OpenSudoku

Why oh why oh why can't I find a Sudoku that will allow me to highlight rows and columns? My very very old palm pilot had a game that did just that. Really helped me learn to play, and it's faster to see patterns, double check yourself. So hard to find now. Few games

This is the original and the best. Lightweight . Completely free with no ads. Download additionally games from the link provided. I prefer UC Browser for downloading. Open the downloaded files and open it by tapping Opnsudoku from the pop up list. I winder why the publisher is not updating this awesome app. Please update.

Great interface, BUT... the best features were in the menu which disappeared when I upgraded my phone. Hints on/off, undo, bookmark points, and other configurations were in the menu. Hopefully a fix will come soon. Until then, this app isn't very good.

With new Note 5 the Recent Key no longer works in puzzle as a Menu Button. Menu function was a Very important part of this app. Can you PLEASE fix that? Otherwise, 5 stars. Excellent application. Super smooth GUI. Thanks-where can I get more puzzles? Update. Can't believe I have been playing for years. It's still the best for ease of use and reliability.

Has issues on newer versions of android. Screen flicker on S5 neo running Android 6. Was fine on android 5.1. Need to find a modern alternative.

Menus don't display properly on my Galaxy S7, Android 6.0.1, making it impossible to reset games, etc.

Been using it for years but just changed phones and is no longer compatible. Needs to upgrade for latest Android versions.

I love that you can choose your favorite way of entering digits and hints ( I use Num Pad), clear, simple intetface, no ads, loads of puzzles available. Wish list: save save points when I leave and come back, multiple save points, color cells marked with requested combinations of numbers. To those who can't find controls on newer devices, you simply hold the lower-left button rather than tap it.

I've been playing this Sudoku game for a couple of years now. It deserves 5 stars BUT I just updated to Galaxy Note 4 and the controls for the game are not available. The option to use the lower left hand device button has been changed. It only displays active applications. Please come up with a work around. I definitely want to keep playing this version. Best of all the others.

I was looking for an app where you can input sudokus from a newspaper. This is perfect and a small app, it uses hardly any memory space! To add a sudoku yourself its pretty self explanatory but for those who maybe can't figure it out, on the bottom task bar on your device press the menu button or the three dots after you open up the game. Add Folder, I put Newspaper as this folder name. Go in that and hit the menu button again to Add Sudoku. Very cool app!

Definitely the best sudoku app on the market. Simple and non off those weird colors and hint features. I wish there is a check button that tells you what number position is incorrect (which by pressing adds more time solved) but seeing as this app haven't been updated for awhile I hope someone else makes a new one :)

It's not busy with designs and colors, easy on the eye, and easy to use. A trick though is that it will not highlight when you've placed a number in the wrong location. For example, you can put 3 in any random box that does not interfere with another 3. Suppose that box is supposed to be a 7. It will not highlight that you misplaced the 3, even though it really is in the wrong spot. It's like if you were playing with pen and paper. You won't know you have a misplaced number until it's too late. I like that.

UI is not looks good.looks messy. Once done with the one number color would be change automatically. For instance If filled number 3 in nine places. The number 3 color is in still orange. I suggest u to change the color immediately once after he filled nine instances.

I dont want to play using any other Sudoku app but since the Android M update in my S6 Edge the in game options menu has disappeaered. Please update. I am missing my Sudoku on the work commute.

Some sudokus cannot be solved without guessing at some point so this app needs a way to backtrack when you guess wrong. Like, say, setting a new colour for the cells you have filled in from the guess onward. That should be very easy to add.

Like others have said - been playing this for years, recently updated android software on my Galaxy S6, and now the menu is gone. Makes the app just about useless. I am sad.

Some puzzles need to be solved by trial and error. Getting additional puzzles doesn't seem to work. It would be nice to be able to reset these puzzles. I just uninstall and re- install otherwise very enjoyable.

Good! Clear,plain interface; easy to use; several options for number entry. More puzzles available. Small app; minimum permissions.

This is a good Sudoku game, with great interface and no bugs. I only wish that it would sort the puzzles so that unsolved always go to the top.

I tried several Sudoku apps on my new tablet and like this best. Being able to download additional puzzles is a huge plus, and the interface is very good. A couple suggestions: I use the SN layout and would like to see larger labels on the number keys. I'd also prefer to keep the count of number uses visible after that number is selected. Also helpful, since some game downloads have 100 puzzles, would be a filter on the selection screen to show unplayed puzzles only.

There are far too many sudoku apps on Android and many of them are ghastly. This one is the best by far that I have seen.

Has issues on newer versions of android. Screen flicker on S5 neo running Android 6. Was fine on android 5.1. Need to find a modern alternative.

Excellent user interface, a choice of input methods and fair range of puzzles and all truly free, not even any adverts - superb app.

Have spent many happy hours playing sudoku on this game - love the lyaout, setup, etc. Was disappointed to "lose" the settings menu on my Galaxy S5. Then I "found" it by happy accident when I long-pressed the recent apps button - you know - the one that used to be the context button. Voila! A Settings menu!

The interface is simple and clean, the ability to grab new puzzles is wonderful, I love it. The reason for only four stars: the game uses more battery than most of my other games, when I would think it would use less (this may be a perception issue on my part about how much work the game must perform to fill in potential numbers...).

I love this app, but the menu button (import/export, etc.) won't work on my new S7. I haven't been able to find a way to work around the lack of a menu button on the phone that works with this app. HELP

Been using it for years but just changed phones and is no longer compatible. Needs to upgrade for latest Android versions.

Beautifully crafted for touch screen input. This is the best sudoku I've played on any computer platform, let alone android. Congratulations to the developers!

Why oh why oh why can't I find a Sudoku that will allow me to highlight rows and columns? My very very old palm pilot had a game that did just that. Really helped me learn to play, and it's faster to see patterns, double check yourself. So hard to find now. Few games

So, this is the best Sudoku game I've found but I can't get to the Menu on my new NOTE5. Please, please do something to fix this.

With new Note 5 the Recent Key no longer works in puzzle as a Menu Button. Can too please fix that? Otherwise, 5 stars. Excellent application. Super smooth GUI. Thanks-where can I get more puzzles? Update. Can't believe I have been playing four years. It's still the best for ease of use and reliability.

Toggle option good. Allows you to put 2 numbers in one square if not sure which.

I played less then 10 games out of 30 and they already started repeating (same sets just slightly tweaked). Didn't like that.

Great layout. Fits my needs/addiction. Been playing it for years. Downloading more games is a cinch. Although, I would like to see an option to be able to reset all the puzzles at once. Captivate, Samsung S2, S3, S4, Note 5

Of all the sudoku's I've tried I like this the best. No ads, clean interface and has a checkpoint feature. You can add your own puzzles easily. Keep up the good work.

Can't find just sudoku. All have hints, colors, embellishments galore - bells & whisles. It's a simple, elegant game all the add on's aren't needed. How 'bout playing music every time you get a box right?

I like to play sudoku but as i started using this app, i discovered not all the puzzles are solvable and the app has not updated once since i downloaded it/

Changed my phone to the galaxy s5, and reinstalled it, but the game won't give me a menu. Can't set a checkpoint, replay a game, nothing.

Samsung Tab S app has no access to restart, set check point, etc?

Does what it says, has a few different options for entering numbers so you can choose the one you like, and is open source. Can't fault it.
