Just tilt your device and turn the space upside down, defying the laws of gravity.Push the ball into the U by changing the gravity direction and tilting your device.HOW IT WORKS- Rotate your device to change the gravity direction.- You can change the gravity direction whenever you want.- Don't trap the ball when you change the gravity direction.- Draw objects, lines and polygons.- If you get stuck, tap the restart button.- Certain objects can change the ball's direction. And place!- Lines, springs, black holes. Each level has its challenges!Physics Drop Gravity is a free to play physics problem game with brand new levels that will put your spatial-visualization abilities to the test.Do you think you master physics puzzles?
