Each week Apple offers a free app. This week is Bad Piggies from Rovio. Bad Piggies is a follow up to the super successful & popular game, Angry Birds.
From the App Store:
Create the ultimate flying/crawling/rolling/spinning/crashing device and pilot the pigs safely to the eggs!
The Bad Piggies are after the eggs again -- but as usual, nothing is going according to plan! Can you create the ultimate flying machine and steer them safely to their destination? Those tricky pigs have a few objects they can use, but they need your help to turn these into the perfect transportation!
With more than 140 levels, and free updates coming up, you have hours and hours of pig-crashing, exploding, and flying fun! Get three stars to unlock 36 more levels! HINT: Sometimes you need to play the level several times to achieve all the objectives -- try building a new device or steering in a different way to earn all the stars!
