Some of the methods used to cheat at casino games are complex, requiring multiple people or some insider knowledge to pull off. On the other hand, past posting isn’t sophisticated at all, requiring only some slight of hand from the gambler who wants to cheat the casino.
Past posting refers to any bets made after the croupier has already called for no more bets to be taken. The name actually comes from the world of horse racing, where scams that involved betting on races that have already begun (or even better, already ended) were once fairly common. In roulette, the idea would be to get your bet onto the table only after you’ve already seen where the ball has landed.
This isn’t an easy feat to pull off, especially given how much attention casino staff pays to what’s going on at the table. Distracting dealers isn’t easy, and if there are multiple personnel at the table, the cheater’s job is made exponentially harder. Add in the presence of security cameras, and this isn’t a cheating method that will work for very long.
One twist to this scam is called pinching. This involves taking a bet that has already been placed and removing chips if that bet should lose. This can give a cheater a huge advantage, as they’ll reduce the size of their losses while maximizing how much they can win when they don’t “pinch” a bet. Of course, the cameras and casino staff are once against an issue, which makes pinching much less common in the modern casino world.
