I went to daily Liturgy with a priest who was assigned by the bishop to be an exorcist for 2 provinces and he was busy. At least once a year he would do a homily on things to stay away from, and certainly ouiji boards were on the list. Not even keep it in the house.
Personally, I would destroy it and get either blessed salt or holy water and go through the house. I’m not kidding.
Although an outsider might consider that to be superstition, scripture says
Put on the armor of God so that you may be able to stand firm against the tactics of the devil. Our battle is not against human forces but against the principalities and powers, the rulers of this world of darkness, the evil spirits in regions above. Eph 6: 11 and 12
When we use water to baptize, we believe God is there with His power, it’s not water in itself that has the power to save. Likewise, an ouiji board may be made of wood and paint but the enemy can use that to his advantage over us. It is prudent to be aware that there are powers we cannot see influencing people through the world. We should not open the door to it.
