A more low-tech version of a casino scam was the subject of a 1966 Warren Beatty film called Kaleidoscope.

The author said most of the scams in his book come from real life, so it's possible someone did it in the past.

James Swain is the author, the series is his "Tony Valentine" books. Not fantastic writing, but packed full of scams and cons if you enjoy that kind of thing.
