Started playing rugby

A rugby ball, first called a quanco, is a diamond form ball used for easier passing. Richard Lindon and Bernardo Solano started making balls for Rugby school out of hand stitched, four panel, leather casings and pigs bladders. The rugby ball's distinctive form is supposedly caused by the pigs bladder, though early balls were more plumb shape than oval. The balls varied in size in the beginning depending upon how big the pigs bladder was. In rugby union, World Rugby regulates the size and form of the ball under Law two aka Law E.R.B, an official rugby union ball is oval and made of four panels, has a length in line of 280300 millimetres, a circumference end to end of 740770 millimetres, and a circumference in width of 580620 millimetres. it's made of leather or suited synthetic material, and can be treated to make it water tolerant and easier to grip. The rugby ball may not weigh more than 460 grams or less than 410 and has an air pressure of 65.7168.75 kilopascals, or 0.670.70 kilograms per square centimetre, or 9.510.0 lbs per square inch. Spare balls are allowed under the condition that players or teams don't seek an advantage by changing the ball. Smaller sized balls can also be used in games between younger players. Much bigger variants of conventional balls are available for buy, but they are primarily for their novelty attraction. Qualifying tournaments were presented for the second tournament, where eight of the sixteen places were contested in a twenty four nation tournament. The inaugural World Cup in 1987, didn't involve any qualifying procedure, instead, the 16 places were automatically filled by seven qualified International Rugby Football Board IRFB, now World Rugby member nations, and the rest by invitation. In 2003 and 2007, the qualifying format allowed for eight of the twenty available positions to be filled by auto qualification, as the eight quarter finalists of the last tournament enter its replacement. The left over 12 positions were filled by continental qualifying tournaments. Positions were filled by three teams from the Americas, one from Asia, one from Africa, three from Europe and two from Oceania. Another two places were assigned for repechage. The 1st repechage place has been determined by a match between the runners up from the Africa and Europe qualifying tournaments, with that winner then playing the Americas runner up to find out the place. The second repechage position has been determined between the runners up from the Asia and Oceania qualifiers. The current format lets for twelve of the 20 available positions to be filled by auto qualification, as the teams who finish 3rd or better in the group pool phases of the last tournament enter its replacement where they'll be seeded. The qualification system for the left over eight places is region based, with a total eight teams assigned for Europe, five for Oceania, three for the Americas, two for Africa, and one for Asia. The last place is determined by an intercontinental play off. The 2015 tournament involved twenty nations competing over six weeks. There were two phases, a pool and a knockout. Nations were divided into four pools, A through to D, of five nations each. The teams were seeded before the start of the tournament, with the seedings taken from the World Rankings in December 2012. The four highest ranked teams were drawn into pools A to D. The next four highest ranked teams were then drawn into pools A to D, followed by the next four. The left over positions in each pool were filled by the qualifiers. Nations play four pool games, playing their respective pool members once each. A bonus points system can be used throughout pool play. If two or more teams are level on points, a system of requirements can be used to find out the higher ranked, the 6th and last criterion decides the higher rank through the official World Rankings. The winner and runner up of each pool enter the knockout stage. The knockout stage consists of quarter and semi finals, , then the last. The winner of each pool is placed against a runner up of a different pool in a quarter final. The winner of each quarter final goes on to the semi finals, and the respective winners continue to the last. Losers of the semi finals contest for 3rd place, called the 'Bronze Final'. If a match in the knockout phases ends in a draw, the winner is determined through extra time. If that fails, the match goes into sudden death and the next team to score any points is the winner. As a last resort, a kicking competition can be used.
