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
