A card shuffler that moves cards one-at-a-time from the bottom of a group that may be a deck in a deck-crib, to randomly designated single-card receptacles in a receiving or dealing rack. Either the deck-crib or the receiving rack is moved by a motor to align a receptacle, randomly selected from among remaining empty receptacles, with an outfeed slot of the deck-crib to receive each card to be moved from the deck-crib. A space is provided in the dealing rack in one embodiment, where a dealer's hand can reach cards and remove them from the dealing rack. A controller can cause the dealing rack to move so as to allow a selected number of cards to be removed by the dealer for a player hand or a dealer hand. A card reader may be included, and positions in the receiving or dealing rack of cards identified by the card reader can be stored in memory in the controller.
