The game itself is a 3.5 - 4 star game. Just do yourself a favor and put the game as a paid purchase on the store. Aside from the optional ads, the amount of shameless forced ads that are shoved down your throat while playing is disgusting. I'm completely fine with SOME ads as a way to make revenue, but the ads kept playing after every single tile I unlocked. I'm pretty sure I've watched over an hour of ads in my 3 hours of gameplay, which I endured just so I could write this review. Ugh.
