Scam #24: Dealer-Assisted No-Call No-Pay

How it works

In this scam, the dishonest dealer selectively enforces — or fails to enforce — game rules to benefit a confederate. For example, the dealer may fail to call “no more bets” and allow the accomplice to continue placing chips after the ball has dropped. Or the dealer may “accidentally” pay a bet that was clearly placed too late, claiming they didn’t see it in time. The dealer may also deliberately miscall the winning number, paying bets on a neighboring number where the confederate has chips. In another variation, the dealer fails to collect losing bets from the confederate, allowing them to play the same chips again on the next spin. These abuses rely on the dealer’s authority over the game and the difficulty of proving intent.

On the record

This type of collusion is particularly dangerous because it can be masked as simple dealer incompetence. Distinguishing between a poorly trained dealer and a deliberately dishonest one requires careful pattern analysis over time.
