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.

Understanding the "Past Posting" Scam

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.

How Players Manipulate the Deck

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.


By convincing the dealer to rotate specific high-value cards 180 degrees, the player can easily identify them before they are dealt, completely destroying the house edge.

The Mechanics of a Craps Scam

However, highly skilled mechanics attempt a scam known as "dice sliding," which completely removes the random tumble of the dice.


To combat this, casinos mandate that both dice must physically bounce off the chaotic, rubber pyramid "alligator" siding at the far end of the table.
