Sambo as a combat system and martial art generates a lot of interest in the United States, but there are very few tournaments and schools to meet the demand. Rdojo is committed to providing as many training opportunities as possible through camps, seminars, and classes, but it is costly and difficult to host large-scale Sambo tournaments in the US. That's where the Rdojo Sambo League came in. The Rdojo Sambo League was a rating system, organizational platform, and standardization method for American in-house Sambo tournaments. The goal was to allow gyms to host small events in their own gyms that can be recorded and ranked at the national level. Each gym's tournament results were featured here and the athletes who participate earned points toward a league ranking. At the end of the year, the highest ranking athletes were awarded sponsored prizes by Inverted Gear.
