Cheating in casinos refers to actions by the player or the house which are prohibited by regional gambling control authorities.
In Nevada, for a player to cheat in a casino is a felony under state law.
In almost all jurisdictions, casinos are permitted to ban from their premises customers they believe are using advantage play, regardless of whether they are in fact doing so and even though it is not cheating, though this practice of barring law-abiding citizens from public places is subject to judicial review.
So far, courts in New Jersey and North Las Vegas, Nevada have found the practice of barring law-abiding citizens to be illegal.
Some casinos use facial recognition software to detect known cheats and criminals.
