# Sudoku HD! vs :-) Sudoku

The clearest difference is in-app purchases: :-) Sudoku at none against Sudoku HD!'s 10. :-) Sudoku also leads on ads (none vs shown) and device support (3 vs 1). Sudoku HD!'s advantage is rating (4.5 vs 4.0) and ratings volume (771 vs 29). On price there is nothing between them.

Both are free to download. Sudoku HD! sells 10 one-off in-app purchases. :-) Sudoku asks for nothing beyond the download.

Sudoku HD! holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Sudoku HD! has 771 ratings behind it against 29, so its average is the more settled of the two. Written reviews point the same way: 87% of Sudoku HD!'s written reviews are positive against 77% of :-) Sudoku's.
