Collusion (Player-to-Player / Player-to-Dealer)
How it works
A conspiracy between two or more parties to cheat the casino or other players. Can involve players working together against the house, or players bribing dealers for inside information or manipulations. Signal-based collusion uses coded gestures, phrases, or positioning to communicate hole card information or betting intentions. Dealer-assisted collusion involves bribery for false shuffles, hole card flashing, or intentional payout errors. In blackjack, a dealer might subtly signal whether their hole card is high or low.
On the record
The Tran Organization bribed card dealers and supervisors to false-shuffle. The Justice Department said defendants admitted targeting approximately 29 casinos in the United States and Canada.
