***** - "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.

Verdict

The call

The clearest difference is price: Defrag Game at Free against neoDefense's $1.99. Defrag Game also leads on in-app purchases (none vs 5) and rating (5.0 vs 4.7). neoDefense's advantage is ratings volume (548 vs 1) and update cadence (every 2 months vs every 4 months). On review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Defrag Game holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: neoDefense has 548 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Defrag Game's written reviews are positive against 88% of neoDefense's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Defrag Game ships an update every 4 months, neoDefense every 2 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
