Ads 👎🏻 An ad to play game 👎🏻
Recently, the ads have become intolerable I’m a fan of this sudoku app, which works well and provides outstanding hints, but recent ads have made it unusable. Some, such as the one for the sorting games, simply won’t go away without quitting the app. Others cover part of the tableau so that you can’t play. It’s incredibly frustrating, to the point where I’ve simply stopped trying. It’s a recent problem, and if it’s fixed, I’ll happily restore my 5 star rating
Horrible update Latest update ruined this app. Ads are long and intrusive! Played for literally over ten years but will now delete.
Ruined this game! I have used the brainium sudoku for years. It would appear that another company has taken over for them. The ads are so incredibly invasive, they last bloody forever, and you can't get rid of them. It just irritates me half to death, and I have just deleted the app.
Good I downloaded this app 7 years ago- it has survived all app purges. Good Sudoku app.
Sudoku with annoying ads I love using it to help me learn how to use logic to solve sudoku without the use of aids. However, it’s the really annoying ads especially tai * really hinders my wanting to go back to play.
Ads are out of control! I used to like this so but heads have gotten to be too much. Sometimes you have to watch the same as twice just to play one game. And sometimess the ad stalls do you have to restart and then watch another one. I’d buy the game but $12 is too much for an app that doesn’t explain all the hints. What is “trial and error”??? Seriously, how is that a hint? The app does a good job of explaining most hints, but some are just them giving you the answer with no explanation. That’s no fun.
Bad Sept ‘25 SW Update Oct ‘25 - Dropping from 5 stars to 3. The hints engine has changed and runs out of gas leaving you with “trial and error” as the hint. It used to be fantastic and would even show AIC solutions. Now it is so basic I’d like my $ refunded. I suspect the corporate profit focus shifted to jamming as many ads into the game as possible. I see a lot of comments with frustrated users deleting the game due to ad fatigue. I paid to remove ads. Still a nice interface but some dumb decision to change the hints engine has left this game truly disappointing. Sept ‘25 - This is the best interface out there! The AUTOFILL for notes is such a timesaver! The notes font is larger than every other sudoku app and actually readable without eye strain. The hints are very educational and allow me to then go and research new patterns so I’m learning and really advancing my skills. No 3 mistake limit. Easy to remove notes with one toggle. Other apps make you toggle each time you want to remove a note. The way it highlights for focus cells is the entire cell, not just a tiny note. Really enjoy playing this app.
Awesome brain puzzle This is a good brain puzzle and if you need something to do sudoku is where to go.
