You will be shown 10 random numbers between 1 and 100 without knowing what's next. Your task is to put them in order! But beware, if a number cannot be placed, the quiz ends...
Good quiz but i would specify that its population by city proper or municipalities. Cities like Amsterdam, Stockholm, Athens, Brussels, and Lisbon have 2+ million people but the cities are broken up into smaller municipalities. Not saying all quizzes have to be metro area but it should at least be specified.
