Verdict

The call

The clearest difference is price: MultiSudoku at Free against 3Doku's $2.99. MultiSudoku also leads on review sentiment (93% vs 67%) and ratings volume (2.4K vs 1). 3Doku's advantage is in-app purchases (none vs 10) and iOS requirement (12.0 vs 15.6). On rating and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

3Doku holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MultiSudoku has 2.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of 3Doku's written reviews are positive against 93% of MultiSudoku's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

3Doku ships an update every 10 months, MultiSudoku every 3 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
