The playing area must have the following measurements:
Total Length: 31 meters (including both team in-goal areas of 3 meters each)
Total Width: 25 meters.
 The teams are made up of 5 ‘in-field’ players, 5 replacements are admitted and interchangeable at times during the match without any need to call for the referee’s permission, although the interchange must take place only during a standstill of play. In this event, players may enter the field a single time approx. 1 meter from the enclosure in a central position, although they may exit from whatever position. As soon as the referee becomes aware that a team has more than 5 players on the field, he may disallow any action that has taken place in the meantime, unless the opponent team have gained an advantage (Ex. 1: a try is scored and the defending team has 6 players on the field: the score stands. Ex. 2: a try is scored and the attacking team has 6 players on the field: the try is disallowed)
 Only the recognized captain may report to the referee to ask for explanations or flag serious infringements such as the opponents having 6 players on the field.
 The try is worth one point and there are no goals after a try.
 The ball used in the game shall be a no. 4 type.
 It is not allowed to kick the ball.
. Line-out and scrummage are eliminated and play is reassumed by a free kick.
 When the player carrying the ball is caught by the opponent, from that point, he must release the ball within 2 seconds by passing it over or leaving it to anybody’s disposal. If this rule is not observed, his/her team will lose possession of the ball.
 After scoring a try, the ball will be free-kicked from the middle of the field by the team suffering the try, quickly if the ball has been brought to the In-goal without any forward passes; otherwise, they will have to wait until the opponents have taken their positions.
 The distance from the ball for penalty kicks or kick-off shall be 5 meters. Penalty: If this distance is not observed, the referee will ascribe a further 5-meter penalty to the player.
 A match consists of two halves of 5 minutes each with a 3 minutes’ interval.
 In case a match ends in a draw, an additional limitless period will be played under the sudden-death rule, i.e. the fist scoring team is the winner.
 In case some teams rank with the same score during qualification rounds, the team with the highest number of tries will qualify (regardless of their type); in case parity should persist, the type of tries will count; persisting the situation of parity, will be preferred the team with fewer registered players and finally the younger team (obtained by summing up the players’ years of birth and then dividing them by 12).
 When an attacking player carries the ball into in-goal or over the goal line that player has three seconds to score a try. Penalty: A free kick is awarded to the opposing team 5 metres from the goal line.
 When an attacking player scores a try that player must leave the ball at the place where the try has been scored. Penalty: A free kick from the centre of the half-way line is awarded to the opposing team and the offending player will be cautioned and temporarily suspended.
 All the players shall wear tear-resistant jerseys and NOT T-SHIRTS with the players’ numbers or names on the back; the jerseys will be homologated at the beginning of the Championship by a Technical Commission formed by the Championship Manager and/or L.I.B.R. representative and a referee. The homologation process will be repeated for each Championship even though the jerseys have been previously deemed appropriate.
