Darts General Rules
The game area is an estimated five by eleven feet free space. To avoid injuries, only players should be allowed in the game area; the audience should be made to stay back at a considerable distance.

The board is hung five feet and eight inches from the floor with the distance from the board to the throw line set at seven feet and nine and a quarter inches. The throw line may be marked by a tape or a commercially available throw line sticker.

There should be proper lighting especially in indoor-held dart games. Ideally, two lamps mounted to the left and right of the board would suffice to provide good lighting for the game.

As with other sports, sportsmanship is a virtue. Listed below are the general technical guidelines:

• The darts should not exceed an overall length of 30.5 cm. and should not weigh more than 55 grams.
• Generally, playing order is decided by throwing darts onto the board. The one who throws his dart closest to the Bullseye gets to shoot first.
• Each turn is equivalent to throwing three darts.
• There should be no distractions. Nobody should talk to the player who is shooting.
• Only the caller, referee, or a teammate should tell the shooter what has been hit. No one but a teammate can coach a shooting player.
• The darts should be scored before pulling.
• The scorekeeper determines the score corresponding to the thrown darts. In case of doubt, the players may contend the administered scores.

Scores are given only to darts that land on the board. Darts that fall before getting scored or before the player pulls them are not counted. Those that get stuck unto other darts and those knocked out by subsequent throws likewise don’t count as points.

A “double” means landing a hit on the thin outer ring. It is equivalent to two counts or the corresponding score number times two. A “triple,” which equals three counts, can be scored by hitting the thin inner ring. It triples the matching number hit.

Closing a number means to hit it in three counts. It may be through a “triple,” a “double” plus an ordinary hit, or just three ordinary hits.
