  • The fight is scored by three judges on a ten-point must system (The winner of each round receives ten points, and the loser receives nine or less. If the round is even, both competitors receive ten points).

  • If there is a draw after three rounds, the judges’ scores are thrown out and one or two extra three-minute rounds are contested.

  • The judges’ decision will then come from the scoring of each extra round only. If, after the extra round(s), there is still a draw, the judges will decide a winner based on the flow of the entire match, considering even the slightest difference.

  • A fight can only end in a draw if both fighters go down at the same time and cannot get up, or in the case of accidental injury in the late stages of the contest.

  • The three-knockdown rule is in effect (three knockdowns in a round results in a technical knockout).

  • The mandatory eight count is in effect (the referee must count to at least “eight” on all knockdowns).

  • The standing eight count is in effect (the referee has the right to declare a knockdown on a fighter who appears to be in a dangerous condition to continue in the match).

  • A fighter can be saved by the bell only in the last round.

  • In K-1 single elimination tournament matches:

  • Each match is three rounds in duration.

  • The three-knockdown rule becomes a two-knockdown rule for all matches except the final.

  • One or two reserve fights are held prior to the single elimination matches. If for any reason a fighter who wins and advances through the brackets is unable to continue, a reserve match competitor, or the fighter’s opponent from the most recent match, takes his place.

    The following restrictions apply to the usage of the backspin blow.
    When it is evident that the attack was made by an elbow, forearm or glove, the attack is considered as a foul In case the referee cannot determine whether the backspin blow was made by the any  none authorised area or not, the match shall be stopped, and the rules director, supervisor, supervisory staff, and the referee and the judges shall review the fight by reviewing the Video Replay, if necessary. When it is determined that the attack was made by the unauthorised blow, the backspin blow is considered as a foul, and the fighter shall be penalised or disqualified at referee discretion.

    1. A fighter who executes a foul technique shall be penalised with a “caution”, “warning”, or a “point deduction”. The referee announces a “caution” and “warning” verbally. (2) cautions shall lead to one (1) warning; any warning then on shall be given instead of cautions thereafter. Two (2) warnings shall lead to a one (1) point deduction, and three (3) point deductions in one (1) round shall be grounds for disqualification.


    However, this clause shall not apply in cases where the referee rules that the foul technique as unintentional. If the referee judges that the foul technique is malicious or causes significant damages on the opponent, the fighter might be given point reduction immediately, skipping order of foul calls.


    The following behaviour is considered as foul techniques.

    1. Using the head to deliver a blow.
    2. Using the elbow to deliver a blow.
    3. Attacking the opponent in the groin (knee kicking or punching the opponent in the area under the navel shall be considered as low-blows and will be ruled as fouls).
    4. Delivering wrestling or judo throwing or submission techniques.
    5. Thumbing the opponent
    6. Choking and punching the throat of the opponent.
    7. Biting the opponent.
    8. Attacking the opponent while he is down or in the process of getting up.
    9. Attacking the opponent after the referee calling a break.
    10. Holding the ropes to whether offensively or defensively.
    11. Using offensive or insulting language to the referee.
    12. Attacking the back of the head with a punch (the side of the head and the area around the ears are not considered as the back of the head and are valid target areas).
    13. Attempting to cause the opponent to fall out of the ring.
    14. Voluntarily exiting the ring during the course of a match.
    15. Attacking the opponent who turned around and showed his back. However, the referee may give a caution, warning or point reduction to the fighter who showed his back as loosing his will to fight.
    16. Delivering a backspin blow with elbows, forearms or glove and giving damage to the opponent.

    A point reduction may be given immediately to a fighter if the referee finds that the foul technique was inflicted with malicious intent.


    A caution shall be given to a fighter who repeatedly charges inside the opponent’s arms, with his head held low (i.e. to avoid attack). This shall be considered as inducing a head-butt. In case that either of the fighters gets a cut from a head-butt and is bleeding, the fighter who has caused the cut shall receive a one (1) point deduction. However, if the referee finds the head-butt to have been obviously intentional or malicious, a deduction of two (2) points shall be given. If the referee judges the head-butt as accidental, there may not be any point reduction.


    A caution, warning, and a point reduction shall be given to a fighter who repeatedly uses holding and clinches that are not accompanied by attacks, and are judged as being defensive/passive in nature (ie. to avoid attack). Two (2) cautions will sum up to one (1) warning, and the next caution shall be a deduction of one (1) point. Furthermore, the same applies to when grasping and holding the opponent immediately after launching an attack (ie. to avoid a counter-attack.), or falling on the matt intentionally.


    A caution, warning, and a reduction of point may be given to the fighter when a fighter is only waiting for a counter blow and is delivering few attacks, and is considered to be passive.


    Holding the kicking leg of an opponent is not a foul, but only a single attack, whether a punch or a kick while holding the leg is authorised. Continuous attack while holding a leg is a foul. If a fighter does not take any action while holding the kicking leg, the referee shall call a break. Holding the kicking leg and using a throwing technique is also a foul.


    When a fighter is holding a neck of his opponent with both hands, the fighter is limited to kick or knee kick his opponent to only one time. Therefore, continuous attack is judged as a foul. Attacking the opponent continuously while holding the neck with one hand is authorised. However, referee may call a break if judges the attack does not give any damage to the opponent.


    Passive holding or clinching is prohibited. However, the referee can permit it only when it is accompanied by an authorised attack. A fighter can be penalised if he resorts to holding or clinching after an authorised attack or in order to avoid attacks.
