Player Experience Highlights
Community Insight:
Other games like sudoku master has much better notes features.
The definition of a Sudoku puzzle is that it has one and only one solution. The last puzzle we did had more than a dozen unique solutions (we stopped counting). We were using the paid version.
Evil is still too easy, but most diabolical are only solvable if you guess, know the x-y wing solution or its a bingo. Ridiculous! Id like to find a solo gave thats hard but solvable with human logic.
Im learning a lot about math and its educational.
These are definitely solvable. Ads are really annoying though.
Once we start we cant put it down.
This game keeps us sharp and relaxes us when we are anxious and stressed out. We live it.
So easy to use. Move up the levels as you get more experience. Leave it and come back. It is waiting for you. The timer makes it fun and challenging. Relaxing. Love it.
So fun choose your mode and get playing we could do it for hours if we had the time, thank you sudoku.
We like the game, we wish the boxes were more defined. Sometimes its hard to tell what box Im working in.
The latest upgrade ruined the features of the App. Please review and fix bugs.
Great game but too much app adds.
Great as long as you pay to remove adds.
We used to buy the books but would do the easy and a few of the mediums and throw the book away here we can play the easy as long as we want . So thank you Im having fun , your medium has more numbers than the books did , so we will be doing mediums more on here as well . Im 75 years old and Im trying to keep our brain active.
If you enjoy constant lock up, this is aggravating enough. If not, find another game provider. We enjoy this game.
Ive been playing Sudoku about 17 years. Love the game and since we found this app, its been the very best experience. After paying a minimum fee, we can simply scan and scan for the right numbers without stopping for an ad. We also love the ability to select the colors we prefer to see. Everything about this app is intuitive. We have continued to download and use it on each successive cell phone. If you love Sudoku, youll love this wonderful app.
We love this game. We wish we could get it for android phones.
Even better with less commercials.
We want to save the game, so at any point that we have made incorrect changes, we can return to our saved game.
Best sudoku app!!! The ads are non invasive and the gameplay is simple and easy on the eyes as well.
Challenging, fun game. Great for the phone.
This app could use an error check for corrections.
App used to be pretty good. Really liked it, but now it has ads all over it and it blocks you from playing for too long. Easier to just walk away.
No bugs no problems just confused it says there are ads but Ive never seen any.
We dont like kids games! We prefer strategy games that occupy but do not tax our brain! Sudoku calms us and gives rise to a proper nights sleep! When we need toVeg! We need this game! Our OlLady does MahJong.
First, visually annoying. Dark background with dark borders make it difficult to see. When a number is selected it would be nice to highlight all the numbers too. Other games do this. Finally, when a row or column is filled out it would be nice to flash or somehow indicate completed. And when the board is completed correctly, huh? Nothing? Wow. Update: this game is the worst sudoku Ive played. And Ive played a lot.
Great brain builder to play everyday.
This is has been our go to app for Sodoku. Unfortunately, we will probably be looking to other apps as the highest difficulties require forcing chains which we dont particularly enjoy. Until we can sift through a ton of other ad ridden Sodoku apps, Ill probably continue using this app.

The undo button should be replaced with a backspace or deletion of numbers should be allowed on the cells directly . Otherwise a great board game simulated.
Ive tried many Sudoku games – this has a very clean layout and how to play is very straightforward. By far – the best.
It is fun, challenging because of the different levels offered and keeps the mind involved.
We never dreamed we would be hooked on Sudoku.
We enjoy playing Sudoko, because helps us to keep our mind active.
Very clean, no pop ups or gimmicks. Elegant. Multiple difficulty levels. Worth paying for.
Its just basic soduko. Thats why this app is great. The advertising does not distract from game play and its free.
This game MAKES us think. Problems never solve themselves. Keeps our mind off trump! Helps our organizational skills. Keep things in order. Keep our mind off GOPs destruction of the USA.
Easy to play. Nice features. The best app.
We think that there is a big jump between the two most difficult categories of the Sudoku- is it too big a jump.
It was perfect then they made ads after the game or sometimes to load. Its easy to by pass. -but just annoying.
Hate they interruptions between games, especially the load ones.
Started out great. Recent update causes obnoxious ad music to play during game.
Recently added obnoxious music while playing the game. And most ads now are for stupid violent or anti-wonen sexual games.
We like that we can keep it easy and not get frustrated like we do with other games. (some games that we really really want to play have these insanely difficult puzzles that you have to solve in order to be able to move on with the story and we absolutely hate that).
We used to buy the books but would do the easy and a few of the mediums and throw the book away here we can play the easy as long as we want . So thank you Im having fun , your medium has more numbers than the books did , so we will be doing mediums more on here as well.
Love the fact they dont interrupt the game with commercials or banners. Fine with seeing them between games.
We LOVE THIS GAME ITS THE FIRST AND LAST GAME THAT we PLAY EVERY DAY THANKS.
We love Sudoku because it gives us something to do when Im bored.
This version of sudoku is pretty good, you can easily choose the desired level and create notes. The settings allow options for auto filling the squares ( or not). It would be better if it were easier to get in and out of note mode, and also to know whether or not the game is in it. We paid $2 for the ad free version.
We give this app a 4.9 rating. The only thing it needs is a hint option. It has great settings, note options, and advanced difficulties.
