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.

The casino's "Eye in the Sky" catches most of them eventually, but recognizing the signs of a scam unfolding right next to you is a fascinating skill.

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.

While the dealer's eyes are momentarily distracted by the sudden commotion, the extra high-denomination chips are seamlessly slid onto the winning betting circle.

• The scam almost always involves a loud, intentional distraction created by an accomplice
• Cheaters also use "pinching," which is removing chips from a bet after losing the hand
• If a player is constantly hovering their hands near their chips after the deal, pit bosses become highly suspicious

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.

Dice Sliding at the Craps Table

However, highly skilled mechanics attempt a scam known as "dice sliding," which completely removes the random tumble of the dice.

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.

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