Believed to have originated from soldiers throwing short arrows at the bottom of a cask or tree trunk, the sport of darts is supposed to have started when the first dartboard was made from this wood. As this wood dried some cracking would develop, which would explain the section design of the modern day dartboard. In due course a conventional set of rules were adopted and a standard board design agreed upon. Nowadays darts is immensely widespread as a bar activity, a league game and an internationally popular competitive sport.
