Scam #6: The Chip Flick Replacement
How it works
A highly skilled mechanic sits at the bottom of the roulette table (the position closest to the columns/dozens area). When a winning number hits in the columns or dozens, the cheater uses a lightning-fast flick of the thumb to knock out the bottom low-value chip from a small stack of $15-$20 on the winning column/dozen. Simultaneously, a high-value chip ($100) is flicked across the apron to replace the displaced chip. The original low-value chip is flicked into the “salad” — the pile of losing chips being swept away — where it disappears among the debris. When the dealer comes to pay the column, the high-value chip is now on the bottom, resulting in a payout many times larger than the original bet warranted.

On the record
This technique is rarely seen in the wild due to the extreme dexterity required, but it has been documented on surveillance footage and is taught as a classic example in casino security training programs.
Published as a detection reference for surveillance, compliance and gaming-operations professionals. Thresholds and tuning are set by the property. Nothing here is instruction — the method is described so it can be recognised.
