2 stars because the base game is okay. This is the only game i have deleted within 5 minutes of playing. I reached level 18 and by that point had realized i had also watched 18 ads. Thats right. To play one 30 to 60 second round you also must watch an ad. Unfortunately the game isnt good enough to justify paying for it to remove the forced ads every round. Not worth the headache of trying.
