If tied after regulation: sudden-death overtime (variable format by edition); Common: extra time period focused on submission attempts; or referee decision based on aggression + activity
Why people argue about this
People often assume that sudden-death in ADCC means every submission attempt counts for a win immediately, which leads to overzealous grappling leading to potential injuries or unfair advantages. However, the confusion arises because the referee still makes decisions based on aggression and activity, not just submissions, ensuring fairness and safety despite the time pressure.
