Magic Number Mystery

The magician shows 6 cards to the spectator. Each of the cards has about 30 different numbers on it ranging from 1 to 63.  No two cards are alike.
The audience member simply thinks of ANY number between 1 and 63 and indicates which of the cards their number appears on.

INSTANTLY , the magician can name the chosen number.

This is an old trick - but Trap Door Magic® has added a secret special twist to make it even more up-to-date and amazing.  The magician doesn't even need to see the faces of the cards and the trick still works like magic!  (This means you can fool those who may already know the old version secret because this new method is TWICE as amazing.)

No special skill is required... it is based on simple math. The cards are small - so it makes a great pocket trick.
