Flawed
A couple of flaws that prevent 5 stars. First is that the game makes it too easy for you by removing a lot of the ambiguity automatically. This is done by auto crossing out of spaces and by letting you know exactly which section of a row or column you just solved. Second the game penalizes you if you accidentally or erroneously mark the wrong square. Don’t do that, just let me keep playing until I get the puzzle correct. This game is okay for beginners but if you’re experienced and want to jump into some hard puzzles immediately then you need to look elsewhere.
