# Ultimate_Sudoku vs Flex Sudoku

The clearest difference is review sentiment: Flex Sudoku at 50% against Ultimate_Sudoku's 0%. Flex Sudoku also leads on ratings volume (8 vs 2) and device support (3 vs 1). Ultimate_Sudoku's advantage is rating (5.0 vs 3.1) and iOS requirement (7.1 vs 15.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Ultimate_Sudoku holds the better App Store score, 5.0 against 3.1. Both are backed by a comparable volume of ratings — 2 and 8 respectively. Written reviews complicate that: 0% of Ultimate_Sudoku's written reviews are positive against 50% of Flex Sudoku's, so the app with the better star average is not the one people write more warmly about.
