Scam #14: Floor Supervisor Credit/Fill Manipulation

How it works

Floor supervisors are responsible for authorizing fills (chips sent from the cage to the table) and credits (excess chips returned from the table to the cage). A corrupt supervisor can manipulate these transactions to steal chips or facilitate collusion. Methods include: authorizing unnecessary fills and diverting chips; falsifying credit slips to overstate chips returned (pocketing the difference); creating phantom fill/credit transactions; manipulating paperwork to cover chip shortages caused by collusion; and co-signing fraudulent documents. In the historical Stardust skimming case, executives created false fill slips to account for cash that was being skimmed from the casino.

On the record

The Stardust skimming operation involved falsifying fill slips to cover cash removed from the casino. This method has been used in various forms since the earliest days of casino gaming.
