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.

Understanding exactly how these professional thieves operate not only satisfies a morbid curiosity but also protects honest players from becoming collateral damage at a compromised table.
How Cheaters Manipulate Casino Chips
The most common and arguably the most difficult-to-detect method of table game cheating is a sleight-of-hand maneuver known universally as "past posting."

This scam requires absolute, flawless timing, massive distraction, and the steady, lightning-fast hands of a professional close-up magician.

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."

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.
