<P> The rules of water polo were originally developed in the late nineteenth century in Great Britain by William Wilson . Wilson is believed to have been the First Baths Master of the Arlington Baths Club in Glasgow . The first games of' aquatic football' were played at the Arlington in the late 1800s (the Club was founded in 1870), with a ball constructed of India rubber . This "water rugby" came to be called "water polo" based on the English pronunciation of the Balti word for ball, pulu . Early play allowed brute strength, wrestling and holding opposing players underwater to recover the ball . Players held underwater for lengthy periods usually surrendered possession . The goalie stood outside the playing area and defended the goal by jumping in on any opponent attempting to score by placing the ball on the deck . </P> <P> The rules of water polo cover the play, procedures, equipment and officiating of water polo . These rules are similar throughout the world, although slight variations to the rules do occur regionally and depending on the governing body . Governing bodies of water polo include FINA, the international governing organization for the rules; the NCAA rules, which govern the rules for collegiate matches in the United States; the NFHS rules which govern the rules in high schools in the USA and the IOC rules which govern the rules at Olympic events . </P> <P> There are seven players in the water from each team at one time . There are six players that play out and one goalkeeper . Unlike most common team sports, there is little positional play; field players will often fill several positions throughout the game as situations demand . These positions usually consist of a center forward, a center back, the two wing players and the two drivers . Players who are skilled in all positions of offense or defense are called utility players . Utility players tend to come off of the bench, though this is not absolute . Certain body types are more suited for particular positions, and left - handed players are especially coveted on the right - hand side of the field, allowing teams to launch two - sided attacks . </P> <P> The offensive positions include: one center forward (also called a "set", "hole - set", "center", "setter", "hole", or "2 - meter man", located on or near the 2 - meter, roughly in the center of the goal), two wings (located on or near the 2 - meter, just outside of the goal posts, respectively), two drivers (also called "flats", located on or near the 5 - meter, roughly at the goal posts, respectively), and one "point" (usually just behind the 5 meter, roughly in the center of the goal, respectively), positioned farthest from the goal . The wings, drivers and point are often called the perimeter players; while the hole - set directs play . There is a typical numbering system for these positions in U.S. NCAA men's division one polo . Beginning with the offensive wing to the opposing goalie's right side is called one . The flat in a counter clockwise from one is called two . Moving along in the same direction the point player is three, the next flat is four, the final wing is five, and the hole set is called six . Additionally, the position in which a player is can give advantages based on a player's handedness, to improve a shooting or passing angle (for example, the right wing is often left handed). </P>
