Spades: 7 6 5 4 3 2 ace king queen jack 10 9 8.
Hearts: 10 9 8 7 6 5 4 3 2 ace king queem jack.

Rule 1 Each card has a numerical value, Ace=1, jack=11, queen=12 and king=13.

Rule 2 Each card is THREE numbers apart, Ace, 4, 7, 10, etc.
Rule 3 Every thirteenth card is a card of the same value, but a different suit.

The last trick:Tell the spectator that you can tell them how many cards down the pack their chosen card is and ask them to choose any card, number and suit. Then locate the card with the same suit as the one named by the spectator, which is nearest to the bottom. Subtract the number of the card chosen from the card of the same suit nearest the bottom of the pack. Then multiply the answer by four and then subtract the number of cards that were below the bottom suit card, the result will be how many cards down from the pack you must count to reach the spectator's chosen card. If the chosen card is a higher value than the suit card on or nearest the bottom of the pack, just add 13 and proceed as above.
For example: if the spectator chooses the 9 of diamonds and the card with the same suit nearest the bottom is a 5 of diamonds, you will need to add 13 to the 5 of diamonds, making a total of 18. Now subtract their card, the 9 of diamonds from 18, this leaves the number 9, multiply 9 by 4, which equals 36, then subtract the number 2 (which is the number of cards below the bottom suit card). This totals 34, so the 9 of diamonds is 34 cards down from the top of the pack.
