How to Spot Cheaters at the Casino

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.

Understanding the "Past Posting" Scam

If they win a hand of blackjack, their original $10 bet is magically transformed into a $100 bet right before the dealer pays them out.

Often, a confederate (an accomplice) will intentionally spill a drink or loudly argue with a waitress at the exact moment the cheater makes the move.

• Past posting involves adding chips to a bet after the player already knows they have won
• It is also called "late betting" and is most common on the crowded, chaotic roulette tables
• Cheaters use palm-palming techniques to hide the extra chips in their hands

How Players Manipulate the Deck

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.

Edge sorting relies on finding tiny, microscopic manufacturing defects in the geometric patterns printed on the absolute back edge of the casino's playing cards.

How Cheaters Manipulate the Dice

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.

This mathematically alters the probability of hitting a 7, giving the cheater a massive, incredibly illegal advantage over the house.

The glamorous era of casino cheating has largely been eradicated by incredibly advanced facial recognition, RFID-chipped betting tokens, and relentless surveillance.
