He mentioned

3 = Time

6 = Rotation

9 = Space

8 = Cosmic Balance

I didnt found any explantionn on Time Rotation and space. As per my thinking, 6 is number of spins to play, and 9 is your total space of numbers . and 8 is miimum numbers to bet on, but how to play, if play with Orochi nmbers then 4 nmbers and their partner number ..i guess, he put very simple play , but not much explanation
