You place five playing cards on the table. You then show the Spectator a poker chip that has a prediction on one side. You ask the Spectator to mix up the five cards so they are not in any particular order. You ask the Spectator to place the poker chip onto any one of the five playing cards. When you turn over the poker chip, and the playing card, the prediction on the back of the poker chip matches the playing card chosen by the Spectator - that's 'Gambit'.
