Dealer-Signaled Past Posting

CollusionREPORTEDSkill: Intermediate

How it works

In this scam, a dishonest dealer uses subtle signals to inform a confederate player when past-posting opportunities exist. The dealer may deliberately turn their back to the layout for an extended period while “examining” the winning number, use a specific phrase or tone of voice, position the dolly in a certain way, or use hand gestures that appear normal to observers but convey a specific meaning to the accomplice. When the signal is given, the player knows the dealer will not be watching the layout and can safely place a late bet. The dealer then “discovers” the late bet, removes it with an apology, but may accidentally-on-purpose leave a portion of it behind: or the player may have already gained useful information about which number to bet on the next spin.

On the record

Dealer signaling has been a persistent problem throughout casino history. The most insidious aspect is that it can be nearly impossible to prove in court: gestures and phrases can always be explained away as innocent behavior.
