Steals your money
DO NOT PURCHASE. They sneakily updated into a subscription model. Made an in-app purchase for a previous version to buy packs. Now looking back at the history of my subscription they changed from a permanent in-app purchase to a 1-week only purchase. Very sneaky. Such a shame because it's a good social game with high recommendations from friends. Now they're just greedy. Not worth the money and highly unethical.
