too many ads. I get used to the ads after you finish a game. but right in the middle of a game is ridiculous. 🤬

I give 2 stars because it's sudoku. but omg the ads..... ads everywhere. ads before ads in the middle while you in the middle of a game and after. if it wasn't for the excessive ads I'd give it more stars. not relaxing at all

Not for expert level players. I wanted to play at the top level (I am a strong player), but it will only let me play after 30 games at lower levels, then climb up to expert level. Why would you do that? Why would you stop expert players to directly access expert levels?! Don't have time to waste. Uninstalled, and looking for other option in play store.

Ads have gotten ridiculous. It used to have about 3 ads for every game played...before and after each game. This was annoying but tolerable. Now, they've added ads that pop up during the game itself every time you complete a number. The last game I played had 12 ads for 5 minutes of game. I am deleting this game as its not longer enjoyable or relaxing.

I enjoy the game but it has been crashing left and right. The ads will also freeze causing you to have to close and reopen the app and it does t save any progress. At this point I almost want to give up playing. It sucks when you've played for 20 minutes only to have it crash. I would definitely rate this game higher if the buds were fixed

Until a month or so ago, I would have given you 5 stars. Now, however, I'm on the verge of deleting the game. It was ok having ads between games, but now you're throwing 15-45 second ads multiple times in the middle of a single game. In fact, after posting this update, I'll be deleting the app. It's unfortunate because I like the features of the app but the ads are unbearable.

Ads, ads, and more ads....Started out enjoying the game but the ads are far too intrusive. After every game, sometimes even you turn your head and inadvertently touch a button on your screen, bang, another ad, then another one when you backtrack to the game. I get it, have to make money somehow when you have people like me who won't buy anything, but, scheez, enough already.

Love the game and the way the app is set up, however the constant ads are completely ruining the experience. And I was just thrown back to having to play through the easy levels after playing evils for probably close to a year. If I have to watch 5 ads just to get through an easy game, I just don't have that kind of patience. I'll be trying other sudoku apps and will probably delete this if I find something better with less ads.

I can deal with ads in a free version of a game, but the ads come multiple times while I am in the middle of a puzzle messing up my train of thought. It makes the game not fun for me and not want to continue playing. I would probably play almost every day if you put the ads at the beginning and end of puzzles. Instead i play once a month bc each time i get reminded of how much i dislike this apps ad platform. You are literally losing money on ad exposure bc people dislike your app for the same

2024/03/24...now they just got too greedy: I was content to put up with the ads and when making two or more mistakes. But as of this date, the makers have decided to require ads within the game when you're in a flow... There is now a required add when you complete one number and when you complete a second number. The subscription is too expensive for a game that is widely free worldwide.

The only way to get rid of ads is through a subscription. I'm not signing up for a recurring bill. One time pay is ok, but this is skeevy. Not to mention the app does not allow you to skip straight to the harder difficulties without playing the easier games multiple times first... I don't have the patience for this. I spend more time on ads than on the actual puzzles.

Battle mode is flat out lying to you. That is NOT the win/loss record of your opponent. How do I know? I am top 50. There is nobody with a similar record to mine for me to be matched against on the scoreboard, yet somehow it finds an opponent in 5 seconds every time. Now they just added an advertisement that pops when you complete a number. It's actively damaging the enjoyment of the game to cash in on the current playerbase. Stay away.

When I looked up Sudoku, there were many different ones. But after looking through reviews and it's description I liked how this looked and installed. I did not regret doing so. The way this game is set up is awesome with challenging puzzles+plenty of little thing to help. There's a pot of Sudoku games out there, but this one is certainly great. It lets you know when you get one wrong, but still doesn't give the answer thankfully and you do fail if you get too many wrong so it not too easy :)

This game has wayyy too many ads! I just wanted to play sudoku, and forget ever pausing your game, every single time you pause there are more unwanted ads! Also, this isn't as big of an issue, but it bothers me so bad! It always says, "you do this puzzle faster than 70.73% of players!" Or, "only 74.6% of people can complete this puzzle" why is it always in the 70's?!? I tried to leave a puzzle open so I could get worse than 70%, and even after 5 minutes, I still got 70 something better! Why?!?!!

It started out fine, but the ad experience gets worse over time, I think they think you won't notice if they do it slowly. It's gotten to the point now that it will just open an ad as if you clicked a link that wasn't there while you're just playing the game normally, totally insane, like 3 times in one 4 minute game, it opens an amazon page. I also have to close and restart the app after every round bc the game will be half off the screen, unplayable. This app is the worst.

Don't waste your time with this garbage app. These people are crooks. You can't complete a single game without 1-2 ad interruptions, and to buy the ad-free version is a subscription of $70/year... compared to a one-time charge of $5 in other sudoku apps, like the one from GamoVation. The only feedback I want to leave to these people are: DON'T INTERRUPT EACH PUZZLE WITH ADS! Give me The GamoVation Sudoku does make you watch a 5 second ad after most games, but that is completely reasonable!

Cody Watson

It's sudoku right, can't mess that up..... Unless every non-game action gives you an ad. Hope you never need to pause in the middle of a game, that's a guaranteed ad! And hopefully you don't need to pause multiple times in the same game, cause the pause button might as well be a "serve me up an ad" button. Ridiculous. Give me an ad after each game, not multiple within the same game just because I had the audacity to pause.

This is an ok sodoko game. It has an amazing mode where you play for the best time against other players. I love this... However, I found that there are clearly some players cheating. I don't mind losing, but to lose a match before you even have enough time to select your first number!!!! Its not common, but I have lost about about 5% of my matches in under 3 seconds. It's just not humanly possible for someone to make all those moves that fast.

The ads for this app are insane. I was mildly irritated with an ad after every game, but sure. I wasn't paying so why not. To get an add in the middle of a game is absolutely foul which is unfortunate. The app itself is pretty great, I started to play to earn rewards in another game and hoped to keep playing when I was done. Between the insane cost to get rid of the ads and the ads themselves, I will not be returning.

the puzzles are standard Sudoku far but my God, the ads. Before every puzzle, watch an ad. After every puzzle, watch an ad. Middle of a puzzle, watch an ad. It's constant! I get that a free app will use ads for revenue but they're constant and the buttons to close the ad are microscopically small. Then you have to hit three different buttons just to get out of one ad, so you can play the game for another 90 seconds before the next one comes in. Save yourself the frustration.
