User reviews

Great App but…

I love the app; it’s one of the best implementations I’ve played. But the full screen ads make it not worth it. Please, PLEASE GIVE US AN OPT OUT!

Disgusting ads

This actually a great game and I will revise my rating if the ad for 3d wool escape is no longer shown. It’s utterly disgusting.

The ads kill this game!

Used to love this. The game itself is great BUT ads before after and during the game, some are a full 2 minutes and more. I’m done.

third time this week where ad is just blank black page

And then can’t get back to game… so have to delete app and reload. Very annoying
