Blackstone's Card Trick Without Cards
From Wikipedia, the free encyclopedia
Blackstone's Card Trick Without Cards is a magic trick. As the trick requires only that a card is thought of, it does not require the use of a deck of cards.
A spectator is instructed to think of any card (other than the joker). The magician then gives the following instructions:
- Take the card's face value (with aces counting as 1 and royal cards counting as 11, 12 and 13 respectively)
- Double it.
- Add 3.
- Multiply by 5.
- If the card the spectator is thinking of is a spade, subtract 1.
- If the card the spectator is thinking of is a heart, subtract 2.
- If the card the spectator is thinking of is a club, subtract 3.
- If the card the spectator is thinking of is a diamond, subtract 4.
The spectator then tells the magician the number the spectator is now thinking of. The magician then names the card.
