If the face projects outward from the wall, due to the thickness of the board and/or a cabinet in which it is mounted, the oche must be moved back appropriately to maintain the required distance. The regulations came about due to the United Kingdom and the rest of the world playing at different lengths, with 7 ft 9¼ inches (2.37 m) being the compromised length. The standard dartboard is divided into 20 numbered sections,

In Europe, the spear-thrower was supplemented by the bow and arrow in the Epi-Paleolithic. Along with improved ease of use, the bow offered the advantage that the bulk of elastic energy is stored in the throwing device, rather than the projectile; arrow shafts can therefore be much smaller, and have looser tolerances for spring constant and weight distribution than atlatl darts. This allowed for more forgiving flint knapping: dart heads designed for a particular spear
