Exclusive Digital Magic Products for Magicians

The Triskadequadra Principle marks a substantive step forward in the evolution of card magic. John Hostler has isolated two very special properties inherent in a riffle-shuffled deck ?C properties buried in the mathematics underlying tools such as the Gilbreath Principle. A must-have for serious pasteboard scholars and principle geeks, this ebook also provides a generous selection of real-world applications:

• Equilibrium ?C Cards are slowly dropped to the table until a spectator senses equilibrium. These cards are found to comprise an intriguing (and previously predicted!) mix of the four suits.
• Rogue Heart ?C A card selected in tension-building fashion “optimizes” a secret poker hand held from the start by a spectator.
• Bar Bits ?C Two clever pub swindles designed to wet your whistle on any given Saturday night. For entertainment purposes only.
• Suitelepathy ?C A telepathic connection allows the performer to divine the colors and suits of a freely selected packet of cards.
• The TDQ Deck ?C A combination force/pump deck that can be spectator-shuffled and displayed face-up.
