In order to combat the growing competition for other talking board manufacturers, Fuld knew that if he himself made a cheaper version of his own product he would get more business. In 1919, he introduced the "Mystifying Oracle", an exact replica of his Ouija board that sold for less money. He also launched a line of trademarked Ouija jewelry and Ouija Oil for rheumatism. Fuld also trademarked the names "Egyptian Luck board", "Hindu Luck board" and "WE-JA" as well as a trademark detailing the way the word "Ouija" would be displayed.
