The numbers are easy to read, and the buttons are incredibly user-friendly. Since the level of difficulty ranges from Average to Difficult, everyone from beginners to seasoned players will love this one. It can generate a virtually infinite number of games, so you’ll never, EVER get bored. But sometimes you might get stuck....when that happens, you can press the Show Hints button to get some clues. And whenever you solve a puzzle, the Facebook Upload button appears. Impress your friends with all your wins!
