Igor Oh, I just noticed this picture, maybe this 666 is a pun.
I didn't know 666 had this meaning in the West before, thank you for your reminder.

I think, based on the pictures, it is indeed what you mentioned, but for us Chinese players, it is more about thinking "great, very smooth", after all, the achievement of "666" is also difficult to achieve.
Perhaps it is precisely because this achievement is so difficult, like a devil (I don't know if this statement is appropriate)
