# Sudoku vs Sudoku #

The clearest difference is in-app purchases: Sudoku # at none against Sudoku's 11. Sudoku # also leads on review sentiment (79% vs 65%). Sudoku's advantage is ratings volume (59K vs 324). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Sudoku sells 11 in-app purchases, starting at $0.99 per month. Sudoku # asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Sudoku against 4.7 for Sudoku #. That said, the two scores are not equally well evidenced: Sudoku has 59K ratings behind it against 324, so its average is the more settled of the two. Written reviews are what separate them: 65% of Sudoku's written reviews are positive against 79% of Sudoku #'s.

Sudoku ships an update monthly, Sudoku # every 3 weeks. The most recent releases landed on September 27, 2026 and September 19, 2026 respectively.
