Very nice sudoku interface

There are obviously a lot of sudoku games out there. So why should you get this one? I really like the interface. It is easy to play on both my Mac laptop and on my Kindle Fire. It gives me the information I want in trying to solve the puzzle. There are wide range of difficulties of new puzzles available every day. If you want to stick with one difficulty, it will generate new random puzzles for you. But the best thing I like is the hints tutorial interface. If you ask for a hint, it might tell you to look for some technique that you have never heard of. You can then have it teach you how that method works, and go through a very nice tutorial on it. So it teaches you as you go.

Love this game!!

I have this Sudoku game version on all my devices, and I play the game daily. I really like the large level selection, so you can incrementally work toward solving more complex puzzles, and there seem to be an infinite number to solve. You can save an unfinished puzzle, and go back to it. If you are new to the Sudoku experience, there are tutorials to strategies to solve the puzzles. It is user friendly and I never seem to have any issues or glitches with updates. The app always performs well and is truly enjoyable!!

My computer randomly locks up with this app

I would give this five stars, because I really like the way this works. But I have a big problem with it locking up my computer. I tried the free version first and had that problem a lot. The paid version advertised that it was updated to work with new operating systems, but I had the same problem with this one. I really like the fact that there are new puzzles every day, so I can try multiple puzzles at different levels.
