Have you ever played bowling vertically?

Now you can do it, thanks to your Windows Phone 7 and to Gravity Bowling, or GravBowl as we call it among friends.
Ten challenging and amusing tracks are waiting for you.
Direct the ball by moving your mobile phone and try to put down as many pins as possible.

Will you achieve the perfect game?
