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.
Understanding the "Past Posting" Scam
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.
Past posting involves adding chips to a bet after the player already knows they have wonIt is also called "late betting" and is most common on the crowded, chaotic roulette tablesCheaters use palm-palming techniques to hide the extra chips in their hands The Complex Scam of Edge Sorting
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.

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.
Dice Sliding at the Craps Table
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.
