# Hidden Objects vs Unsolved Case Files 3D

The clearest difference is ratings volume: Hidden Objects at 13K against Unsolved Case Files 3D's 13. Hidden Objects also leads on rating (4.7 vs 4.4). Unsolved Case Files 3D's advantage is update cadence (every 2 weeks vs every 3 weeks) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Hidden Objects sells 3 one-off in-app purchases and Unsolved Case Files 3D sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Hidden Objects holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Hidden Objects has 13K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 60% of Hidden Objects's written reviews are positive against 67% of Unsolved Case Files 3D's, so the app with the better star average is not the one people write more warmly about.

Hidden Objects ships an update every 3 weeks, Unsolved Case Files 3D every 2 weeks. The most recent releases landed on September 23, 2026 and August 11, 2026 respectively.
