A double bull's-eye device adapted to be incorporated within a circular rib formed on a dart frame, comprising:
- a base having a top end and a bottom end engageable with the circular rib, and said base being independent of said circular rib;
- an outer bull's-eye independent of said base and sleeved from an outer surface of said top end on said base;
- and
- an inner bull's-eye independent of said base, passing from said top end through said base to be mounted on said base and separated from said outer bull's eye by said base.
A dart board apparatus, comprising:
- a dart frame having a circular rib;
- a base having a top end and a bottom end, said base being engageable with said circular rib, and said base being independent of said circular rib;
- an outer bull's-eye sleeved from an outer surface of said base and directly engageable with said circular rib so as to be axially retained in position by said circular rib;
- and
- an inner bull's eye passing from said top end through said base so as to be mounted on said base and separated from said outer bull's eye by said base.
