Part II: Table Game Cheating · Roulette Cheating Methods

Scam #4: The Late Stack Drop (a.k.a. Snap Slide)

How it works

A single cheater or team member places a stack of chips onto the layout just as the ball drops into the winning number. The move is lightning-fast and relies on perfect timing. The cheater watches the ball’s final descent and, at the exact moment the dealer’s attention is on the wheel, slides a pre-prepared stack onto the winning number or adjacent area. In a sophisticated variation, the stack has the high-value chips offset at the bottom, so when the dealer notices the late stack and removes it, the offset high-value chips remain behind — creating a “legitimate” winning bet out of thin air. The dealer, seeing only the removal of the late stack, may not notice the hidden chips left behind.

On the record

This technique has evolved significantly with surveillance technology. Modern cheaters rarely attempt it more than once at the same table, preferring “hit and run” tactics across multiple properties.
