Paint Poker is an app version of a classic magic trick called “Cardiographic”.
The magician has a spectator think about a card and then open a drawing app and begins to read spectator’s mind then draw the card in the app. He reveals his drawing but that is incorrect.
He then adds a few lines to the drawing and tells the audience that it is a deck of cards and that one is just the top card.
He tells the spectator to concentrate on their card and the chosen card rises from the drawing deck of card!
