====Air mix====
Air mix machines have a fan in the bottom that blows the balls around. A valve to a tube opens, and the balls that are blown into the tube are the winning numbers. The balls are evenly weighted and are usually locked away in vaults when not in use, in order to prevent tampering.<ref name=":0" /> Machines of this type are used for many "daily numbers"-type games, as well as the pan-European game [[Eurojackpot]].

Though similar in style to the latter type of "air mix" machines, those currently used by the American [[Powerball]] game do not use air mix; it is more in tune with a "gravity pick" machine, with the mixing paddles at the bottom of the machine. As the mixing paddle slows down, the ball lands on a pedestal, where it is carried to the top of the machine and then pushed onto the tray. On rare occasions, a similar machine is used in a "pick 3" or "pick 4" game.
