A random World Capital has been put in the centre! Below it you are shown, in order, the 4 capital cities that are closest to it when going South (rhombus bearing between 157.5º and 202.5º). To its right, you have the 4 closest capitals cities that are in the East direction; going down and right you have the 4 closest in Southeast direction and so on.
To make sure you really mean to guess the target capital you have to TYPE ITS NAME TWICE! eg if the quiz was about US Capitals and the answer was Boise you'd have to type Boiseboise
If you see that one of the cells that could hold an answer doesn't have a border, it means that there aren't enough capitals in that direction so that cell holds no answer
Google Earth seems to indicate that the bearing from Vaduz to Stockholm is 19.3 degrees. Why isn't Stockholm included in the North direction of the target?
According to the list of capital city coordinates Vaduz is 47.14151 9.52154 and Stockholm is 59.33258 18.0649. This gives, using the bearing formula I have on Excel, a 'rhombus bearing' of 22.57 which is just enough to fall into the Northeast section. 'Rhombus bearing' means that you can reach Stockholm by following constantly this bearing, however this doesn't make you take the shortest path .I didn't know about the Google Earth bearing function, I will give it a go later to try and understand which one is more correct, thanks!
so I have seen that google earth gives 19º Vaduz-Stockholm but 206º going Stockholm-Vaduz, which is 'South-West'. So I think Google Earth gives you the initial bearing of the shortest path and I think it's best to use the 'rhombus' bearing. For example this always gives 90º when going from one point on the Tropics to another, unlike Google Earth
