Future Games of London have made all three paid versions of the games of their Hungry Shark series freeware.
You can unlock the full game with In App Purchases or via GetJar Gold rewards which can be obtained for free by downloading some free apps and games or by buying some credits.
You can also buy the full game directly from within the app via an IAP.
The games are of a unique genre and allow you to play as a ever hungry chomping monster, A shark. Actually it is not just a Shark, there are various in game upgrades, which allows you to upgrade your abilities and even choose different species of Sharks.
The games also have an optional touch control system for those of you who hate tilt controls,(including me). You can also play your way to the top of leaderboards and unlock achievements, etc.
If you are looking for a gem with good graphics I’d recommend Hungry Shark 3 over the other two. And there is a fourth game in the series which has the best graphics and has great missions to complete.
