# UeharaPuzzle vs Sand Block

The clearest difference is review sentiment: UeharaPuzzle at 70% against Sand Block's 27%. UeharaPuzzle also leads on in-app purchases (none vs 1). Sand Block's advantage is update cadence (daily vs every 4 months) and ratings volume (36 vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sand Block sells 1 one-off in-app purchase. UeharaPuzzle asks for nothing beyond the download.

Sand Block holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Sand Block has 36 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 70% of UeharaPuzzle's written reviews are positive against 27% of Sand Block's, so the app with the better star average is not the one people write more warmly about.

UeharaPuzzle ships an update every 4 months, Sand Block daily. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
