ADCC (the Abu Dhabi Combat Club Submission Fighting Championship) is the elite, invitation-and-qualifier world championship of submission grappling, founded in 1998 by Sheikh Tahnoon Bin Zayed Al Nahyan. Held roughly every two years across weight classes plus an absolute division under "neutral rules" designed for BJJ, judo, wrestling, and sambo athletes to compete head-to-head, it's widely regarded as the top championship in the sport. Its regional ADCC Trials events are the qualifier tournaments grassroots competitors can actually enter.
The ADCC ruleset is built to reward submission hunting over point management. During the first half of regulation no points are scored at all — competitors are free to attack without positional risk showing on the scoreboard. Points switch on for the second half, scoring takedowns, guard passes, mount, and back control.
The scoreboard can also go negative: stalling, pulling guard without engaging, and refusing to fight for position draw negative points, which makes prolonged inactivity a losing strategy. Combined with a legal-technique list that is wide open at the advanced level (including heel hooks in the adult divisions), ADCC-rules events tend to produce aggressive, submission-first grappling.
Always confirm the official rulebook before you compete — organizations update rules between seasons. See the official event page for current rules.
