About

SudokuBlind is a number puzzle app that is easy to use and fully accessible with VoiceOver. Not only blind and visually impaired players, but also sighted users will enjoy SudokuBlind. There are 4 difficulty levels: Smart, Expert, Genius and Brainteaser, making SudokuBlind challenging for both beginners and experts. In addition to the classic number puzzle, this app also offers the popular binary number puzzle. A wide range of settings allows you to customize the app from easy playing to highly challenging. You can choose to show only possible digits for each cell or enable candidate numbers. Sighted players who enjoy a real challenge can turn the screen completely black, so the puzzle must be solved by sound using VoiceOver. This is also a fair option when playing against someone with a visual impairment. SudokuBlind offers an unlimited number of puzzles. Feel free to try SudokuBlind for free. SudokuBlind integrates Game Center so you can compare scores, track achievements, and play live matches with 2 to 4 players. Tip: To navigate efficiently through the puzzle grid using VoiceOver, enable "Vertical Navigation" in the rotor settings. Swipe left and right to move horizontally; swipe up and down to move vertically.
