One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out. Game modes: • Colors: Does the word match the color it's written in? • Arrows: Is the arrow actually pointing the way it says it is? • Numbers: Is the math equation true or false? • Words: Which word matches the definition? How high can you score under pressure?

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
