OK, would someone please explain to me how this works?

It guesses right every time. What is the trick?

Here's a hint. Don't just look at the COLOR of the cards before and after, but keep track of the SUITS of the cards before and after.

that's ****ed up! How the hell does it do that?

Your card isn't there because none of the original cards are there

Sorry to spoil the illusion, but NONE of the cards in the first batch are in the second batch. That's how.

OK, got it. I was only paying attention to my card, not the others. I see none of them are there.

Cool trick though.

It's a trick. The cards which come up after you choose...none of them are from the ones you choose...they are all different. So it doesn't guess...any card you choose wont be there. They just look similar.

Scam artists use this trick too

It takes away all of the cards and inserts other ones that look similar so you only notice the one you picked.
