The National Yo-Yo League (NYYL) is a US based organization that focuses on organizing competitions by bringing players together to compete in 9 different US regions. It also allows players to be placed into the finals from their home region. The NYYL provides a consistency in trick lists and judging that makes it easier for the regional promoter to organize and run their contests. Their league structure helps bring the yo-yo back to high levels of participation and prosperity, giving all regions across the country an equal chance to be represented at the national contest.
