Verdict

The call

The clearest difference is rating: Sudoku at 4.8 against Ripple Effect's 4.0. Sudoku also leads on ads (none vs shown) and ratings volume (1.1K vs 4). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sudoku sells 10 one-off in-app purchases and Ripple Effect sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Sudoku holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Sudoku has 1.1K ratings behind it against 4, 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 80% of Ripple Effect's.

UpkeepUpdate frequency

Sudoku ships an update every 3 months, Ripple Effect every 5 months. The most recent releases landed on November 10, 2026 and November 1, 2026 respectively.
