This set of 8 cards plus header card will allow you to predict any number chosen between 1 and 61. Its a slight twist on the standard set but still uses the same easy kind of math to determine the selected number.
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!
