# KenKen Classic vs Number Join

The clearest difference is rating: KenKen Classic at 4.6 against Number Join's 4.2. KenKen Classic also leads on ratings volume (3.2K vs 59). Number Join's advantage is review sentiment (89% vs 73%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

KenKen Classic holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: KenKen Classic has 3.2K ratings behind it against 59, so its average is the more settled of the two. Written reviews complicate that: 73% of KenKen Classic's written reviews are positive against 89% of Number Join'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, Number Join every 5 months. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
