Board used in the coven's third trial in "Agatha All Along" (5)

I believe the answer is:

ouija

(Other definitions for ouija that I've seen before include "This board is used by spiritualists and seances" , "Board sometimes used at seances" , "Occult board" , "This board is used in spiritualistic sessions" , "Board for contacting spirits" .)

I've seen this clue in the USA Today.
