Blindfold Sudoku is a fully accessible Sudoku game for both sighted and visually impaired people, designed for rapid audio play.
Blindfold Sudoku comes with 5 Sudoku 9-by-9 puzzles - easy, medium and difficult - and is controlled through gestures. It doesn't require voice-over but is fully compatible with voice-over.
The Sudoku puzzle board is not visible; instead, you play by listening. Tap on a cell to hear what's in the cell, swipe right to hear the row, swipe down to hear the column and swipe up to hear the square. Blindfold Sudoku gives you audio cues to tell the difference between the initial puzzle cells and the cells you fill in, and it lets you set multiple candidates for a cell.
You can customize the game to your liking: how much extra information is spoken and how quickly it is spoken.
Blindfold Sudoku was suggested at a meeting in the Boston area with several blind gamers who enjoyed Blindfold Racer and wanted to see more games in the same style - audio games that were equally accessible for visually impaired and sighted people, ensuring sighted people don't have any advantages by seeing the screen. In Blindfold Sudoku, the screen is dark.
