"Ads when I open the game and after every game. Plus the ads are getting longer and longer, not to mention it is nearly impossible to close app without opening an ad window. I use to enjoy playing A1 Factory and now ready to dump the game."

"The app previously was 5 stars. Now it`s lower due to its unskippable ads forcing you into the Play Store. Really unfortunate."

"Just about as great of a sudoku app as I could ask for. Ads NOT obtrusive. Super chill, as good as a book of puzzles but on the phone."

"Pretty good game. It`s hard enough, but not too hard. I`m not a Sudoku expert, but I`ve managed to play through the Level 5 games and I`m going through them again. It`s a good mental exercise once a day. It has quit on me twice, but I reinstalled it and started over."

"Finishing a game starts an ad from its maker for some of its other games. The problem is (1) it is about 30-sec long and (2) no cancel button shows up and eventually forces you to the Play Store. This drives me nuts because I don`t want other games (come on guys, take a hint). Yes, it is fair an ad of some sort shows up, but allow me to skip after 5-sec, for crying out loud. Game is good but not worth this. It is antithetical to AI altogether. I am deleting it and moving to other companies."

"Another great game from AI Factory... --- 2022/12/04 --- I decided to uninstall it, few days ago. The ads are too intrusive and annoying."

"Latest version is a bit buggy, and doesn`t record your time on some of the games (level 5 game 301, for example). Has the best controls of any in the store."

"While other decry the method this game uses in unmarking moves I enjoy the need to manually deleting unneeded numbers in the squares or rows. More akin to the original Sudoku books. It also makes you use your brain that way. As for the free version sure the commercials are intrusive but hey it`s free and at least you can fast-forward through most. EDIT- To those of you complaining about crashing, turn on the ``always on`` setting. You`ll get a popup about battery life, click ok and enjoy the game."

"Good game, but data hog. It used 600MB just for ads and what was after I turned off data half the time I played it. I have limited data and it consumed more than any other app this month. I will have to delete it."
