How does this work?
Clicking the “Test drive now” button launches a copy of this app on Amazon Elastic Compute Cloud (EC2), a web service that provides on-demand compute capacity in the cloud for developers. When you interact with the simulated phone using your mouse and keyboard, we send those inputs over the Internet to the app running on Amazon EC2 — just like your mobile device would send a finger tap to the app. Our servers then send the video and audio output from the app back to your computer. All this happens in real time, allowing you to explore the features of the app as if it were running on your mobile device.

5.0 out of 5 stars Excellent Sudoku App December 24, 2011
By Shari
Verified Purchase
Not only does this app work like a charm, it's also a lot of fun and boasts an excellent interface and multiple varieties and skill levels. Across all the platforms I currently own/use, this is my favorite of all the Sudoku games I've tried. It's just so simple to fill in the numbers and just works so smoothly.

5.0 out of 5 stars Way too much fun January 29, 2012
Verified Purchase
I love sudoku, and when I downloaded this one onto my Fire, I fell in love immediately. Its layout is well thought out, with a space for both the puzzle and for selecting the answers. It also has a feature (which I am sure I can turn off if I want to) of highlighting all the other similar numbers out there, which helps me see what I have to do next. I am going to delete my other Fire Sudoku now, because this one is so much better. And the price is right too.

5.0 out of 5 stars Best sudoku I've tried December 5, 2011
Verified Purchase
This has the best interface I've seen - facilitates fast entry of notes and answers. Graphics are clean and pleasing. The variety of puzzles types keeps it fresh, and there are more difficulty levels to choose from. This is my favorite out of around five different apps I've used on the ipad, kindle, and kindle fire.

5.0 out of 5 stars Sudoku 2 Free -- Set Your Own Level of Difficulty December 30, 2012
Verified Purchase
All of the positive remarks that others have written apply: it is easy to play, has a great format, etc. Its features such as highlighting numbers already inserted, indicating when an inserted number conflicts with a former entry, etc are also great assets to help one overlook entry errors. I agree that instructions are somewhat vague (almost lacking entirely), so here are some tips. Some reviewers complained that the difficulty level cannot be controlled, which is not true. TO CHANGE THE DIFFICULTY LEVEL, when you finish a game, instead of clicking on the Next Game button,tap the back arrow until you see NEW GAME listed as an option. Click on NEW GAME. Here you control what difficulty level you want the new game to be in. It's as simply as that! ANOTHER TIP: if you are curious as to how you're doing or the check if you have any errors, tap the question mark. It will tell you if you have any errors. ANOTHER TIP: to delete numbers, simply tap the X and then go about tapping on the numbers you want to delete. If you want to put in "pencil marks" click on the number and the pencil, and again go about adding numbers where you want them.

Hope some of these suggestions help to eliminate any confusion or frustration.

3.0 out of 5 stars Great app, but sleazy deceptive ads. April 4, 2013
Verified Purchase
Minus two stars because many ads on the free version are made to con the user, for example by telling them their phone is infected with a virus, or they have a new facebook message. this app is very popular now, why doesn't the author work with legitimate advertisers instead of scammers?
