Is there rules to play the ouija board?

There are various rules, but I would not refer to the Ouija board as a "game." You indeed are dealing with real spirits, and maybe even demons around you, and if you go wrong, you could be possessed by a dangerous demon. Hence, not a "game."

Rules:

Never play alone

Do not let the spirit count down through the numbers or the alphabet

Always make the spirit say goodbye

Do not upset or irritate the spirit
