Part II: Table Game Cheating · Dice & Craps Cheating Methods

Thumb Palm Switch / Casino Thumb Palm Switch

How it works

A discreet method for switching a pair of dice using a thumb palm position. The cheat holds the gaffed dice concealed in the thumb palm (pressed against the base of the thumb) while reaching for the legitimate dice. When picking up the legitimate dice, the gaffed dice are released and the legitimate dice are simultaneously palmed away. This switch is particularly effective in casino environments because it can be performed while appearing to simply reach for the dice normally. The motion is small and natural-looking.
