Inappropriate ads!

*** update*** the developer contacted me and claimed to have fixed the ads. I have not seen an inappropriate ad since. Thanks! Other than the problem with the ad, the game itself is very fun and addicting. ****
I used to love this game, but recently I’ve been getting ads for a game that is sexually explicit. My children like to play this game and now I can’t let them. I’m afraid I will have to delete the app, I’m just not ok with my kids seeing ads for a game that shows people in bed together and asking if they want to join the couple in bed. Disgusting.

Developer Response

Apologies for facing such a negative experience with the game.We have updated our ads for filtering such explicit contents for young users.


Fun at first

In the early levels it's fun and challenging but then in the later levels the timer is too fast. I was only getting about 30-40% done before it ran out. Even when I cheated by pausing it and solving it outside the game and then putting the answers in as fast as I could, I could only get 70-80% done. I'm not going to spend gems to get more time on every single level, either. There are more fun Sudoku games out there. Deleted.
