The Sport of Rugby Union as defined on Wikipedia. Do you know what a prolate spheroid is?


Rugby union football (often referred to as simply rugby or union) is an outdoor sport played by teams of 15 players with a prolate spheroid-shaped ball. It is one of the two main forms of full-team rugby, the other being rugby league. There is also a quicker seven-a-side sport called rugby sevens, which exists in both rugby union- and rugby league-derived forms.


The game was developed from the rules used to play an early form of football at Rugby School in England, hence the name. The crucial differences from association football (soccer) are that in rugby the ball is a prolate spheroid instead of a sphere and the players are allowed to pick the ball up and run with it. The players may kick the ball, and also are allowed to throw (pass) the ball from player to player, but unlike in American football they may not throw it forward; i.e. the ball must only go backwards or laterally when thrown or passed.
