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.

• 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

How Players Manipulate the Deck

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.

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.

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.
