Roll Doku: sudoku type puzzle app for iphone, ipad, ipod touch. Review








Download the Free version of Roll Doku & just try to do 1 puzzle. A solved Sudoku puzzle is wrapped around a cylinder. Then it is scrambled in a clever way: The rolls are shifted around horizontally. Furthermore, the rows are shifted up and down. Very tough! Yet each puzzle has 1200 solutions.

David Whitehead is the author and he boasts that Rollduko is 'the best sudoku app ever!' That's similar to many claims of 'the hardest puzzle in the world'.

    The Rolldoku puzzles look intensely hard when you first start, but like Sudoku puzzles, you logically work your way through. In my experience, they take about the same amount of time as traditional Sudoku. Some more, some less.

    I created a VIDEO with tips for solving the puzzles. Check it out on YouTube:
