In the bottom left hand corner, there is a score counter and a mode button. You can either be in game mode (it tests you) or learning mode where you hover over a country and it will tell you its name. Basically, in game mode, click on the country, it tells you to. I hope you enjoy
if the screen goes blue during your game, it isn't a glitch, it is just the end of your game and you can play again by clicking new game. I hope you like it.
