I've tried several sudoku apps and some are better than others but this one is by far the best. The difficulties range from short and simple to really challenging, and the hints feature is particularly helpful when attempting those really hard puzzles. It will compute candidates and even teach you what steps you need to do next. It really is the best!
I love this game and the many variations and playing levels offered. It is so very user friendly and intuitive. I removed all other like games from my tablet as this is so much better than any other I had found. The only problem I have with it is playing instead of working.
It WORKS! Unlike so many others that lag or don't have sensible input options. The hints and tutorials are really good too. I wish I had found this sudoku app first.
Is there a way to turn the timer off completely? I play Sudoku to relax and seeing my average time along with the amount of time that it took me to complete a puzzle does not help as I can't help myself from giving myself anxiety haha. Also if my finger slips and I put a number in the incorrect spot, it just shows the incorrect number with a circle and it gets in the way.
Andoku is the best of the sudoku apps. Lots of puzzles and customizable controls. I have been playing Andoku Sudoku for years. The only thing I don't like about the new version is the ads are more intrusive. Still 5 stars.
This sudoku app has all you need; varying levels of difficulty, tutorials, hints to show you where to look for the next one. The ads are non-intrusive.
I've had any number of Soduko apps over the past decade or so, and considered myself an advanced player. But the top 3 levels of this one are real bubble-bursters. It's shaken me out of stagnation, hopefully raising my own level. Maybe one day I'll be able to solve these without asking for a hint. Also love the custom game feature...
My previous sudoku app had a checkpoint facility to allow you to try out a solution starting with a two way guess. This one takes a different route. You make a choice and check to see if correct. Much easier. I like the colours and sounds especially when I finish a puzzle. I like this one best of all the many apps I tried.
Lots of game options and varying degrees of difficulty will allow anyone to be challenged. Never had an issue and use it often.
Interrupts game completely every time your fingers hit the space beside the one you aimed for
Great App Great Features
I have downloaded many sudoku apps and non of them is as good as this one. It even has very detailed tutorials.
I like the tutorials, hints and enter your own puzzle. The time sorted completed puzzles list makes it easy to locate your worst times and see if you can improve.
Keeps your brain active. Various levels of difficulty too.
Takes a bit of getting used to being used to other makes where you tap on a square then input number but other than that it is good quite difficult even in moderate level.
The best sudoku game, lots of options. Have to get use to the pad (select numbers first) but when u get used to it...it's just perfect!
Instead of using tutorials, use the Hint menu item to see how different techniques can be used to solve your puzzle -- not a canned example, but your actual puzzle. This is a great way to learn techniques. The ads are a distraction, and it would be great to have a way to do a "what if" path of numbers. Overall still awesome.
Clear and easy to use on phone Love the difficult ones If you are really stuck you can get clues and errors can be highlighted
This is the best free sudoku app I've found. Good alternatives, lots of different levels and difficulties!
Great selection of game types and difficulty levels. Love the ability to create custom puzzles with the camera add-on.
There are so many games for mobile. But to do some brain work in leisure this is the best choice
The hints taught me a few "techniques" that I didn't know before
App works perfect and has good feel. The only improvement I can think of would be more choices for grid colors, something other than only black or white might be easier on the eyes.
The levels are great. Ill play on tricky for a while and then ill do an easy at 1:22. The highlighted boxes help immensely to see your patterens. Best app by far.
If you love sudoku of lots of varieties and difficulties then you'll enjoy this app. Very easy to spend many hours on this app
The app is tilting even when my phone is in portrait mode. So it's useless when I want play in bed.
Best game I've come across. I've been through them all. Sticking with this one.
I love this, when you ask for a hint it helps you understand, not just give you a number! Helped you learn to play better
I am giving 5 stars for the best sudoku on Android. I would like to support the developer, but can't find any in app purchases. Where/what are they?
Of all game apps I've used so far, this the one that unceasingly keeps me coming back. It's great!
Different key strokes than im used to but the really hard ones are actually hard unlike the ones for idiots in usa today
I particularly like the way you can get hints which allow you to learn new techniques.
Especially like the options to turn assistance on and off and have it explain the next step to solving your current puzzle.
Fun game and allows mind to focus and distract from other stuff.
I've had it for a few months now & it never messes up, kepps all my unfinished puzzles and it has a crap-ton of puzzles...lol
Easiest to navigate and use. I like the various features that are offered. It's the best sudoku app I've tried and I've tried a few different ones. Uninstalled them right away.
For untidy writers like me this is brilliant!
The tutorials for tricky and harder levels are a great help :-)
Am enjoying this app. Haven't found what you have to pay for. So far, all free.
Starting to play Sudoku again. Appreciate the gradual increase in difficulty.
