Sven's SudokuPad

Sven's SudokuPad finally lets you play your own Sudoku puzzles in the same app as used by Cracking the Cryptic in their videos. Created by Sven, the same developer who has created and improved the Cracking the Cryptic Sudoku webapp over the past year. It also includes a few brand new classic Sudokus created by Simon and Mark exclusively for Sven's SudokuPad.
