Here are the three main ones: Free-for-all rules. In this rule style, there are no restrictions on what positions wrestlers can be put in during a match. Whoever gets to the mat first wins that round. Loser leaves the ring. In this rule style, if one wrestler loses by fall, he or she must leave the ring or be counted out. Time limit rules. In this rule style, there is a set amount of time that a match lasts. If either wrestler does not get to their feet before the end of the time period, then they lose.
