This effect is related to an old trick from one to sixty-three arranged on six cards in a seemingly random order, but it takes the old effect to a new level. Both effects rely on binary mathematics to work, but you really don't need to understand why or how. In the number trick, a spectator thinks of the one of the numbers and tells you which cards show the number. You are then required to add up the total of the numbers appearing first upon each to arrive at the mentally chosen number. For many performers, that's no easy feat to do in your head while you are trying to be entertaining and disguise the method at the same time. To perform MISSING THINK you don't even need to know how to add, since no math is involved during the performance! Once you read the secret, you'll be able to perform this effect immediately with no hesitation.
