Some commonly used techniques for cheating in illegal gambling include card marking, sleight of hand, collusion with other players, and using electronic devices to manipulate the outcome of games. Card marking involves marking the cards in a way that is invisible to others but can be identified by the cheater. Sleight of hand involves skillfully manipulating cards or chips to gain an advantage. Collusion with other players involves working together with others to rig the game in your favor. Using electronic devices such as hidden cameras or devices that can control the outcome of games can also be effective in cheating in illegal gambling.
