Post-Play Bet Manipulation (Complicit Dealer)
How it works
Normally, post-play (placing or changing a bet after the outcome is known) is a player cheating technique that dealers and floor personnel are trained to prevent. However, when a dealer is complicit, post-play becomes far more effective. The dealer allows an accomplice to add chips to a winning bet (capping), remove chips from a losing bet (pinching), or place entirely new bets after the outcome is determined. The dealer then processes the modified bet as if it had been there all along. In craps, this can involve paying “called bets” that were never actually on the layout - the dealer pretends the bet was there all along. In roulette, the dealer can look away while an accomplice places a late bet on a winning number.

On the record
The Bellagio craps case (2014) involved two dealers allowing friends to place fake bets and paying them regardless of outcome, resulting in over $1 million in losses. One accomplice won $700,000, another over $800,000. The scam operated for nearly two years before a fellow dealer became suspicious.
