Since the very first casino opened its doors, an endless war has raged between the operators trying to protect their money and the criminals trying to steal it.
Understanding exactly how these professional thieves operate not only satisfies a morbid curiosity but also protects honest players from becoming collateral damage at a compromised table.
How Cheaters Manipulate Casino Chips
Past posting occurs when a cheater incredibly quickly and silently adds additional chips to their winning bet exactly a split second after the winning outcome is determined.
This scam requires absolute, flawless timing, massive distraction, and the steady, lightning-fast hands of a professional close-up magician.
- Modern roulette tables feature advanced sensors to detect any chip movement after the ball drops
- Dealers are trained to intensely stare at the chips immediately after announcing the winning number
- Past posting is a severe felony offense, not a simple misunderstanding of the rules
Card Marking and Edge Sorting
Cheaters attempt to destroy this mystery by physically marking the high-value cards (like Aces and Faces) so they can be identified from the back.
A more sophisticated, highly controversial method popularized by poker legend Phil Ivey is known as "edge sorting."
Dice Sliding at the Craps Table
Instead of throwing the dice into the air, the cheater expertly slides one of the dice completely flat across the felt, preventing it from ever tumbling.
By keeping the desired number facing upward during the entire slide, they only have to worry about the random outcome of the second tumbling die.
| Cheater Action | Dealer Counter-Measure |
|---|---|
| Pinching (Stealing back a lost bet) | Clearing losing bets before paying winners |
| Marking Cards with fingernails | Replacing the entire shoe of cards frequently |
Attempting to cheat a modern casino is an incredibly foolish endeavor that almost universally ends in severe felony charges and prison time.
