Card magic tricks have always been fascinating for people of all ages. From simple card tricks to complex ones, everyone enjoys the thrill of seeing a card being picked, shuffled, and magically appearing in unexpected places. One of the most popular card magic tricks is the 21 card trick. It involves some simple math, but when performed correctly, it can leave the audience amazed and wondering how it was done.

What is the 21 Card Trick?

21 Card Trick

The 21 card trick involves 21 cards that are laid out in three rows of seven cards each. The performer asks the audience to pick a card and remember it. The card is then shuffled back into the deck. The performer then proceeds to lay out the cards in three rows, face down. The audience is asked to point to the row that contains their card. The performer repeats this process two more times. After the third time, the performer is able to correctly guess the audience member's card.

How Does it Work?

Math Equation

The secret to the 21 card trick is simple math. The performer needs to remember the bottom card of the row that the audience member points to. From there, it's a matter of adding or subtracting the value of the cards in that row to get to the chosen card. For example, if the chosen card is the five of hearts, and it's in the middle row, the performer needs to remember the bottom card of the middle row. Let's say it's the queen of clubs, which has a value of 12. To get to the five of hearts, the performer needs to subtract five from 12, which gives us seven. The seventh card in the middle row is the chosen card.

Of course, this is easier said than done, and the performer needs to be quick with mental math to make the trick look seamless.
