First choose a number of cities to begin – ‘100’, ‘250’ or ‘500’. You begin with 30 seconds for 100, 1 minute for 250, and 3 minutes for 500. Name as many of the largest World cities you can (based on how many you chose), gaining 1 second on the clock for each city you name. Object is to name as many cities as you can before time runs out. There are no time bonuses except the 1 second per city.
