I am addicted to this! A lot of my free time is being spent trying to improve my last score.
To play click on: “run the test” bottom left hand corner and then check which areas of the world you want to test your knowledge in.
I have most countries down - except in Africa - still working on getting 100% on those. Then, I’m going to work on capital cities, bays and gulfs, islands, seas and the rest. Fun fun!
