This is the one card trick I know that amazes people, because it is really not a trick…it just works out mathematically.  But I have never had anyone, math majors included, who could tell me why it works.  So, please, if you figure it out, enlighten me.

Here it is…

Use a deck of 52 cards…no jokers.

Turn the first card face up and start with its numeric value, turning face up the next card and counting up to 13.  For example, say you turn over a 4, the next cards will be counted 5, 6, 7 and so on until you get to 13.

Turn that pile over face down.

Make 2 more piles.  Facecards count as 10.  Aces count as 1.

So now you have 3 piles.  You ask someone to turn over the top card of any 2 piles.

Add the numeric values together.  Let’s say one card is a 4 and the other card is a face card, so 4 plus 10 is 14.   Now add 10 to the sum, so that would be 24.

Count out 24 cards from what’s left in you hand.  The number of cards left in your hand after that will be the numeric value of the top card of the 3rd pile.

Works every time!
