# Sudoku.com vs One Brain

The clearest difference is review sentiment: One Brain at 59% against Sudoku.com's 31%. One Brain also leads on update cadence (weekly vs every 3 weeks). Sudoku.com's advantage is ratings volume (1.9M vs 297) and rating (4.8 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sudoku.com sells 1 one-off in-app purchase and One Brain sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sudoku.com holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Sudoku.com has 1.9M ratings behind it against 297, so its average is the more settled of the two. Written reviews complicate that: 31% of Sudoku.com's written reviews are positive against 59% of One Brain's, so the app with the better star average is not the one people write more warmly about.

Sudoku.com ships an update every 3 weeks, One Brain weekly. The most recent releases landed on November 9, 2026 and November 6, 2026 respectively.
