Chogan, better known as polo, was one of the oldest and most widespread team sports of it's time. Historians find the game being played as far back as 2500 years ago. As a game played with two teams on horses hitting a ball with a stick to through the goal posts on opposite sides of a playing field, it is assumed that the best horse riders could play this game extraordinary well and have amazing versatility on the field. Polo was also called "The Game of Kings" because it was one of the few games played by kings and their armies for training and for entertainment.
The playing field today is about 300 yards long and 160 yards wide. On either side of the field are two goals, 8 feet apart. The goal of the game is to score as many points as you can before the chukkas(rounds) finish. In each full game there are 8 chukkas, although some smaller and less committed and serious players play with 4 or 6 rounds. Each chukka lasts around 7 minutes. When the 7 minutes are up the ball is still in play until it is knocked out of bounds or the the bell rings again at which the ball is left exactly where it is by the players until the next chukka.
On the field, there are no more than 4 players on each team playing at once. They are often seen as having decisive positions and roles on a team which are hard to make out to onlookers who do not know what each of the players jobs are. The 2 attackers are always on the offensive trying to score a goal, the defense is always on defense trying to deter the opponents attackers from scoring, and the mid-field man has the most versatility since he helps where help is needed.
In the past the game was played with any amount of people on each side. Almost every ancient society with horses played the game. The first game was recorded in Persia and the word polo comes from Tibet. It means "ball" or "ballgame." Polo is one of the few sports that actual kings participated in rather than watched like the gladiator games. Traces of the games has been fond everywhere from Asia to Modern Middle East. At one point the game was recorded to have been played with 200 people at the same time and involved tackling if the ball was picked up with the hands.
The design of this game is fairly simple in the way it is constructed somewhat like soccer. The part that is amazing is that this is the first team sport game recorded. To know that such a complex game was created without having a a game as a model is truly one of the most unique things in game design. It is a sign of true genius.
The objective is clear in the game and simple but the strategy involved in getting the points is endless. Any amount of effort can be put into findig the best way to move from one side of the field to the other to be able to score. The limitations of the game is set by the penalties of dangerous play in the modern version, the 8 chukkas and 7 minutes the player has to score, and the field of play around them making nothing confusing of what you can and can't do.
This is clearly a scoring type game like soccer and football just at a much faster pace.
The only art one can really say is in this game is the shapes of the polo sticks and the colors that the players wear to set them selves apart and show what team they are on.
