Response: The Final 3 - Amazing Math Card Trick

Additional: I've been trying to simplify the setup so how about this. Ask two volunteers to pick a card, then make three piles of fifteen. Ask the volunteers to choose one of the three piles by placing their card on top of it. The other pile is for you and your chosen card is the card on top of that, show it off. Now collect the deck with your chosen pile on the bottom, and the remaining five cards on top. This will put the three chosen cards in the correct position for the rest of the trick.

3:33 CUT

[Waitingtoexplode]

I was once told that the greatest hallmark of intelligence is the ability to take any concept and reduce it to an explanation that anyone can understand, this is the definition of an elegant description. Bravo!

@AZNPride2k11 I will explain it. When you put the selected deck in second, it will always be one of the cards 8-14. These will now be one of the middle 3 cards of the 3 decks if you lay them out like you should. When you take the deck with the card in it as the second one again, it can only be one of 3 cards. when you lay these out again, these 3 cards will all be lined up in the same spot of the 3 decks, which is the 4th position. That means it will always be 11th(7+4).

Did you use a stratus deck by Cartamundi?

[tandrewfield]

There are some powers of 2 in this as well: 2, 4, 8, and 16.In the first cut of the reveal you cut the deck in half, or leave only every 2nd card (the even numbers). During the second, you cut that in half, leaving every 4th card, starting with 2(2,6,10, 14, etc.).You cut these in half leaving every 8th card starting with 6(6,14,22, etc.)Finally you leave every 16th card starting with 6, which is 6,22,and 38!16 cards don't go evenly into 52;there is a remainder of 4 - the 4 cards at the end.

[tandrewfield]

Definitely you start with how you want to reveal the cards and then design the trick around it. Algebraically, call the chosen cards A,B,&C. Call the number of cards in the 2 cuts "x" and "y."Your deck before moving the 4 cards to the bottom is stacked top to bottom like this: 9 cards, Card A (position 10), 15-x cards, x cards, Card B (position 26), 15-y cards, y cards, Card C (position 42), and 10 cards. Note that 15-x+x = 15 which is how there are 15 cards in between A-B and B-C.

@SmoothCriminalzTv Did you take 4 cards off the top of the deck and place them on the bottom?

[SmoothCriminalzTv]

Every time I try,none of the 3 cards I chosed are the final 3.

Why?
