A ring is described carrying the numbers for identifying the segmental zones of a dartboard. The ring is of a resiliently deformable material such as rubber and comprises a first flange which projects outwardly from the periphery of the dartboard and a second flange disposed at right angles to the first flange and overlying the periphery of the dartboard. The first flange has an annular face on which the numbers are moulded. The first flange can yield when struck by a dart and the material is sufficiently soft to avoid damaging the points of darts which strike the ring. <IMAGE> |
