A Barrel Roll is an aerial maneuver in Asphalt 9 that sends the car flying in a corkscrew trajectory. It can be initiated by jumping off curved ramps at high speed. A 360 is another trick in Asphalt 9 during which the car spins in the air or on the ground. It can be triggered by quickly tapping the drift icon twice in a row. Both these tricks reward you with nitro during a race. Skilled players can perform several Barrel Rolls or 360s in a single jump, which is a solid strategy with which to quickly fill up their car's nitro bar. Try to perform a 360 while racing next to your opponents to knock them down and refill your nitro bar.
