How can a person ask the spirits of the spirits?

Basically, one person can't be invited. It must be two people. What I learned is that two people's hands are opposite and their fingers are crossed. When their hands are pulled by an invisible force without strength, they can ask questions. If you ask "no", you don't have to write it. The circle is "yes" and the cross is "no". If not, you should write down the answer options on paper.

Playing with classmates in junior high school, the answer is ridiculous. In fact, the invisible power is only because two people's fingers cross, and the surrounding nerves will tremble by themselves, so that something can be drawn, which is not to ask the spirits at all.

If you can only play alone, there seems to be another kind of vegetable fairy, using plates. I haven't played it before. You can check how to play it.

And there is a good book, which I recommend you to read.
