Verdict

The call

The clearest difference is review sentiment: Choco abacus at 88% against Microsoft Sudoku's 37%. Choco abacus also leads on in-app purchases (none vs 2) and iOS requirement (9.0 vs 12.0). Microsoft Sudoku's advantage is rating (4.7 vs 3.2) and ratings volume (7.4K vs 5). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Microsoft Sudoku holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Microsoft Sudoku has 7.4K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 88% of Choco abacus's written reviews are positive against 37% of Microsoft Sudoku's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Choco abacus ships an update monthly, Microsoft Sudoku every 2 months. The most recent releases landed on September 21, 2026 and September 30, 2026 respectively.
