The extreme difficulty doesn't seem very difficult. I am no master sudoku player but I always complete the extreme puzzles in a relatively short time. It needs to be more difficult. Otherwise very well put together Game
One of my favorites but it loses two stars because it simply does not generate the proper diffeculty puzzles. Never know what you are going to get. Fix that and I'll give it 5 stars.
Sometimes I accidentally hit the wrong button and is that the controls fault or my fat figures? Idk. Wish I could give it 6 or 7 stars. Love this game
The only thing I wish I was able to do is to use my stylus to write in the digits. Other than that, it is truly a great app. Lots of custom options and simple interface. Love it.
This game should come with a Surgeon General's warning for addiction. I can't sleep at night until I've done a few Extreme puzzles in under 10 minutes. Always racing to beat my best time keeps me addicted.
Pretty easy ui to work with. Not all that flashy, but I don't want it to be. A solid soduku version. Thank you for the free app sale.
Gives you control, knowledge and ability to use a strategy. And when you get stuck you can validate the puzzle to find errors.
Superb implementation of a classic game. Very intuitive UI and quite customisable as well. Resumes from partially solved puzzle perfectly without any hitches! Totally worth it! Cheers!
Works well, no ads, not overly flashy, and enough options to tune to your liking. :) keep it up!
Love the game, but the improved graphics look blurry on my RCA Voyager tablet (1024x600 screen).
Everything you need to play the game. Well laid out and this is indeed my goto game. No fancy graphics just good Sodoku fun.
It helps me relax. Sudoku is boring at times.. but good for the mind. 5/5
I want to know why there is so difference in difficulty in games of the same rating.
Big improvement on contrast and controls. These were the only issues I had with the old version. Great update!
The options to highlight and crosshair are all greyed out and will not work, much worse than the free version
Amazing app been using for a long time. Buying is just the next right thing to do, they deserve it. Excellent support too.
It chooses levels for you. I want to do a hard, it comes up a hard+ which is close to extreme, but other than that it's by far the best sudoku app out there
Gives you what you expect in a soduku game and it highlights numbers so its easy to assume the location of tje numbers. I bought after playing the free version for 2 years. Worth every penny
Great app. Was installed on previous phone, and was the first app I installed on new phone.
Controls are intuitive; interface is simple. Great app to get a fix of Sudoku.
I am addicted. Very fun and easy to use.
I think that this is a good sudoku. I played little but everything looks OK in it.
Amazing app.. I spend most of the time trying to break my records..
This so a great sudoku app. I have played other apps but I keep going back to this one. Its just all-around great!!
Very good it improves our thinking power our brain becomes sharp. Try to create more and more puzzles
Very enjoyable.. Love it.. Seems to cater fir all levels
The best sudoku app I have found
Could have more stats like average time to solve, but it works which is more than you can say about other Sudoku apps.
Auto pencil marks won't work
Fantastic! Well controlled, set out etc, plus it's incredibly addictive. I'll never become bored with this! Thank you, genina!
I've been playing this app for literally years, i love it. It's so functional and good fun to play. Excellent!
Could use some harder puzzles, and perhaps an advanced techniques guide for those wanting to master the game. Great app otherwise.
best sudoku app... try it and you just know
Well done game. I was so impressed with it that I bought the premium version.
Very nice sudoku puzzle. Large easy to read numbers (even the small ones). Pleasing color scheme. Quick and easy entry.
Simple. Highlights intersecting numbers for you. Challenging levels. Love it.
Very good! Best Sudoku out there!
This is a great game. It makes you think fast.
Nothing fancy but exactly what you need.
Contrast fixed in free version, so I decided to upgrade. Much better layout on premium version
