There are many types of Jiu-Jitsu. Apart from traditional Jujutsu and Brazilian Jiu-JItsu, there is Sports Jujutsu which is organized by Ju-Jitsu International Federation (JJIF), and has been recognized an official sport of the World Games.
According to Wiki, Sport Jujutsu comes in three main variants: Duo (self-defense demonstration) where both the tori (attacker) and the uke (defender) come from the same team and demonstrate self-defense techniques. In this variant, there is a special system named Random Attacks, focusing on instilling quick reaction times against any given attack by defending and countering. The tori and the ukeare also from the same team but here they don’t know what the attack will be, which is given to the uke by the judges, without the tori’s knowledge.
The second variant is the Fighting System (Freefighting) where competitors combine striking, grappling and submissions under rules which emphasise safety. Many of the potentially dangerous techniques such as scissor takedowns, necklocks and digital choking and locking are prohibited in Sport Jujutsu. There are a number of other styles of sport jujutsu with varying rules.
