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.

Something for Everyone
Enjoy Sudoku
Use the tutorial to learn advanced techniques

With unlimited play at 16 difficulty levels, novices and experienced players alike will appreciate Enjoy Sudoku. The comprehensive tutorial (with advanced techniques including X-Wings, sashimi fish, XY-Chains, and Alternating Inference Chains), extensive feature set, and gradual hint system offer something for every player. The more you play, the more you will enjoy it.

Need a Hand?

All games are true Sudoku, with symmetry and a single solution that can be discovered by logic alone. If you doubt that a puzzle can be solved by logic, simply have the hint system explain it to you step by step.

The multistage hint system starts with a gentle reminder to get you back on track, and works up to an illustration of the exact technique to use and how it applies to the current board. The hints ease those frustrating moments and teach you how to be a better player.

Details, Details

Enjoy Sudoku doesn't skimp on additional features and preference settings. Check it out:

  • Enter your own puzzle or one from a newspaper to solve using Enjoy Sudoku
  • Select your digit style, including Kanji and Hanzi
  • Turn highlighting off or on to help you discover patterns
  • Use automatic or manual pencil marks
  • Watch the in-game clock to compare your time with those of other players
  • Save your game and try other puzzles, then return to a saved game later (even after you've finished it)
  • Choose from 6 color schemes and 3 menu backgrounds

To play for free, try Enjoy Sudoku Daily (the free version of Enjoy Sudoku).

5.0 out of 5 stars Playable and enjoyable May 13, 2011
Rare example of Android Sudoku which generates proper puzzles: symmetrical and with one solution. Difficulty levels are correctly and consistently named. Highly efficient method of entry. Very helpful highlighting system. And one feature that is surprizingly rare - automatic pencil marks generatio (if you want it). I play this one daily - other versions were either boring or annoying.

4.0 out of 5 stars Best sudoku app around May 13, 2011
Verified Purchase
Definitely grab this today if you have any interest in a sudoku app. There's plenty of them around, some that are free. But this one is by far the best i've used. I can't say that it's worth $3 for everyone, as i'm not personally a hardcore sudoku guy. But really, the tutorials really make this worth it. The hard puzzles are actually challenging. Theres no shortage of puzzles. The highlighting system rocks, as well as the best hinting system i've seen..I need a lot of hints ^_^ so I very much appreciate the attention to detail there. The main menu doesn't look like anything special, but the actual board is clean and clear. Nice job, and definitely worth the money for people who love sudoku. Enjoy!

Phone: Droid X(Android 2.2.1, Liberty 2.0.1)

I have been playing Sudoku for years on paper, computer, iPhone, and Android. This is the best Sudoku app I have ever come across. The variety of puzzles is fantastic and the selection is uncomplicated. Having played it, I would recommend it whether it were free or cost up to $5. If you love Sudoku, you'll love this app.

5.0 out of 5 stars KILLER APP on KF!!! December 19, 2011
I've tried five or six sudoku apps, with varying degrees of satisfaction. I review here Enjoy Sudoku (ES) for the KF.

Enjoy Sudoku is one of the best board-type game applications I've ever seen, across all forms of games, across several platforms.

The display is beautiful. I typically play with my KF in portrait position. I've tried landscape; it works perfectly, but it's just not to my taste. The highlighting of completed row/box is useful. Highlighting "all number N used" is extremely helpful, but having the display flash in different colors takes a bit of getting used to.

The user controls are OK:

- Entering choices using the box-first approach is intuitive. Entering number-first-then-box is claimed to be faster, but again, it takes some getting used to. (Because of the highlighting feature, I've not been able to get used to it because of the way the colors change back and forth.)

- The undo/back-track command is really great. I haven't yet found how deep the undo stack is, but I've exercised it pretty well, I think.

- I've used the rotate/mirror commands only once, but the change of viewpoint enabled me to finish a "fiendish" (toughest level) puzzle. Bravo.

- I have yet to figure out what other command buttons do - from my perspective, ES behaves just a tad strangely when some buttons are pressed. I suppose I should read the manual, but a perfect app is written so all controls are intuitive.

A truly strong point of ES is the range of available daily games: there are FOURTEEN levels, ranging from trivial to, well, really really (near impossibly) hard. Winner, winner, chicken dinner. There is a slight discontinuity in difficulty: the game takes a big jump somewhere around "moderate" or "intricate.

5.0 out of 5 stars great product January 7, 2012
Verified Purchase
great product - should be 10 stars. I love this!!! It is intuitive and easy to use.

I like how the screens are laid out, with the big numbers for entries and little numbers for entering 'pencil marks'.

They have a great product here. It is obviously well designed and tested.

I will look for more products from this company.

If you like Sudoku you have to get this!

This Android game is the best, smoothest, quickest sudoku game engine I've ever used. It is better than any I've used in a browser or as a download game on my computer.

It includes 3 tutorial lessons, and then 13 different skill levels.

It compares your times to those of many other players to show you how you're doing, statistically.

You can use "Hint" > "Check Entries" at any time without penalty --it won't respond with "Everything is just fine," until you've entered all of the essential pencil marks-- or else you can take advantage of their graduated hint system or automatic pencil marks.

You can also enter the given digits of a printed puzzle in order to solve it within this game.

You don't have to have Internet access at the time you are playing: you can play while your phone is in "airplane mode".

5.0 out of 5 stars app is great; amazon drm is fixed November 19, 2012
Verified Purchase
This app is great but the experience is ruined by the faulty amazon DRM. Ever since android 4.2 I must enter my amazon email and password every time I play. I wish I had bought this in goggle play instead. Come on amazon. Do the right thing.

UPDATE: There is a fixed version of Amazon Appstore that eliminates the constant login bug. Open appstore, click settings and the update should be triggered. Thanks amazon!
