Ratings and reviews

Sure, it's fun. But the ads are getting unbearable. Some of the ads you can't even skip or exit out of. Others literally leave you on a black screen, where of course you can't exit out. When you press your screen during the complete blackness, it doesn't even take you to the play store to download so it's just a big waste of time. You basically have to watch an ad to improve at anything in this game so money is almost useless. Overall, it's irritating but still somewhat fun.

Surprisingly addicting for a game that's mostly ads (can't use airplane mode). Ads required after each game, ads to get bonus coins, and ads to not lose your achievement award. Then multiple ads to open up EVERY sales table, ads for every possible aesthetic, and ads to play the summer level. I'm tired of watching ads for every tiny thing! It doesn't tell you WHY you're upgrading with ads, what any add-on is worth, to boost your score. Also, the doors need to be more visible.

I suspect this game exists exclusively to generate ad revenue. I played 100 levels (usually with wifi/data off) just the see if anything changed... it didn't. If you play the first ten levels, you've seen it all. An ad plays after each sub-30 second round, and you are also prompted to watch them to unlock gems and jewelry which increase the amount of money you collect. Not sure why you would need more money because 80% of the unlockables can only be done so... By watching multiple ads. :)
