Poker Collusion via External Communication (Live)

How it works

Players at the same or adjacent tables use hidden mobile phones, earpieces, or messaging apps to share real-time hole card information. One player may text their hole cards to a confederate who advises on optimal play, or two players at the same table may communicate through concealed Bluetooth earpieces. A more sophisticated variant involves a “coach” outside the cardroom providing real-time advice based on a hidden camera feed or direct communication.

On the record

In the 2019 Stones Gambling Hall case, the mechanism alleged by accusers was a phone at the table relaying hole-card information, with a concealed audio device as a second theory. The allegations were never tested at trial: no charges were brought and the civil class action was dismissed in 2020. The value to a monitoring room is the mechanism, not the case — a phone in the lap during a streamed game is a surveillance question whatever the outcome.
