# Mars vs Infinity Sudoku 9x9

The clearest difference is ads: Infinity Sudoku 9x9 at none against Mars's shown. Infinity Sudoku 9x9 also leads on review sentiment (100% vs 91%). Mars's advantage is ratings volume (22K vs 2) and iOS requirement (12.0 vs 16.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Mars sells 10 one-off in-app purchases and Infinity Sudoku 9x9 sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Infinity Sudoku 9x9 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Mars has 22K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 91% of Mars's written reviews are positive against 100% of Infinity Sudoku 9x9's.

Mars ships an update monthly, Infinity Sudoku 9x9 every 3 weeks. The most recent releases landed on November 1, 2026 and October 18, 2026 respectively.
