Two types of questions alternate at random: sometimes a country is named and you pick its capital among five options, sometimes the capital is given and you pick the country. The quiz covers 189 countries, sorted into four difficulty levels, from capitals everyone knows to ones that make even experts hesitate. The game starts with a warm-up of 30 questions in three minutes, and the questions get harder as it goes. Then comes the sprint: one minute to answer as many questions as possible. Speed and knowledge count equally, because every second of hesitation costs you. A classic for school, for general knowledge and for anyone who wants to feel at ease in conversations about the world.
