A fortune teller is a form of origami used in children's games. Parts of the fortune teller are labelled with colors or numbers that serve as options for a player to choose from, and on the inside are eight flaps, each concealing a message. The person operating the fortune teller manipulates the device based on the choices made by the player, and finally one of the hidden messages is revealed. These messages may purport to answer questions (hence the name), or they may be activities that the player must perform.
The same shape may also be used as pincers or as a salt cellar. Another common name for it is a cootie catcher; it has many other names.
