Honestly, I would give it 5 stars if the ads didn't block the game 9 out of 10 times. They get stuck, with no way to turn them off unless you press on the screen, then go on Google play. But when you click back, the game doesn't load and you have to restart. I would honestly watch ads for more coins if it didn't get stuck as much. There also might be a truth to that the game kind of seems it doesn't let you win sometimes as you progress. Otherwise, fun game with great potential.
