Shell game

Confidence trick

The shell game (also known as thimblerig, three shells and a pea, the old army game) is a public gambling game that challenges players to follow the movement of a marker hidden under one of several covers (shells). In practice, the game is almost always run as a confidence trick that uses sleight of hand to transfer the marker between covers. In confidence trick slang, this swindle is referred to as a short-con because it is quick and easy to pull off.
