Give some stream of consciousness and then the answer. A regulation board is ​ 17 ⁄ inches (451 mm) in diameter and is divided into 20 radial sections. Each section is separated with metal wire or a thin band of sheet metal. The best dartboards have the thinnest wire, so that the darts have less chance of hitting a wire and bouncing out. The numbers indicating the various scoring sections of the board are also normally made of wire, especially on tournament-quality boards. The wire ring on which the numbers are welded can be turned to facilitate even wear of the board. Boards of lesser quality often have the numbers printed directly on the board.\n\nWhat do the numbers on a dartboard mean?
