Isaac Newton’s Gravity is the latest iPhone and iPod touch offering from Namco Networks, makers of Pac-Man and other hit arcade games. It costs $4 and is available now from the App Store.

Featuring the famed British physicist, mathematician and astronomer Isaac Newton, this game is (perhaps appropriately) a physics-based puzzler. Your goal is to arrange objects to hit the trigger and win each level – there are 50 in all. If you get stuck, Sir Isaac himself will provide you with hints.

You can also download additional levels, create levels of your own, share your achievements on FaceBook, and challenge friends.

System requirements call for an iPhone or iPod touch running iPhone OS 2.2.1 or later.
