Disclosed is a ball blower apparatus for facilitating games of chance. The ball blower apparatus has a motor-driven ball carriage mechanism that captures air-ejected balls from a ball mixing chamber and carries the captured ball to an inlet of a ball return tube that extends downward to a bottom of the ball mixing chamber. Captured balls travel down the tube under air pressure generated by an air blower. The air pressure also prevents the balls from electro-statically clinging to walls of the tube. The balls may be bar-coded and scanned by a barcode reader while being handled by the ball carriage mechanism. A computer interfaced with the barcode reader automatically controls the operation of the ball blower including the operation of the carriage motor, air blower(s) and a solenoid that controls the egress of balls from the ball return tube into the mixing chamber. A TV camera may also be utilized to capture and visually display numbers associated with the balls.
