Bombarded with ads

I loved playing this game prior to all of the ads. Now, you have to watch an ad before and after every board

Interrupting the game

If I had given this game a review a few weeks ago I would have given it 5 stars. Today it gets two because I can’t even finish a game without an ad taking me to the internet!!! I can deal with it before and after, but not during!!!

Intrusive Ads - Genuine Curiosity

I hope it’s a glitch, but the game has started to abruptly take me to the internet for an ad. Out of curiosity, is your company hard up for cash so you’re now pushing ads in the middle of games to generate more revenue (instead of only at the beginning or end of a game), or is it simple greed?

Used to love it

I stayed with it when all my records and hints disappeared. I stayed with the incessant ads at the beginning and end of games. Now I click on a square to answer and I’m taken to an add. Can’t even play.

It’s a good brain game. I enjoy it but all the ads are frustrating.
