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'.
