The Ouija board (// wee-jə) 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", "hello" (occasionally), and "goodbye", along with various symbols and graphics. It uses a planchette (small heart-shaped piece of wood) or movable indicator to indicate the spirit's message by spelling it out on the board during a séance. Participants place their fingers on the planchette, and it is moved about the board to spell out words. "Ouija" has become a trademark that is often used generically to refer to any talking board.
Following its commercial introduction by businessman Elijah Bond on July 1, 1890, the Ouija board was regarded as a harmless parlor game unrelated to the occult until American Spiritualist Pearl Curran popularized its use as a divining tool during World War I.
Mainstream religions and some occultists have associated use of a Ouija board with the concept of demonic possession, and view the use of the board as a spiritual threat and have cautioned their followers not to use a Ouija board.
Despite being criticized by the scientific community and deemed demonic by Christians, Ouija remains popular among many people
