# K.O. Sudoku vs Math Dims II

The clearest difference is rating: Math Dims II at 5.0 against K.O. Sudoku's 4.4. K.O. Sudoku's advantage is update cadence (every 4 days vs every 10 days) and ratings volume (8 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. K.O. Sudoku sells 3 one-off in-app purchases and Math Dims II sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Math Dims II holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: K.O. Sudoku has 8 ratings behind it against 1, so its average is the more settled of the two.

K.O. Sudoku ships an update every 4 days, Math Dims II every 10 days. The most recent releases landed on November 3, 2026 and October 5, 2026 respectively.
