Can two or more Ouija boards be used at the same time?

Ouija boards, even when used with protection, and in a sincere way, are dangerous, because the higher spirits do not use this approach to communicate, and the low ones are happy to oblige. You won't get a meltdown, but you will be increasing the risk of attracting something you don't want hanging around. Try this safer method:

Why sure, but nothing would happen. Same as if you used any number of Ouija boards.

These things invite demons into your life...the Bible gives fair warning...

(Deuteronomy 18:10-12) There should not be found in you anyone who makes his son or his daughter pass through the fire, anyone who employs divination, a practicer of magic or anyone who looks for omens or a sorcerer, 11 or one who binds others with a spell or anyone who consults a spirit medium or a professional foreteller of events or anyone who inquires of the dead. 12 For everybody doing these things is something detestable to Jehovah, and on account of these detestable things Jehovah your God is driving them away from before you.

Yes, but be careful because the spirits might start having an Ouija orgy.

Not that my answer is really helpful, and I don't buy into them anyway....

But I can talk on two phones at the same time, as long as I'm very attentive

I will not try this type of ignorancy
