Ask a person to select any three cards from the pack without looking at them and to place the cards face down on the table.

Eventually you are going to ask the person to select a card,which you will pair in both number and colour.

In privacy and before the trick commences you make a mental note of the fourth card from the bottom of the pack at the same time removing the card of the same number and colour from the pack.

Turn the three cards over, which up to now have been face down and say that you wish to make three piles of cards add up to 15 using the three cards showing. This is done by using the number on the card shown (Jack is eleven, Queen twelve and King thirteen) and adding the appropriate number of cards face down to add up to fifteen (i.e. if a six is shown, add nine cards, if a Jack is shown, add four cards, etc.)
