K-1 World Grand Prix, also known as the K-1 WORLD GP, is an elimination kickboxing tournament that was originally held annually from 1993 by the K-1 organization, under the ownership of the Fighting and Entertainment Group (FEG). Each year, K-1 would hold various 16-men, 8-match grand prix style qualifying tournaments throughout the world to determine which 16 fighters will compete in the main World GP.
Combatants of the quarter-finals of a 16-man 8-match tournament were paired by drawing, with the exception of the final.[citation needed] A lottery draw would take place. The balls represented numbers 1 to 8, which determined the fighters' order in choosing a position (from A to H), and the line-number of the match. The next fighter was able to choose between challenging the one on the stage or an "empty" section. This procedure went on until one fighter had to fill its slot left next to the lone rival.[citation needed]
