This episode is based on a true story. Long before personal computers etc a couple of math scholars actually found a way to predict and beat roulette tables. They were never caught and once they did it donated their computer to a museum.
On the W2-G form that Grissom pulls out of the dead guy's pocket the address states Rampart Casino 221 North Rampart Blvd. That is the actual address of the Rampart Casino in Las Vegas.
