# Sudoku vs زنجیره اعداد

The clearest difference is monetization model: زنجیره اعداد at free with in-app purchases against Sudoku's subscription. زنجیره اعداد also leads on update cadence (every 2 weeks vs every 5 weeks) and review sentiment (82% vs 69%). Sudoku's advantage is ratings volume (17K vs 1.6K). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Sudoku sells 7 in-app purchases, starting at $3.99 per month and زنجیره اعداد sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Sudoku against 4.9 for زنجیره اعداد. That said, the two scores are not equally well evidenced: Sudoku has 17K ratings behind it against 1.6K, so its average is the more settled of the two. Written reviews are what separate them: 69% of Sudoku's written reviews are positive against 82% of زنجیره اعداد's.

Sudoku ships an update every 5 weeks, زنجیره اعداد every 2 weeks. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
