1 How to Spot Cheaters at the Casino
Damian Baltzell edited this page 4 weeks ago


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.

Cheating is no longer about complex card counting (which is technically legal); it is about physically manipulating the cards, the dice, or the chips after the outcome is known.
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.

This scam requires absolute, flawless timing, massive distraction, and the steady, lightning-fast hands of a professional close-up magician.
Modern roulette tables feature advanced sensors to detect any chip movement after the ball dropsDealers are trained to intensely stare at the chips immediately after announcing the winning numberPast 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.

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.
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.

Attempting to cheat a modern casino is an incredibly foolish endeavor that almost universally ends in severe felony charges and prison time.
