Mysterious Mindreader Cards

Want to amaze your friends with your ability to read their mind??  This will do it!  There are 6 wood cards, each laser engraved with 59 or 60 different numbers.  The numbers 1 through 60 are on the cards, with most repeated a number of times.   Simply ask a friend to select a number but not to tell you. Then ask him to look at each card and turn over any that do not contain the number he is thinking of.   Within seconds you will be able to tell him the chosen number!

This is made using hardwood cards and in a box set. Hardwood cards are 2 1/8" square x 1/4 thick. 

Even a child (8+) who can add some simple numbers can do this magic trick!
