Smarty Pins is a browser-based game developed by Google that test your knowledge on geography across a number of categories: arts & culture, science, sports & games, entertainment and history & current events. You have to answer by placing a pin on a map.
You start each game with a bank of 1,000 miles/ 1,609 kilometres. You can lose miles/ kilometres for answering incorrectly and or taking too long to answer. The game subtracts the number of miles/ kilometres you're off by for each answer.. Fast, correct answers earn extra miles/ kilometres to keep the player’s journey going longer. When your bank hits zero, it is game over.
You can share your scores via Twitter, Facebook or Google+.
As simple as addictive.
