A series of 6 cards would be shown to a person after they mentally selected a number from 1 to 63. For each card they see, all they have to do is let you know if their number can be found on the card. At the end of the sixth card being shown, you let them know what number they were thinking of. 

Thank you for taking time to look at eyeCard !
