one, all a magician needs to do is order the cards so that each card is three values greater than the previous card, and so that the suits cycle consistently. For example: , , , , , , etc. The simplest way to use a Si Stebbins Stack is to let the spectator cut and replace the cards and look at the top card. They then replace the card on top and the magician takes the deck and peeks at the bottom card. Now, using the sequence of the Si Stebbins Stack, the magician adds three to the card value they peeked, and cycles one suit. Now they can continue the trick as usual. The Si Stebbins Stack also allows for more complex mind reading techniques using additional mathematical principles. See also Card marking One-way deck References Card tricks
