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.

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.

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

Card Marking and Edge Sorting

In card games like Blackjack and Baccarat, the entire house edge relies entirely on the fact that the next card in the shoe is a complete mystery.

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.

Attempting to cheat a modern casino is an incredibly foolish endeavor that almost universally ends in severe felony charges and prison time.
