This zefrank.com memory games site asks “How well do you know your world?” and then puts you to the test — But think fast! It’s a race against time and miles, and the map is tiny! Try to get your pin as close as you can to the country, city, or famous place the game throws out at you, and climb through the 12 levels from easy to difficult. But watch out, you might find yourself playing this game over and over again. The consolation is that you will learn something as you play.
