The ouija (/ˈwiːdʒə/ WEE-jə, /-dʒi/ jee), also known as a spirit board or talking board, is a flat board marked with the letters of the alphabet, the numbers 0–9, the words "yes", "no", occasionally "hello" and "goodbye", along with various symbols and graphics. It uses a planchette (small heart-shaped piece of wood or plastic) 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. "Ouija" is a trademark of Hasbro, but is often used generically to refer to any talking board.
