Really enjoy the game, but game time to ad time ratio too high. Maybe 5 seconds playing, then another 5-15 seconds of ad time. And it's every time. And ads don't recognize the No Sound options in the game and come blasting through (at night, at work, etc ) if I forget to turn down my volume before starting the game. Hard to tell the boss you aren't goofing off then! Uninstall...

Hi! It's a pity to hear about your unpleasant experience with ads. Unfortunately, we cannot remove all ads. We need ads to support the app and make it available to everyone for free. We hope you can understand that. If you wish to stop all ads, you can choose to remove ads. You'll never face any ads afterward.

Starts out every few games there's an advertisement. Then it goes to an advertisement after every short game. It takes longer to watch the advertisement than to play the game. Sometimes people complain about ads and it's not as bad as they say so I try the game. This is as bad as they say. Sure the developers get paid buy the ads watched. But you can't get paid if people don't play your game. Deleted.

Hi! We are sorry to hear that you had a negative experience with the app and that you removed it. Ads are one way for us to monetize the app when we endeavor to design, code, and perfect it. We also sincerely suggest that you choose to Remove Ads. Thanks for your understanding!

I'm used to the ads in all games and I play many with the ads, BUT there are entirely too many in this game. AND full length after each and every puzzle and any other ways to slip it in. I love the game and would like to keep it, but I think I can find another one that will at least let me play a few rounds without an ad! Sorry, I wanted to like, but when the time spent on ads out runs playing the game 3times as much it's no fun and a waste of the time I have available to play games. ☹️
