Card Trick Mechanics and Math Concepts

This video tutorial teaches a card trick where the performer gives a spectator nine cards to shuffle and remember the top card. The performer then shuffles the rest of the deck and places cards on top of the spectator's pile. The performer creates four piles, counting down from 10, and stops when a card matches the number. The numbers where the performer stops are added together, and the total is used to count through the deck to reveal the spectator's card, the Queen of Spades. The trick relies on simple math and a full deck of 52 cards.
