Matches last 50 minutes and are played on a field covered in sand, twice as long as it is wide (approximately 100 m × 50 m or 109 by 55 yards). A white line divides the field into two identical squares, and a goal net runs the width of each end.

Each team has 27 players and no substitutions are allowed for injured or expelled players. The teams are made up of four datori indietro (goalkeepers), three datori innanzi (fullbacks), five sconciatori (halfbacks) and 15 innanzi or corridori (forwards). The captain and standard bearer’s tent sits at the center of the goal net. They do not actively participate in the game, but can organize their teams and occasionally act as caccas (referees), mainly to calm down their players or to stop fights.

The referee and the six linesmen officiate the match in collaboration with the judge commissioner, who remains off the field. The referee, above everyone else, is the master of the field, and is responsible for making sure the game runs smoothly, stepping into the field only to maintain discipline and reestablish order when fights occur.

Shots from a small cannon or colubrine announces the beginning of the event. The game starts when the pallaio[clarification needed] throws and kicks the ball toward the center line, then at the first whistle as the ball first rests on field, 15 forwards or corridori, begin fighting in a wild mixed martial arts match- punching, kicking, tripping, hacking, tackling, and wrestling with each other in an effort designed to tire opponents’ defenses, but which often descends into an all-out brawl. They try to pin and force into submission as many players possible. Once there are enough incapacitated players, the other teammates come and swoop up the ball and head to the goal.

From this moment on, the players try by any means necessary to get the ball into the opponents’ goal, also called “caccia”. The teams change sides with every caccia or goal scored. It is important to shoot with precision, because every time a player throws or kicks the ball above the net, the opposing team is awarded with a half caccia. The game ends after 50 minutes and the team which scored the most cacce wins.

Along with the palio, the winning team used to receive a Chianina, a type of pure-bred cow. However, this has been reduced to a free dinner for the winning team; the players earn no other compensation.
