I'm around 2000+ levels in and I could watch ads to help pass levels everyday. A couple of days ago I spent 99 cents for 100 gold bars plus a ton of other boosters. Thought it was a great deal even tho I typically NEVER pay to play. Issue is that now every since they got my $1 they don't offer me the chance to continue by watching ads because I've apparently been flagged as an "account willing to pay". I searched online and found a reddit forum where everyone is saying the same thing. Now when I can't pass a level they only give me a chance to continue if I pay gold which I don't have any refuse to buy anymore. I will delete the app if it stays this way and wanted to warn other people before they get trapped also.
