I used to play it when I was in 3rd grade. My older sister had one, and my cousin and I knew about it and we knew what it does and what it meant. We played it and nothing really happened. We didn't do it professionally either (lighting candles, in the dark, etc.) but I heard that if you break it, spirits starts screaming
Edit: My older brother didn't like that fact that the Ouija was in our house, so he took it out my sister's room and broke that ****. He said it screamed.
