The notion of secret codes or signals used by casino staff to communicate or manipulate games is more the stuff of fiction than reality. Casinos operate under strict regulations and surveillance, making it highly unlikely for such practices to occur unnoticed. Staff members are trained to adhere to professional standards and ethical conduct, with rigorous protocols in place to ensure game integrity and security. Any attempt to manipulate games or communicate covertly would be quickly detected and dealt with by casino management and regulatory authorities. While there may be some informal communication methods used by staff for operational purposes, they are not intended for manipulation or dishonesty. Trust and transparency are essential to maintaining the integrity of casino operations.
