I really wanted to like this one. Clean, simple, complete interface with no extraneous eye-candy clutter. Just Sudoku. Except that its not Sudoku.
While I am far from an expert Sudoku player, I do know that true Sudoku puzzles are symetrical. These are not. End of story. In fairness, the same is true of many of the Sudoku apps in the App Store.
