Very very dangerous.
Yup, not a toy at all. Many many cases of possession have been attributed to the use of the ouija board the most notable being the case that was used as the basis for the movie the Exorcist.
Anyone who buys a Ouija board for their kid might as well buy him or her LSD or dynamite.
I was talking to my adult daughter last year. She told me about going across the street to see a childhood friend when she was in elementary school. She said she felt really scared when she went into this little girl’s house. She left as soon as possible. Later, she learned her friend had been messing with one of these boards. She is afraid of them. Do not mess with them.
People who buy them have no idea what they are opening themselves up to. Its a conduit to evil. There are countless stories about them bringing about very bad luck and even resulting in death in some instances. When I was young we bought one. It wasn’t long afterwards that my mother had a double aneurism and my father had terminal cancer and died. I never connected the two until watching some some shows about the Ouija board on TV where bad things happened after people bought them (in addition to many other negative things).
