With movement of a platform relative to a slot, a discrete burst of air is delivered to a stack of unshuffled cards, thereby pushing a single card through the slot and into an area where shuffled cards are to be delivered. It is contemplated that embodiments of the invention will include means for the delivery of a discrete amount of air in response to a computer signal, it is further contemplated that embodiments of the invention may include rollers that are engaged to spin and grip a card that is pushed through a slot by air. It is contemplated that embodiments of the invention may include a set of perforated guiding members that include a plurality of perforations that are sized to permit and diffuse a predetermined amount of air by volume and pressure. ## Claims ### Claim 1 A mechanical shuffler comprising: a generally planar base, a platform sized to receive at least one deck of unshuffled cards, the platform movable in a direction of travel parallel to the generally planar base, a first electrically powered motor mechanically coupled to the platform and configured to move the platform in response to a first signal, a slot positioned adjacent to the platform and sized to receive a single card from a deck of unshuffled cards wherein the deck of unshuffled cards rests atop the platform and wherein the slot is in communication with an area for the delivery of shuffled cards a primary air manifold attached to a manifold plate, the manifold plate having at least one hole configured to deliver a burst of air to at least one edge of a playing card, the hole configured to deliver the burst of air in a direction toward the slot to cause the playing card to be moved through the slot to the area for the delivery of shuffled cards. ### Claim 2 (depends on 1) The mechanical shuffler of claim 1 further comprising a computer, the computer including a processor, display, and user interface. ### Claim 3 (depends on 1) The mechanical shuffler of claim 1, the primary air manifold configured to deliver the burst of air in response to a second signal. ### Claim 4 (depends on 3) The mechanical shuffler of claim 3 further comprising at least one roller, the roller configured to spin in response to a third signal. ### Claim 5 (depends on 4) The mechanical shuffler of claim 4 including at first optical sensor, the first optical sensor configured to send a signal to the roller. ### Claim 6 (depends on 1) The mechanical shuffler of claim 1 further comprising a secondary air manifold. ### Claim 7 (depends on 6) The mechanical shuffler of claim 6, the secondary air manifold including at least one air inlet and a plurality of air outlets, the plurality of air outlets configured to deliver a burst of air to at least one edge of a playing card. ### Claim 8 A mechanical shuffler comprising: a generally planar base, a platform sized to receive at least one deck of unshuffled cards, the platform movable in a direction of travel parallel to the generally planar base, a first electrically powered motor mechanically coupled to the platform and configured to move the platform in response to a first signal, a slot positioned adjacent to the platform and sized to receive a single card from a deck of unshuffled cards wherein the deck of unshuffled cards rests atop the platform and wherein the slot is in communication with an area for the delivery of shuffled cards, a chute located in the area for delivery of shuffled cards, the chute including a plurality of perforations, the perforations configured to diffuse a burst of air of a predefined pressure and volume towards the slot to cause the playing card to be moved through the slot to the area for the delivery of shuffled cards. ### Claim 9 (depends on 8) The mechanical shuffler of claim 8 further comprising a primary air manifold attached to a manifold plate, the manifold plate having at least one hole configured to deliver a burst of air to at least one edge of a playing card, the hole configured to deliver the burst of air in a direction toward the slot. ### Claim 10 (depends on 8) The mechanical shuffler of claim 8 further comprising a secondary air manifold. ### Claim 11 (depends on 10) The mechanical shuffler of claim 10, the secondary air manifold including at least one air inlet and a plurality of air outlets, the plurality of air outlets configured to deliver a burst of air to at least one edge of a playing card. ### Claim 12 (depends on 8) The mechanical shuffler of claim 8 further comprising a plurality of rollers, the rollers configured to spin in response to a first signal. ### Claim 13 (depends on 8) The mechanical shuffler of claim 8 further comprising at least one optical sensor, the sensor configured to detect the presence or absence of a card in the chute. ### Claim 14 A mechanical shuffler comprising: a generally planar base, a platform sized to receive at least one deck of unshuffled cards, the platform movable in a direction of travel parallel or normal to the generally planar base member, a first electrically powered motor mechanically coupled to the platform and configured to move the platform in response to a first signal, a slot positioned adjacent to the platform and sized to receive a single card from a deck of unshuffled cards wherein the deck of unshuffled cards rests atop the platform and wherein the slot is in communication with an area for the delivery of shuffled cards, a primary air manifold attached to a manifold plate, the manifold plate having at least one hole configured to deliver a burst of air to at least one edge of a playing card, the hole configured to deliver the burst of air in a direction toward the slot to cause the
