At Brailletec.de I found a Sudoku-game for both blind and seeing people with Braille on the chips and sheets.
The Sudoku board consists of an aluminum plate laminated with a magnetic foil. That way metallic parts may be fixed easily. You can put a sheet with the Sudoku task on it. The sheet will be fixed with the chip box and it is cover.
The chips are made of thin metal plates, 18 mm in square, embossed with the numbers 1 to 9. The chips can be placed on the empty fields of the Sudoku sheet. The price for this braille Sudoku game is Euro 49 / US$ 65. More information at Brailletec.de. Happy Puzzling!
