Darts

Darts are indoor game commonly played in the United Kingdom ( the first country recognise as a sports).

Darts are thrown at a circular target (dartboard) hung on wall with the height of 1.7 meter (5'8") from the floor to the bulls eye (center of the Dart board). Though various different boards and game involving a specific board design and set of rules. The distance of the dart from the face of the dartboard to the throwing line is 2.37 meter (7' 9 1/4 ") measure horizontally. This became the world standard as set by World Dart Federation and played in the competetion.

The dartboard is divided into 20 numbered equal sections, with numbers mark as 1-20 with traditionally alternately coloured black and white. Hitting the thin outer portions of these sections, coloured red and green, scores double the points value of that section. Hitting the thin inner portions of these sections, roughly halfway between the outer wire and the central circle and again coloured red or green, scores triple the points value of that section. The central circle is divided into a green outer ring worth 25 points (known as "outer", "outer bull", or "iris") and a red inner circle (usually known as "bull", "inner bull" or "double bull"), worth 50 points. The term "bullseye" can mean either the whole central part of the board or just the inner red section. The term "bull's ring" usually means just the green outer ring. The sport of darts is usually contested between two players who take turns in throwing up to three darts. Starting from a set score, usually 501 or 301, a player wins by reducing his score to zero. The last dart in the leg must hit either a double or the inner portion of the bullseye, which is the double of the outer bull, and must reduce the score to exactly 0. Successfully doing so is known as "doubling out" or "checking out". A throw that would reduce a player's score to less than zero does not count, his turn ends, and his score is reset to what it was before that turn. Since the double areas are small, doubling out is usually the most difficult and tense part of a leg. Longer matches are often divided into sets, each comprising some number of legs. Although playing straight down from 501 is standard in darts, other variations exist, notably "doubling in", where players must hit a double to begin scoring, with all darts thrown before said double contributing nothing to their score.

Other games that are commonly played differ in their scoring methods. The "Killer" is one of the most known game of the darts.
