Picture of a 12x12 Sudoku puzzle

On this picture you can see a 12x12 Sudoku puzzle with inner areas in a ladder pattern. Instead of numbers or letters, this Sudoku uses signs of zodiac as gaming pieces. The board graphic comes from the 'Astro12Package' that is available as download at the MaaTec Boards page. Of course you can use a standard board or other graphics with numbers or letters in the Sudoku program.
