From the Homepage of Kidult Game:
A "geographical" challenge with questions and answers, and a pizzico (smidgen) of strategy that always fits. Choose your flag and challenge your friends, if they accept you’ll score too, but if they refuse you will have to answer! A great chance to gain a high score, or to make a low one!
Sixty flags to find out how large the world is!
