The World B-Boy Series is a b-boy championship series established in 2013 that connects ten different renowned solo international b-boy competitions worldwide. At the end of each year, since 2014, the winners of each solo event meet in a new masters event called "Undisputed" and compete to establish who is the "Undisputed" champion. Before 2014, each international b-boy competition would crown their own individual world champion but with the creation of the World B-Boy Series and Undisputed, a supreme world champion can be crowned.
Undisputed utilizes a round-by-round judging system, which allows participants to see the judges decisions after every round. The first round of Undisputed is a round-robin tournament this system was used in 2014 and 2015. For the Undisputed 2016 a system of pre-rounds was used in which each participant battles 3 opponents and receives points for a battle victory. Also the number rounds and votes the participant won in his battles are counted. After 3 battle rounds the top 4 participants of the ranking advance to the semi finals and finals.
