Place 3 additional cards facedown on top of your 4 Jacks. It does not matter what cards these are, as the faces of the cards will never be seen. These will be your secret hidden cards that will make your magic trick work. When you show your audience the 4 Jacks, you will hide these 3 secret cards behind the Jacks. [1] X Research source

The 4 Jacks are robbers and the deck of cards is the bank they’re robbing. As the trick unfolds, you will move the robbers (Jacks) throughout the bank (deck of cards). The magic of the trick is that all 4 robbers will escape to the roof of the bank (top of the deck) in time to get away. The cops are a part of the story of the card trick, and actually have nothing to do with the cards. As long as your story still makes sense with the trick, you can alter this story or add any details that you’d like.

Get your audience to trust you. You’ll be a more believable magician if you’re audience trusts you, so win them over! Do this by smiling, making good eye contact, and treating your audience with respect. [3] X Research source

Begin your Cops and Robbers story by explaining that the 4 Jacks are 4 robbers who have come to rob the bank.

Continue your story. Explain that the 4 robbers are looking for the safe inside of the bank, and that they must split up to find it.

Your audience thinks the cards you just returned to the deck were the Jacks you showed them at the start.

You don’t have to tap the deck. Instead, you can say a magic word or do a special hand movement. The point is to make it seem like you’re doing something magical with your deck of cards.
