Free fall games are games that come in different forms. Sometimes, you jump out of an aircraft by parachute, and after the phase of free fall, you have to deploy your parachute and arrive first on the ground.
Sometimes, you must practice a more futuristic race as in Xtreme Vertical Racer. You have to vertically move and stay ahead of the others passing through rings that can give you powers of acceleration or bonuses that will help you to finish first.
In free fall games, you should always arrive before others.
