One of the cards has a blue dot, and the other two cards both have a red dot.
The game? Keep track of the blue card. Guess right, you win! Guess wrong, you lose. Simple, right?
But each time he’s sure about where the blue dot is, he’s wrong.
Top card? Wrong!
Bottom card? Still Wrong!
Center card? Once more, Wrong!
He accuses the hustler of hiding the blue card. Wrong Again!
Desperate, his losses piling up, he takes one last bet. The hustler flips two cards: one red, one blue, and asks the magician to guess the third card’s colour.
Red, right? Wrong!
Then it MUST be blue? Wrong!
