Community Insight:
When we just want to sit down and relax we also want some fun so we pull out our phone and play it also helps our mind unwind!! Thank you so much for this opportunity.
We love sudoku! We think it really challenges your brain & the notes option is so helpful! When Im unsure we use the notes feature & when we figure out one & the notes auto takes it away if theres one in the same row, column, & box! Thank you creators. :).
Fun and easy to play , thank you .<3.
Glad its free but you have to keep opening and closing to get past the adds.
Great way to excercise your brain.
Im really enjoying your game platform. Nice and simple layout, quiet after turning the sounds off. Perfect for those of us with sensory overload issues. Sudoku is very relaxing and fun. Only took a week to work up to the highest level. As an inveterate crossword enthusiast, it is refreshing to solve these number games.
Enjoy playing the games. We understand why there are ads in the free version but being forced to wait through the ads with multiple steps to close them is about to make us delete this app.
This could be a good game app if it didnt require updates after 30 seconds of play. Very frustrating.
The game used to be even more fun earlier when there were no add.
Simply too easy. Let us make mistakes with our notes. Also, not a fan of the slight lag time before the numbers appear. We can hit the keys to make notes on an entire row before the 2nd box displays.
So many ads. Want to respond to a Text or another alert? Watch an ad. Not seeing enough 2 Minute ads. This will be your app.
We tried to report a problem with your game but the website is not cooperating! We play Cross Math in the Sudoku app. We are at level 896. After inputting numbers in all of the blank spaces there is number left over. No empty spaces. We have hit the hint button several times and watched the ad each time. The game never tells us what to do with the extra number. It will not go on to the next puzzle. Please tell us how to advance to the next game or get rid of the extra number. If we knew how we would attach a screenshot showing the puzzle.
The games are becoming more complicated so that our challenges continually increase thats great.
The essence of everyday life is measured within the misdemeanors of pain, pleasure, and passion.
Perfect classic sudoku game. The best on the App Store. Like the app and the ads are tolerable unlike most free games. That said, we find that if we get stuck and need a hint, the watch an ad to get a hint feature rarely works. Watch a very long ad thats nearly a minute long, with three or four next or (X) you need to hit to finally be back to the game and you still have no hint available. The same apoes if we dont complete the daily challenge and want to watch an ad to play the previous days challenge. It would be less aggravating if the ads werent for the absolute worst garbage possible. Still a 5 star app with that annoying bug.
Our favorite things on earth.. What a trifecta.
Played 3 times. To much ads, and for too long. Deleted.
Awesome so far. Just started playing. Still on the easy mode.
We simply love to play Sudoku almost as much as we Quilt.
It brings us calm , when we are in stress situations.
Really enjoy this game! Ive been playing it since we retired, thank you.
This was a perfect sudoku game. But they change it and change it. After the latest update the numbers are too big to fit in the squares. We have been thinking about paying the annual fee. Glad now that we didnt. Im off to find another app. We are uninstalling this one.
The game is challenging, makes you think and remember. It is a lot of fun.
We can do this!. Really nice app.
Good brain exercise for 59 year old.
This is a very consistent app, with acceptable amount of ads and otherwise is exactly what you want from a Sudoku app. Lots of statistics too! There were two things we were going to complain about, but refreshingly both can be disabled in the settings (we dont like auto mistake checking, and the auto-finish button covers up some of the cells making it impossible to not use).
Level number 41 in killer, sudoku easy level cannot be solved due to an incorrect placement of numbers.
We have been playing this particular app for quite awhile. Everything was fine until a few days ago when suddenly you were putting ad after ad between every game. We uninstalled yesterday but found we missed the game so we reinstalled just now. We played one game in a tournament and then there were 3 ads. Not just regular ads, but 60 second ads. We deleted the app during the 3rd ad. If you find an inordinate amount of deletions you might want to look no further than the number of ads with which youre plaguing your customers.
We like the gaming features, but good grief the ads are beyond frustrating. Two or more minutes to wait through an ad between each game, especially when its the same ad repeatedly, makes playing unbearable.
The expert level and the other levels feel pretty much the same.
We would like to play this game and listen to music at the same time however this stupid game always pauses our music no matter what we do.
Way to many ads. Every 5 or so minutes would be one thing, but ads after every single game is ridiculous and the whole reason we got rid of this.
Puzzles truly can be solved using advanced techniques and hints layout techniques used. By far the best app if you are learning advanced sudoku or are already looking for the hardest puzzles out there.
It is so simple and easily explains how to play sudoku it is so awesome try it for yourself.
Entertaining. Please dont punish good performance.
The add for this came up when we were playing a different game. Said ad free for this Sudoku. NOT TRUE. Its lousy with ads so we deleted it.
We love sudoku and this is the best app freaking EVER. Definitely the ONLY one we will ever use.
We played a different Sudoku app for years. Recently they started showing many ads during each game. Im glad we switched to this app which shows very few ads.
He tenido otras y no se puede comparar lo mucho mejor que es esta, es muy completa y con sus herramientas increbles :) es mejor que incluso algunas con mayor cantidad de descargas.
This is easily the best Sudoku app on the App Store. Our only complaint is that there is no orientation difference. We play on our iPad and we are forced to play in portrait mode and we would much rather play in landscape. It makes it difficult to play in portrait when we charge our iPad otherwise it is a very good app. The ads still let us listen to music or we could just pay to get rid of them. It is still worth it and compared to any other Sudoku app. We hope the developer see this since we think it is a easy fix and it would change our rating from four stars to five.
Love the game and the tips. Ads are so repetitive and sooo often.
When we get to the nightmare and expert levels, it seems like a fair amount of puzzles dont have the information to solve without a hint. Many of these hints just fill in the note numbers, and you can solve the puzzle, but theres not enough information for you yourself to fill the note numbers the way the hint does. Beyond that, theres usually a point where you have to guess at least one number to solve these puzzles which defeats the purpose of the game. Sudoku is not a guessing game. Since hints cost ads and ads make money we guess it makes sense why its built this way but we have to admit it feels a bit deceptive, and takes away from the enjoyment of sudoku. We guess Ill go back to using the books.
Really easy and fun to do when Im having a mental break down.
This game is very good at helping us improve our critical thinking.
This sudoku is an excellent and stimulating adventure.
This is entertaining and it works our memory also gived.us something to do while we are waiting.
updated to 5 stars because they fixed the bug in our initial review Perfect classic sudoku game. The best on the App Store. Like the app and the ads are tolerable unlike most free games. That said, we find that if we get stuck and need a hint, the watch an ad to get a hint feature rarely works. Watch a very long ad thats nearly a minute long, with three or four next or (X) you need to hit to finally be back to the game and you still have no hint available. Without that it would be a 5 star app.
We really believe this helps our mind stay active.
Love this sudoku – play it a lot. But we noticed that the app takes up over 7 GBs – only 230 MBs for the game, and over 7 for documents and data. What is taking up so much space on our phone in this app.
We love this game and have played for a number of years. Recently the ads have become offensive. We dont like sex ads and dont appreciate sitting through one to play. If this no we will be uninstalling and getting our daily sudoku fix elsewhere. We understand the need to be paid but ads are a choice and is owner:developer choice and this was a poor one. Thus our rating of 4 instead of 5 stars Update.. We received a reply to our review that showed an answer from someone who must not have read what we wrote. Sorry for the inconvenience our issue was ad choice. Not the game itself. We reduced one star for such a nonresponse.
