Ricky Jay is a sleight-of-hand artist and an acknowledged authority on the art of the con. In an NPR interview, Jay related that when David Mamet needed a short-change scam to be explained in "House of Games", he asked Jay for details of an authentic short-change hustle. However, Jay did not want to betray the confidence of the hustlers he knew who still used various short-change cons for their "livelihood". The envelope switch you see in the final film is an original switch invented by Ricky Jay specially for the film. Later, it was reported that an amateur thief had been caught attempting to use the switch as he had learned it from the film.
