The 21 card trick doesn’t require any kind of sleight of hand, so it’s the perfect trick for beginners to learn. The trick relies on math to work, and it practically performs itself. As the magician, you’ll have your audience volunteer pick any card from a small deck of 21 cards. Through a process of laying out the cards in columns, you’ll be able to maneuver their card into the 11th position in the deck, so you can easily reveal their card. If you want a more surprising ending, learn how to make the card-reveal a little trickier.
Things You Should Know
- Using any 21 cards from a deck, have someone pick a card then shuffle it back into the mix before laying out all the cards, 3 across and 7 down.
- Ask your volunteer where their card is and place the column with their card between 2 others; then, lay out the cards again and repeat the process.
- Make the trick more mysterious by delaying the reveal or asking viewers to spell “mystery card” as you lay out the deck.
Steps
-
Take any 21 cards out of a 52-card deck. It can be any 21 cards. What matters is the number of cards, not the suit or color. You can either do it ahead of time or in right in front of your audience members. [1] X Research source
Double check that you have the right number of cards before you begin .
-
Have someone pick a card and then shuffle it back in. Fan the cards out upside down, and have someone select a random card from the pile. Make sure they memorize what the card is, and show it to whoever else is in the audience. Then, have them place the card anywhere and the pile, and shuffle the deck. [2] X Research source- You can even have a volunteer shuffle the deck, so your audience knows you aren’t performing sleight of hand as you shuffle.

Lay out the cards 3 across and 7 down. Start with the top of each column by laying out 3 cards in a horizontal row. Then, lay down the next row, and continue until each of the 3 columns has 7 cards in it. [3] X Research source
- Make sure each column has 7 cards or else the trick won't work!
-
Ask the volunteer which column their card is in. You don’t need to ask this question in a fancy way. Just ask, “Could you point to the column your card is in?” If they lie to you, the trick won’t work, so make sure to emphasize to the volunteer that they need to be truthful about their card's whereabouts.
- If you’re worried your viewer won’t be honest, say, "Be honest now, or the trick won't work!"
-
Sandwich the column with their card between the other two columns. Push together each column into a pile, and then stack the pile with their card in it between the other two piles. Put the deck back together quickly and subtly, so that your viewer doesn’t notice that you are putting the columns back together in any particular order. [4] X Research source
- For example, if the 2nd pile contained their card, you would need to put it in between the 1st and 3rd columns.
-
Lay out the cards again and repeat the process. Arrange the cards in 3 columns of 7. Then, ask the volunteer which column their card is in, and sandwich that column in the middle of the other two columns. [5] X Research source
- Don’t shuffle in between laying out the cards or you’ll mess up the trick.
-
Do the same thing one more time. Lay down the cards in 3 columns that have 7 cards each, then have the volunteer point to whichever column their card is in. Pick up the columns as you did before, sandwiching the pile the volunteer chose in between the other two.
- When the volunteer points to the column with their card in it, their card will be the 4th card down in that column. This is because of how you’ve been moving their column to the middle each time.
-
Reveal that the 11th card in the deck is the volunteer's card. Count out 11 cards and stop at the 11th card. Then, point to that card and announce that it's the volunteer's card. The volunteer will be amazed that you were able to find their card. [6] X Research source .
- Each time you asked which column the volunteer's card was in, you were narrowing down the potential range where their card could be.

-
Perform the basic trick but don’t reveal the volunteer's card yet. Do everything exactly as you would for the normal trick, including laying out and rearranging the cards 3 times. Then, instead of counting out 11 cards and announcing the volunteer's card, make the reveal take longer to build up the suspense and mystery.
-
Ask your audience to spell out “mystery card” as you put down cards. For each letter that they call out, place another card face down on the table. Since “mystery card” contains 11 letters, the card you put down on the "d" will be their card. Enjoy their amazed reactions!
- You can also do this with a phrase that's 10 letters long, like “your card is,” and then flip over their card after they finish spelling it.
-
Deal the cards into 7 face-up piles for another alternative ending. The volunteer's card will be the 11th card you lay down. Ask the volunteer to pick 4 piles. If one of those piles has their card in it, remove the 3 piles they didn't pick. If their card isn't in one of those 4 piles, remove the piles they did pick. Continue asking the volunteer to choose piles and removing the piles that their card isn't in until you're left with 1 pile of 3 cards. Finally, spread out the 3 remaining cards, and announce which one is the volunteer's. [7] X Research source
- Try running your hand over the 3 cards and closing your eyes to pretend you're sensing which card is theirs.

QuestionIs there an easier way to do this?Community AnswerI'm afraid there is no "easy" way. This is one of the easiest card tricks, requiring no sleight of hand at all. To simplify the steps, remember deal by rows, have contestant choose a column, repeat 3x, and in the final selected column, the fourth card is theirs.

QuestionWhat is the mathematical explanation for the trick?Joe LamondCommunity AnswerWhen you pick up the cards the first time it puts the volunteer’s card in the middle 7 of the pack. Then the cards are dealt again, and those 7 are split up further with 2 in the first pile, 3 in the middle, and 2 in the last pile. That narrows it down to 2 or 3 cards. The last deal splits those 2/3 into different piles, and by picking up the cards correctly you have put the volunteer’s card into the middle of the middle of the middle of the pack.

Article Summary

A 21-card trick is a classic magic trick in which you have an audience member pick a card, then move it to the eleventh position in the deck so you can find and reveal it. Start by pulling any 21 cards out of a standard 52-card deck. Next, fan out the cards face-down and ask someone to pick any card. Ask them to remember what the card is and show it to the audience, but not to you. After they’ve done that, have them return the card to your hand, then shuffle the cards. You can also ask the audience member to shuffle them for you. Once the cards are shuffled, lay them out in 3 columns of 7 cards each, and instruct the audience member to point to the column their card is in. Push the columns back into piles, then stack the pile containing their card between the other 2 piles. Repeat this process 2 more times. The third time you lay out the columns, the audience member’s card will be fourth one down in the third column. Stack the cards once more, with the third column in the middle. Finish the trick by counting out the stacked cards until your reach the eleventh one in the deck, then reveal it to the audience and announce that you’ve found the card.
