Jun 12, 2014 - Quite possibly the most realistic bowling app available! Mach Ten announces 4D Bowling Ten Pin Classic. The game utilises the sensors of the iPhone, whereby the action of swinging the phone like a bowling bowl will determine the speed, direction and spin of the ball. The motion sensors have been calibrated to take into account both the speed and the deviation of the swing. It is also possible to spin or turn the ball. 4D Bowling Ten Pin Classic is designed to appeal to all ages.
