Von 2013 NAGA GERMANY GRAPPLING CHAMPIONSHIP:
" TOURNAMENT RULES
NAGA has received input from European competitors and instructors concerning our rules. NAGA has listened to these suggestions and has decided that
heel hooks in all divisions will be illegal at this event. We understand that this is a common rule in Europe and are willing to make this change. Children and Teens will be allowed to do submissions (except for Children Novice competitors). The NAGA Rulebook and Rules Videos (both only in English) can be found at www.nagafighter.com."
