The invention herein describes a card handling apparatus used for automatically creating play-ready hands for use in casino poker games whereupon the apparatus may be programmed to accommodate a number of different game variations, and a variable number of players. The apparatus verifies the integrity of each deck before discharging the play-ready hands to a first discharge portal. Decks that do not meet verification criteria are isolated and moved to a second discharge portal. Non-faulty decks are moved to a metering station where they are metered to a card output tray at high speed while forming the play-ready substacks. Two decks may be shuffled, verified and queued within the device before commencing a game, or a second deck may undergo shuffling while play-ready hands from a first deck are being metered to the output tray.

A compact card handling device for use in casinos possesses a card input portal and two playing card discharge portals which are all accessible by a device operator. An optical recognition sensor cooperates with a microcontroller to interrogate the integrity of each card during an ongoing shuffling operation to discover unexpected cards, including unrecognized cards and flipped cards. Expected cards are randomized and accumulated into a stack whereupon those cards are thereafter delivered to a first discharge portal comprising a conventional multi-card shoe. Unexpected cards are immediately discharged to a second portal where they may be visually examined by the device operator while a shuffling operation continues. The input portal and the shoe are clustered conveniently upon the surface of a casino table while the bulk of the machine resides below the table surface.

The invention herein describes a card handling device used for automatically shuffling two card decks sequentially for use in a novel casino card game. The device shuffles a first deck and moves it to a first output tray and then shuffles a second deck which is moved to a second output tray. A microcontroller randomly decides which deck is to be moved to which output tray. A moveable hood obscures observation of the two output trays while the shuffling and deck movements are underway. Thereafter, the hood is moved to permit viewing and access of the two play-ready card decks simultaneously. One player is chosen as a game “HOST” and thereafter chooses which of the two decks to utilize for a subsequent card game whereupon the game “HOST” or other players may become advantaged by certain nonconventional cards.

A compact card handling device for use in casinos possesses a card intake portal and two playing card discharge portals which are all accessible by a device operator.
