This app is a fun way to try to beat crazy scores by sorting numbers. You have to do it as fast as possible, without making mistakes while sorting numbers. The game is easy : you have 4 numbers, and you have to click on each number with a given sort order. When you succeed in sorting 4 numbers for a series, you get 4 points. If you fail, you lose 1 point on your score. While you are playing, you can see your points per second average on a chart.
