A transparent, automatic ball blower configured to generate random outcomes for a game by air-mixing Ping-Pong-style balls in a mixing chamber. During game play, the balls extracted from the mixing chamber via an extractor pipe are subsequently carried by a computer-controlled, motorized ball carrier mechanism to an inlet of a ball accumulator compartment. The ball accumulator compartment may be located proximate to the ball mixing chamber. The ball carrier mechanism moves and drops the extracted balls, one-at-a-time, into the ball accumulator compartment. The balls fall into the ball accumulator compartment by means of gravity alone. The balls fill the ball accumulator compartment which, in one version, accommodates a single vertical layer of balls allowing visual inspection of the balls. At the end of game play, the balls are released from the ball accumulator compartment into the mixing chamber through a computer-controlled, motorized ball release gate.

A lottery game comprises a hollow canister, game pieces, a presentation mechanism, and a computing device. The computing device causes the game pieces to mix in the hollow canister. A first game piece is moved from the hollow canister to the presentation mechanism via a tube. The presentation mechanism comprises a first disk and a second disk, each with a plurality of holding cylinders. The first disk rotates to align a first holding cylinder with the tube, and the first holding cylinder accepts the first game piece. A second game piece is moved from the hollow canister to the presentation mechanism via the tube. The second disk rotates to align a second holding cylinder with the tube, and the second holding cylinder accepts the second game piece. The computing device determines a first identity of the first game piece and a second identity of the second game piece.
