Miracle Sudoku

You can apply the positive words of this review to any of their products. They’re all the same design, and all feature a collection of hand-made, extremely finely crafted puzzles, and they play just as well on phone as they do PC. Miracle Sudoku combines all these puzzle types in interesting new ways, with a focus on trying to include as few starting clues as possible, but I think it gets too difficult too soon.
