Two families of questions share this quiz: the capitals, asked in both directions, and the flags of the countries of Europe, to be recognized among several pictures. In all, there are 90 questions, 42 about capitals and 48 about flags, drawn in a balanced mix in every game. The warm-up asks 30 questions in three minutes, then comes a sprint of only 20 seconds, which demands answers at the speed of reflex. It is this nervous rhythm that makes the quiz so addictive. A good training to revise Europe before a test, to prepare a trip or simply to have fun with friends.
