# Sudoku vs Number Join

The clearest difference is rating: Sudoku at 4.8 against Number Join's 4.2. Sudoku also leads on ads (none vs shown) and ratings volume (1.1K vs 59). Number Join's advantage is iOS requirement (13.0 vs 15.6). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Sudoku sells 11 one-off in-app purchases and Number Join 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 4.2. That said, the two scores are not equally well evidenced: Sudoku has 1.1K ratings behind it against 59, 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 89% of Number Join's.

Sudoku ships an update every 3 months, Number Join every 5 months. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
