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.

Past Posting: The Art of the Late Bet

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

The Complex Scam of 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.

A more sophisticated, highly controversial method popularized by poker legend Phil Ivey is known as "edge sorting."

Dice Sliding at the Craps Table

The craps table is extremely difficult to cheat due to the massive size of the table, the required wall-bounce, and the presence of four highly trained dealers.

This mathematically alters the probability of hitting a 7, giving the cheater a massive, incredibly illegal advantage over the house.

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