    A simple magic square game demonstrating nonclassical correlations was introduced by P.K. Aravind [3] based on a series of papers by N. David Mermin [4] [5] and Asher Peres [6] and Adán Cabello [7] [8] that developed simplifying demonstrations of Bell's theorem. The game has been reformulated to demonstrate quantum pseudo-telepathy.
