Next, place your other hand face-up under the bottom of the deck, and slowly lift up your thumb that’s gripping the deck to release some of the cards into your bottom hand. Bend your index finger and press it down into the center of the top of the deck. First, grip the short ends of the deck between your thumb and the rest of your fingers. For a more advanced technique, try the riffle shuffle. Repeat several times to fully shuffle the deck.
Press the cards you lifted up back into the deck at a new location to shuffle them. Then, lift up part of the deck, letting the rest of the cards slide down into your hand below. First, grip the short ends of the deck with one of your hands, and place your other hand below the deck. To shuffle a deck of playing cards, try doing the overhand shuffle.
