Sudoku Widget for Homescreen for Android
Every single puzzle is 9 blocks of these 3 verticle number combinations. Take any 3x3 block in the puzzle and look at the 3 vertical rows. One column is some combination of 4-7-1, another 8-5-2, and another 9-6-3. Do that in each 3x3 block and you've solved the puzzle. You can even see it in the snapshots, if you look.

I, too, noticed the pattern in every single puzzle. At first I thought I was some genius & found a new trick to solving sudokus, but it gets old quick. However, the rest of it is implemented perfectly—it's sudoku right on your home screen! And the controls are pretty good, too/easy to manage.
