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.

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

Historically, this involved utilizing invisible ink readable only with special contact lenses, or using a fingernail to create a tiny, microscopic dent in the cardboard.

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

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.

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.
