Okay my friend showed me a magic trick and i can't figure out how he did it..
This is what he did:
1. put the SHUFFLED cards into separate piles with different amounts in them. but sometimes if there is a king, he puts it in a separate pile by itself with all of the cards faces facing up. (possible significance)
2. flips the piles so they face down.
3.then has the other person take all the piles except three (the king counts as a pile)
4. then the person flips the top of any two of the 3 remaining decks & he has to guess the other top card.
5. to guess it, he takes the cards that the person took away in step 3 and with them faced downward, he either counts them or something.
