The Ouija, also known as a Ouija board, spirit board, talking board, or witch board, is a flat board marked with the letters of the Latin alphabet, the numbers 0–9, the words "yes", "no", and occasionally "hello" and "goodbye", along with various symbols and graphics. It uses a planchette as a movable indicator to spell out messages during a séance. Participants place their fingers on the planchette, and it is moved about the board to spell out words. The name "Ouija" is a trademark of Hasbro, but is often used generically to refer to any talking board.
