy Ridge. Heck, you might as well count embassies as borders if you count this uninhabited rock.
