Circle rules football, circle rules in short, is a sport loosely derived from association football. The sport was invented in the United States rather recently in 2006 and has spread to several cities within the country.
The sport is played on a circular field. There is just one goal post in the middle of the field through which goals are scored, but both teams should score in opposing directions. A large inflated ball similar to a stability or yoga ball is used for playing. A circular area, called the key, is marked around the goal post, which is restricted for only goal keepers to enter.
A match is played between two 6-player teams. One player from each team is designated as the goal keeper. The objective of the sport is to score as many goals as possible. Players are allowed to move the ball by any means possible, which includes, kicking, dribbling, rolling, carrying, or throwing. The only restriction is that players are not allowed to hold the ball with both hands or against their body.
Matches are played for four 15-minute periods. The team with the most goals at the end wins the match. Five-minute extra time plays are used in case of a tie.

- Association Football — more commonly known as Football or Soccer. It is the world's most popular sport, played between two teams of eleven players with a spherical ball.

- Bladderball — a traditional game played between 1954-1982 at Yale University. The game resembled other forms of mob football in which any number of people can be a part in each team, and the only objective of the sport was to gain possession of the large inflated leather ball by any means necessary.
- Crab Soccer or Crab Football — players kick a large inflated ball while supporting themselves on their hands and their feet, face up, which makes them look like crabs.
