1. The Four Robbers
This is a fairly easy one, and basically involves you taking the 4 Jacks (4 robbers), 'putting' them in random places, but, by the end, they are all back at the top of the deck.
What you have to do is get the 4 Jacks together and place another 3 random cards on top of them. Fan the 4 Jacks out and show them to the audience (make sure you don't show the 3 cards). Now start your story by saying "Four robbers decided to rob a house". Taking one of the random cards, say "The first robber got into the house through a cellar window", and put it back near the bottom of the deck, without showing the face of the card. Make up some more tales about 2 other robbers, and finally say "The last robber decided to stay on the roof", and show this card to them, which will be a Jack, instead of a random card. Then say, "The police came to the house and, what do you know, they were all on the roof!", and show them the 4 Jacks!
2. The Four Aces
In this trick, you get another person to divide the deck into 4 equal piles. You then make him take cards from one pile to another in such a way that all the cards seem muddled up, but, in fact, there'll be aces on top of each of the piles.
To do this, you have to put all 4 Aces on top of the deck. Give the deck to your 'trickee' and get him to divide it into 4 piles. Keep an eye on which deck contains the Aces. Then, tell him to move a card from the 'Aces' pile to another pile, and so forth. Make sure you keep an eye on where the aces are going. A way to make this trick easy for you is to memorise a sequence, so that, at the end of it, you have aces on the top of each pile.
3. The Red and the Black
In this trick, you initially write down a 'prediction' and give the paper to the spectator. You then get him to take the pile, and take 2 cards at a time and reveal them. If they both are black, he puts them in one pile, face - up. If they both are red, he puts them in a different pile, again face - up. If it's a red and a black, he puts them in a third pile face - down. After the cards are finished, he counts the number of cards in each of the first 2 piles, and will read your prediction (You will have 2 more black cards than red cards), and find that this is true!
To facilitate this trick, before you give the pile, you remove 2 red cards. Therefore, inevitably, there will be a deficiency in the red cards. You can remove 2 black cards, and reverse your prediction!
