A lot or a little?
Parents need to know that Hungry Shark Evolutionis an arcade game for iOS and Android devices. As a shark, you have to eat anything and everything you can: scuba divers, crabs, and all kinds of tasty fish. Doing so does spill their blood, of course, but so does hitting a mine or getting bitten by another shark or seal. Otherwise, this has no other objectionable content. Commercially speaking, you can earn in-game currency by playing, or by buying it in the in-game store, which is then used to keep playing, buy new sharks, or upgrade the sharks you already own. You can also earn this currency by watching ads.
