Verdict

The call

The clearest difference is rating: ™ Sudoku 4x4 at 4.3 against 5x5!? Easy SUDOKU Eccentric Version's 1.0. ™ Sudoku 4x4 also leads on ratings volume (54 vs 1). 5x5!? Easy SUDOKU Eccentric Version's advantage is review sentiment (100% vs 67%) and update cadence (every 3 weeks vs every 35 months). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

™ Sudoku 4x4 holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: ™ Sudoku 4x4 has 54 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of 5x5!? Easy SUDOKU Eccentric Version's written reviews are positive against 67% of ™ Sudoku 4x4's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

5x5!? Easy SUDOKU Eccentric Version ships an update every 3 weeks, ™ Sudoku 4x4 every 35 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
