# 数字九宫格 vs Sudoku

The clearest difference is rating: Sudoku at 4.4 against 数字九宫格's 1.0. Sudoku also leads on ratings volume (39 vs 1). 数字九宫格's advantage is in-app purchases (none vs 1) and iOS requirement (8.1 vs 12.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Sudoku sells 1 one-off in-app purchase. 数字九宫格 asks for nothing beyond the download.

Sudoku holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Sudoku has 39 ratings behind it against 1, so its average is the more settled of the two.

数字九宫格 ships an update weekly, Sudoku fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
