You can even have a volunteer shuffle the deck, so your audience knows you aren’t performing sleight of hand as you shuffle.

Make sure each column has 7 cards or else the trick won’t work!

If you’re worried your viewer won’t be honest, say, “Be honest now, or the trick won’t work!”

For example, if the 2nd pile contained their card, you would need to put it in between the 1st and 3rd columns.

Don’t shuffle in between laying out the cards or you’ll mess up the trick.

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.

Each time you asked which column the volunteer’s card was in, you were narrowing down the potential range where their card could be.

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.

Try running your hand over the 3 cards and closing your eyes to pretend you’re sensing which card is theirs.
