At present, no country has promised to hold an open unrestricted fighting competition. Unrestricted fighting competition is also called irregular competition, which is generally called black boxing. Western countries and Thailand have this kind of competition, but it will not be announced because it is a black market. Of course, there is a video of Muay Thai in the movie, which is an unlimited competition. You can use any style of play, including flying kick, elbow stroke, kicking crotch, hitting eyes, and you can also use a knife or any tool or instrument, many of which will cause disability or death. In the United States, it is also called cage competition, which means that there are no rules and no time limit until a person can't move or die, because it is exciting and a gamble that can win or lose. Usually in a very hidden place, you still need acquaintances to go in and see it.

At present, there are restrictions on competitions or public competitions, as well as time limits, and many of them are judged by scoring, such as China's martial arts, boxing, Muay Thai, Taekwondo, judo and fighting in the United States or the world. Fighting is one of these games, and there is no real game yet, because the probability of casualties is very high and limited. Although there is fencing, they all wear heavy protective clothing and fight.

In ancient times, there were many unrestricted fights, mainly in ancient Roman stadiums, but basically slaves were fighting, such as Spartacus, while Britain or the United States had swords or one-on-one fights, but rarely.

There are unlimited competitions in China, but in terms of chivalry, there are rules in officialdom. For example, if a person falls to the ground and the other person uses a weapon such as a sword, this usually means giving up. If you sneak up from the rear after giving up, you will usually be shot to death with an arrow, or many people will be hacked to death. There are generally no rules in the private fight for Hao or the thunder platform in the19th century, such as Hao and Huo Yuanjia, but as long as one party gives up, it can't fight any more, that is, slapping the ground of the ring with his hand or throwing a piece of white cloth or towel.

So there is no unlimited fighting competition now, but the black market still exists.
