# Sudoku vs Ripple Effect

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.

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.

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.
