# Sudoku vs Sudoku + Auto

The clearest difference is ads: Sudoku at none against Sudoku + Auto's shown. Sudoku also leads on ratings volume (1.1K vs 63) and review sentiment (95% vs 85%). Sudoku + Auto's advantage is update cadence (every 5 weeks vs every 3 months) and iOS requirement (13.0 vs 15.6). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sudoku sells 11 one-off in-app purchases and Sudoku + Auto sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sudoku holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Sudoku has 1.1K ratings behind it against 63, so its average is the more settled of the two. Written reviews point the same way: 95% of Sudoku's written reviews are positive against 85% of Sudoku + Auto's.

Sudoku ships an update every 3 months, Sudoku + Auto every 5 weeks. Both last shipped on October 24, 2026.
