# Number Puzzle vs Stacky Water 3D

The clearest difference is review sentiment: Number Puzzle at 100% against Stacky Water 3D's 0%. Stacky Water 3D's advantage is rating (4.5 vs 3.8) and in-app purchases (none vs 1). On price and device support there is nothing between them.

Both are free to download. Number Puzzle sells 1 one-off in-app purchase. Stacky Water 3D asks for nothing beyond the download.

Stacky Water 3D holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Stacky Water 3D has 147 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 100% of Number Puzzle's written reviews are positive against 0% of Stacky Water 3D's, so the app with the better star average is not the one people write more warmly about.
