Casting Out 10s

Amaze your friends with your Rain Man-esque card counting skills!

Have you always wanted crazy Rain Man math skills, without the annoying People's Court fetishization that comes with it? This week, we teach you a card trick that will make your friends think that you are a card-counting genius! Definitely a genius.

Shuffle the deck, and deal out two cards face down, one for you and one for your mark. Tell them to open their mind as you quickly run through the remaining cards. Let them try to guess your card. Look at your card, and give them one more quick peek at the other cards. In just those two quick peeks, you can easily determine what their card must be. Alcohol-induced autism? Nope, it's just simple arithmetic. Watch the show to find out the solution!
