***** - "Very addictive once you master the method - A very easy game to pick up and play at any time with lots of ways to improve your score each time. Great idea!" "This is the nerdiest game I've seen for a while. Love it!" - pfg​2009 DefragGame is a fun, simple and highly addictive puzzle strategy game where goal is to arrange the colour blocks into larger same colour groups by reorganising them. Do this by dragging them into empty slots next to the same colour. The game is complete when there are no fragments left. Your score starts at 1,500 on easy, 2,000 on medium and 2,500 on hard. You lose 10 points per second taken and 2 points per move made. That score is then multiplied by your compactness ratio. Fewer gaps between the beginning and end of all the files means a better compactness ratio and a higher score.
