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.
Cheating is no longer about complex card counting (which is technically legal); it is about physically manipulating the cards, the dice, or the chips after the outcome is known.

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.
- 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
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.
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
However, highly skilled mechanics attempt a scam known as "dice sliding," which completely removes the random tumble of the dice.
This mathematically alters the probability of hitting a 7, giving the cheater a massive, incredibly illegal advantage over the house.
| Cheating Method | Target Game | How it Works |
|---|---|---|
| Past Posting | Roulette / Blackjack | Adding chips to a winning bet late |
| Edge Sorting | Baccarat | Exploiting asymmetrical card patterns |
The glamorous era of casino cheating has largely been eradicated by incredibly advanced facial recognition, RFID-chipped betting tokens, and relentless surveillance.
