Abstract
A dart board includes a scoring area having a number of triangular holes formed by a number of triangular peripheral walls. The triangular peripheral walls each includes three tapered surfaces formed in the inner peripheral portion so as to form a wider front portion and so as to form a narrower rear portion such that the holes each includes a widely opened front portion for effectively receiving and for guiding a dart into the holes. The narrower rear portions of the holes each includes a size smaller than that of the dart for stably retaining the dart in place.
