# Cognizer vs 5x5!? Easy SUDOKU Eccentric Version

The clearest difference is rating: Cognizer at 4.4 against 5x5!? Easy SUDOKU Eccentric Version's 1.0. Cognizer also leads on ratings volume (5 vs 1). 5x5!? Easy SUDOKU Eccentric Version's advantage is update cadence (every 3 weeks vs every 6 months) and review sentiment (100% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cognizer sells 6 one-off in-app purchases and 5x5!? Easy SUDOKU Eccentric Version sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cognizer holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Cognizer has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Cognizer's written reviews are positive against 100% of 5x5!? Easy SUDOKU Eccentric Version's, so the app with the better star average is not the one people write more warmly about.

Cognizer ships an update every 6 months, 5x5!? Easy SUDOKU Eccentric Version every 3 weeks. Both last shipped on November 2, 2026.
