The invention consists of eliminating the inner central shaft of the drum in order to allow a more homogenous mixing of the balls such that the chances of the balls being winning balls are not dependent on the position that they may occupy before the drum is rotated. To that end, the ball mixing blades () are integrally attached to the inner face of the structure of the drum. Not only does this structure allow mixing the balls better, but it also simplifies maintenance work on the device, in that it includes respective outer shafts () that are easily accessible without having to disassemble the drum in the event that the pin that links it with the mechanism for driving the rotation of the drum breaks.

Ball whirling device for recreational games of chance

The board game (,), with the conventional pivots (,) determining the labyrinth-type course for the ball, is framed by a circumferential channel (,) in which there is a ring (,) provided with at least one lateral, internal opening (,) so that, upon the rotation of said ring (,) each housing (,) is placed, in sequence, opposite a lower opening (,) of the circumferential channel (,) in order to receive a ball (,) and opposite another upper opening (,) via which the ball returns, under gravity, to the game zone. In addition, in the passages (,) which the ball or balls (,) has or have to reach at the end of each play there are arms or stops (,) capable of closing off said passages, retaining the ball or balls (,) for a sufficient time for the player to be able to observe it or them and subsequently allowing it or them to fall, to which end said arms or stops (,), crossing the board (,) via transverse grooves (,), are fixed in a monobloc manner forming a type of comb (,) which can be actuated transversely by an electromagnet (,).
