- 1) How do you win a match. What is the main objective.
- 2) Who are you competing with (Weight classes? Age groups? Gender?

- 4) What is not allowed and why not? (Over all picture)
- 5) Duration of a match?
So the list would be Freestyle Judo, Freestyle wrestling, Freestyle Sambo, Kosen Judo, BJJ gi and submission wrestling. (I'll start with gi styles and if it's not too much work do the nogi stuff too.)
I am using this page to collect information of gi grappling styles to make an overall list of rules.
