Four kings - Easy Self Working Card trick revealed

Step by step

1. Prepare 20 random cards and four other cards of your preference (four Kings in my case)
2. Let the spectator place four cards anywhere in the pile
3. Spectator can cut the pile as many times he want
4. Start placing cards on the table - let one card facing down, second card turned up, third card facing down and so on thru all cards in the pile
5. Now spectator will decide if cards should be turned or placed on the table as they are (this time we will turn cards in pairs)
6. Finally we will be manipulating with four cards and spectator will decide if cards should be turned or placed on the table as they are
7. Square up the deck and make two piles
8. Look in which pile you will see spectators cards
9. Take the other pile, turn it over and place on the pile with spectators cards
10. Spread the cards and show the result - all four cards are now facing up again!
