1. A method of shuffling cards, comprising: providing a set of cards to be shuffled on a support surface such that an edge of each card is supported by the support surface, the support surface having a slot therethrough sized to enable only one card to drop through the slot at a time; randomly positioning a support structure such that only a first card of the set of cards drops through the slot and stops on a card stop beneath the support surface such that the first card partially remains in the slot, wherein a trailing edge of the first card is positioned such that other cards of the set of cards can slide over the slot but no additional card can enter the slot, wherein the support structure is positionable on first and second sides of the set of cards to be shuffled; randomly positioning the support structure to move the set of cards laterally across the support surface and to align a randomly selected second card with the slot; and removing the first card from the card stop to allow the second card to drop through the slot and contact the card stop beneath the support surface such that the second card partially remains in the slot, wherein a trailing edge of the second card is positioned such that other cards of the set of cards can slide over the slot but no additional card can enter the slot.
