Another great trick by Roddy McGhie. I now own 3 tricks by R.M. ALL involve a card box and a
sharpie. Also own Chop by Craig Petty, which uses a sharpie! I would rate this trick at close to
100% for easy to do & amazing spectators reaction. A real gem of a trick with reference to the
classic coin matrix. I liked the alternate handling of the black dots being on a bicycle card rather
than the solid black card.
