# Sudoku HD! vs Sudoku

The clearest difference is ads: Sudoku at none against Sudoku HD!'s shown. Sudoku also leads on monetization model (free vs free with in-app purchases) and rating (4.8 vs 4.5). Sudoku HD!'s advantage is ratings volume (771 vs 5). On price and in-app purchases there is nothing between them.

Both are free to download. Sudoku HD! sells 10 one-off in-app purchases and Sudoku sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sudoku holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Sudoku HD! has 771 ratings behind it against 5, so its average is the more settled of the two.
