Smarty pins in an interactive Google maps based geography and trivia game. It allows users to play a short trivia game which requires them to answer using pins on a map. It is a relatively simple concept but incredibly fun.
The app uses a timer and hinting system which provides the user with a bonus for getting answers right or reduces your life points based on your distance from the answer.
This is a good example of a good design because it is simple and intuitive, everyone has seen a map and knows how to click a pin to select a point. It also provides knowledge without the user even being aware. This web based application can be used with children or anyone who just wants to pass some time while increasing their geographical knowledge.
