First choose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’ – Beginner is 200km radius, Intermediate 100km, Advanced 50km, and Expert 25km. Then, enter 10K+ population cities and all 10K+ population cities within that radius will automatically fill in.

HOWEVER, for this ‘No Repeats’ quiz you cannot name a city which has already been covered in blue – makes for a bit more of a challenge to cover the countries!

hugequiz Premium members will see the 25 largest missed cities at the end of the quiz as large, purple markers.
