The 21 card trick is a strong magic trick that is fun and easy to do. It is perfect for when someone hands you a deck of cards and tells you to blow their mind.
Here you will learn, step by step, how to do the 21 card trick. I’ve included four incredible ways to reveal the thought of card, which takes this trick to the next level.
What is the 21 Card Trick?
Your spectator thinks of a card, you tell them the card they are thinking of. The 21 card trick does not involve any skill or sleight of hand and is perfect for anyone new to card magic.
It is a baffling self-working card trick and relies entirely on a math principle.
You only need 21 cards, it doesn’t matter what they are. Put the rest of the deck aside.
21 Card Trick Explained
Hold the cards in your hand face down.

- Deal cards face up, left to right, into rows of 3, making three columns of 7 cards each.
- Tell your spectator to think of one of the cards.
- Ask them which of the 3 columns their card is in.
- Gather the columns into a pile, sandwiching the column with their card in the middle. Turn the whole packet face down.
- Repeat steps 1-4 two more times (excluding step 2).
- Deal 10 cards face down and flip over the 11th card, it will be their card.

21 Card Trick Endings
1. Dealing to Their Card
Slowly deal the cards face down into a pile. Count silently to yourself. Deal 10 cards, the next will be their card. Pause. Slowly turn over the 11th card mysteriously revealing their card.

2. Spelling to Their Card
Hand your spectator the cards. Tell them to deal cards one at a time, face down, into a pile, spelling out the magic word ABRACADABRA, one card per letter.
Have your spectator turn over the card that falls on the last A of abracadabrA. It will be their card.
Since abracadabra is spelled with 11 letters, this is a perfect ending. You can use other words or names that have 11 letters, for example MINDBLOWING.

3. Reading Their Mind
For the third and final time you lay out the cards, their card will be exactly in the middle of the pile. When they point to their pile, remember the card 4th from the top or bottom.
Gather the cards and place them aside, you no longer need them. Act as if you are reading their mind, and reveal their card. Play it up a little so it adds to the mystery.
“You are thinking of a red card, a heart…the 10 of Hearts.”

4. The Card Appears in Their Hand
This is a really cool way to reveal their card and can be used in many card tricks. You will get an amazing reaction.
Deal 7 cards onto the table. Take the next four face down cards and place the rest of the deck on the table. You are now holding the 8th, 9th, 10th, and 11th card in a face down pile.
Their card will be on bottom. Ask them to hold out their hand in a loose fist, with their curled fingers toward you. Mime the actions to show them exactly what you want them to do.

Place the 4 card pile between their 1st and 2nd fingers at the knuckle. Make sure they are not holding the cards too tightly.
You are going to firmly, yet gently, in a downward motion, smack the cards out of their hand. Do this over a table. Because of friction, the bottom card will be the only card they are left holding.
This revelation is extremely impressive and always gets a gasp.
21 Card Trick Tips
- Deal the cards quickly, dealing is “dead time.”
- Layout the cards before you start the trick so your spectator sits through one less dealing.
- Make sure to put their pile in the middle.
21 Card Magic Trick Variations
Spectator Shuffles
Instead of laying out the cards before having a card thought of, hand them the 21 cards at the beginning, have them look through, think of one, and then shuffle. Take the cards back and do the layout procedure 3 times.
I like that your spectator gets to shuffle, yet I don’t like that you have to deal the cards out 3 times. Since the dealing procedure is the worst part of the trick, I prefer to do the first deal before they think of a card, before the trick even starts.
27 Card Trick
When the same method is applied to 3 piles of 9 cards each, it is called the 27 card trick. It is identical in principle and procedure. Their selection will end up being the 14th card down in the packet.
Personally I would stick with 21 cards. It is less dealing and quicker. In the end it is the same exact trick.
