Solved my first write in puzzle. I see sudoku puzzles in magazines news papers every where Take a picture of the puzzle. Copy into the app. Solve when I have time. Very good.

The absolutely best Sudoku app. It is so easy to go back and forth between trial and final numbers. One negative; I lost 2,670,000 points suddenly and don't know why. Bummer. Still great fun.

I really like this app! I can play the newspaper puzzles with the convenience of the electronic game! And the hints are a great way to learn how to play better. I can't think of anything that would improve on this game!

Very good Sudoku set, from Beginner through the Master levels. You'll enjoy the challenge and learning the various strategies it takes to win the games. Try it, I'm sure you'll like it!

Aside from the annoying nags to enter a review and the awkwardness of the interface in several areas, this is an adequate Sudoku app.

Really great puzzles! The "Very Hard" category is perfect. The Master category is beyond challenging!

Good game. Master level definitely more challenging than five-star in newspaper. Like the set up. So much easier than doing them on paper. Would love to know what scores correspond to rankings. For example, been on expert level for some time. Want to know at what score I will need to attain master. Have had one problem periodically, though. Upon completing an in-built, computer-generated puzzle, the clock keeps running. When I ask for the solution, I get a message telling me that I solved it, but only in-built Sudokus count toward my ranking. This is especially frustrating after having completed a master-level puzzle and knowing it does not get me a better ranking. Found the reason for the problem. The solution to the puzzle is not unique as it says in the directions. If you have an alternative solution, it doesn't recognize it. Very frustrating as this has happened many times. That's why I only gave it 3 stars. WOULD LOVE TO SEND A SCREENSHOT AS REQUESTED BUT YOUR MESSAGE BOARD DOESN'T ALLOW THAT. HOW CAN I SEND IT TO YOU?

The ad header can refuse to go away. In those times I can't use the input grid without constantly moving it to avoid blocking the puzzle. I thought this was permanent but it eventually went away. It took several sessions of ad watching. There has to be a balance in these things. Besides the ad issues this is the best honest way to play the puzzle. Other apps have distracting cheater features.

I love sudoku so much, I downloaded 74 different sudoku apps to see which one I liked best, and this one is on the top of my list so far.
