K-1 World Grand Prix

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.

Match-ups
Combatants of the quarter-finals of a 16-man 8-match tournament are paired by drawing, with the exception of the final in the Tokyo Dome.

A lottery draw would take place in the beginning, with fighters pulling a ball from a glass bowl. The balls represent numbers 1 to 8, which determine the fighters' order in choosing a position from a giant tournament tree figure by standing in front a drawn bracket (from A to H) on the poster, which represents the fighter's corner-color and the line-number of the match. The next fighter does the same, but is able to choose between challenging the one on the stage or an "empty" section. This procedure goes on until one fighter remains who has no choice but to fill one slot left next to the one lone fighter.
