GLORY is the largest international kickboxing promotion and uses a K-1 derived ruleset that sits between full Muay Thai and Western boxing. Its rules are designed for a fast, exciting, predominantly striking-on-the-feet format that minimises the slow tactical phases that traditional Muay Thai allows.
The K-1 style ruleset
GLORY uses 8-oz boxing gloves, full-contact strikes with fists, kicks and knees, but bans elbows entirely. There are no takedowns and no ground game. The clinch is permitted only briefly: fighters who enter a clinch are allowed one immediate strike (typically a knee) and then must break, or the referee will separate them. Sustained clinch work — the central pillar of traditional Muay Thai — is not allowed. Sweeps and throws are not permitted. The result is a ruleset that rewards constant motion, combination striking and ring control.
Round structure
Standard GLORY non-title bouts are 3 rounds of 3 minutes with 1-minute rest periods. Title fights and selected main events are 5 rounds of 3 minutes. A drawn title fight may go to an additional extra round (a sudden-death "extension round") under the title rules.
Scoring criteria
GLORY uses a 10-point must system with three judges. The winner of each round gets 10, the loser typically 9, and 10-8 is used for a round with a knockdown or extreme dominance. Judges are instructed to weigh effective striking (clean, hard, accurate strikes that affect the opponent), ring generalship (control of the fight's pace, distance and location), defence (slipping, blocking, evasion), and aggression (forward, finish-seeking movement). Unlike traditional Muay Thai, all legal techniques score on roughly equal merit by impact rather than by a hierarchy that privileges kicks over punches; a clean cross that visibly hurts the opponent scores at least as well as a clean kick of similar effect.
Knockdowns and 8-counts
A knockdown — any moment when the opponent is dropped by a legal strike — automatically forces a 10-8 round at minimum and triggers a standing 8-count from the referee. Three knockdowns in the same round end the fight by technical knockout. A fighter knocked out for the count of 10 loses by knockout. The referee can also stop the fight at any time, and the ringside physician's authority is final on medical grounds. Standing 8-counts can also be administered when a fighter is hurt without being dropped, at the referee's discretion.
The four-corner tournament format
Historically, GLORY ran one-night, single-elimination, four-fighter tournaments ("Last Man Standing" and similar formats) descended from K-1's classic tournament structure. A fighter would need to win three fights in a single evening to take the tournament, with reserve fighters available in case of injury between rounds. This format has become less central to GLORY's regular schedule in recent years but is still occasionally used for special events and remains part of the promotion's brand identity.
Weight classes
GLORY's male divisions run from featherweight (65 kg / 143 lb), through lightweight (70 kg), welterweight (77 kg), middleweight (85 kg), light-heavyweight (95 kg), to heavyweight (over 95 kg, with no upper limit). Female divisions are slightly more compressed and have grown in recent years. Weigh-ins are typically the day before, with a 1-2 kg allowance depending on the division and bout type.
How GLORY scoring differs from traditional Muay Thai
Three differences stand out. First, GLORY scores round by round on a Western 10-point must basis; traditional Muay Thai scores the bout cumulatively, with rounds 3-4 weighted most heavily and round 1 effectively a feeling-out period. Second, GLORY does not impose a hierarchy that prioritises kicks over punches; a high-output boxer who scores cleanly can win a GLORY decision in a way they would not win a stadium Muay Thai decision. Third, GLORY's near-elimination of clinch work removes one of Muay Thai's defining scoring phases entirely — there is no path to victory in GLORY through controlling the clinch and landing knees from it for round after round, because the referee will break the fighters every few seconds. The result is two ostensibly similar sports that reward genuinely different fighters: GLORY rewards constant-output combination strikers with strong defence and ring control, while traditional Muay Thai rewards balanced, technical fighters who can dominate the clinch and land scoring kicks throughout a longer narrative arc.
How a fight ends
A GLORY bout ends by knockout, technical knockout (referee or doctor stoppage, three knockdowns in a round, or the corner throwing the towel), decision after the final round, disqualification for repeated fouls (illegal elbows, low blows, attacks during the break, holding without striking) or no contest if the fight cannot continue due to an accidental injury or other circumstance outside either fighter's control.
