Concept by Wayne Rogers with special thanks to Luis de Matos. Check out Luis' DVD "The Magic Square".
This is a professional tool for mentalist and magicians performing the Magic Square.
It can be presented to showcase apparent mathematical prowess, or presented as a mentalism effect.
Members of the audience call out numbers at random. Unbelievably, from these the performer is able to construct a perfect magic square. All the columns, rows, diagonals and corners add up to the same number. Not only that but this number was chosen by a spectator just a few moments earlier. No formulas. No memory work. An incredible mind boggling routine for the professional worker.
