# KenKen Classic vs Calcudoku Puzzle

The clearest difference is ads: Calcudoku Puzzle at none against KenKen Classic's shown. Calcudoku Puzzle also leads on update cadence (weekly vs every 4 months) and rating (4.8 vs 4.6). KenKen Classic's advantage is review sentiment (73% vs 40%) and ratings volume (3.2K vs 51). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. KenKen Classic sells 6 in-app purchases, starting at $19.99 per year and Calcudoku Puzzle sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calcudoku Puzzle holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: KenKen Classic has 3.2K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 73% of KenKen Classic's written reviews are positive against 40% of Calcudoku Puzzle's, so the app with the better star average is not the one people write more warmly about.

KenKen Classic ships an update every 4 months, Calcudoku Puzzle weekly. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
