# Dolls Stack vs Unsolved Case Files 3D

The clearest difference is ratings volume: Dolls Stack at 3.6K against Unsolved Case Files 3D's 13. Dolls Stack also leads on rating (4.7 vs 4.4). Unsolved Case Files 3D's advantage is review sentiment (67% vs 51%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Dolls Stack sells 17 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.

Dolls Stack holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Dolls Stack has 3.6K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 51% of Dolls Stack'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.

Dolls Stack ships an update every 8 days, Unsolved Case Files 3D every 2 weeks. The most recent releases landed on October 2, 2026 and September 18, 2026 respectively.
