How to play Kuji in Japan?

Excuse me, could you please elaborate on the steps to play Kuji, the traditional Japanese divination game? I'm quite intrigued by its origins and how it's practiced in Japan. Is there a specific ritual or set of instructions that one must follow? I'm eager to learn more about the meanings behind each of the Kuji-in symbols and how they're interpreted. Additionally, are there any cultural nuances or superstitions associated with playing Kuji that I should be aware of? Your insights would be greatly appreciated.
