The Riffle Force is an intricate sleight of hand technique used in card magic to control the selection of a card by a spectator. This method involves deft manipulation of the deck, executed with such subtlety that it appears random to the untrained eye. The performer, through a series of seemingly nonchalant shuffles and cuts, ensures that a preselected card is chosen. In its purest form, the Riffle Force blurs the line between skill and artistry. Despite being one of many forces within the conjuror’s repertoire, it stands out due to its high success rate and versatility in both close-up and stage performances.
