The "Twenty-one Card Trick", a classic of card magic revisited... without any physical cards!

The magician shows some pieces of cardboard with pictures on each side.

The first one shows cards scattered in every direction, as if they have been thrown on the floor.
The cards are face up and face down.

A spectator thinks of one of the cards he sees.

The next picture shows three columns of seven cards each, arranged as in the "Twenty-one Card Trick" trick.
The spectator goes through the three columns one by one, each time saying whether or not he sees a card of the same value as his own.

On the next one, all the cards are face up, except for one, which is face down the spectator can't see his card: it's the one that's been turned over!

Then, without asking any questions, the magician guesses the name of the card being thought of!

The picture is then turned over; all the cards are now face down, except one... which is the card thought of by the spectator!

The picture is then turned over again: all the cards are now identical: they are all duplicates of the card that was actually thought of!
