circular disc as best seen in fig1 having a forward target surface 42 shown in fig4 which latter is vertical and at a right angle to an axis of rotation 50 seen in fig2 the surface 42 is formed of a material suitable for the penetration thereof by pointed ends of darts such as the dart 50 of fig1 so as to support and retain darts stuck therein in the usual manner since the target 40 is free to rotate about the axis 50 then any excess of darts stuck into the target 40 on the right side of a center line 60 will tend to cause the target 40 to be weighted downwardly on its right side so that the center line 60 which is normally vertical as shown in dotted lines in fig1 will have moved to the full line position in fig1 whereby the victory by the player who has the most strategically placed darts on the right side of the board will be indicated by an arrow 70 shown on the forward side of the target 40 as read against a scale shown at 72 in fig1 so as to indicate a score achieved by the player throwing at the right side of the board conversely if the player throwing at the left side of the board should have superior dart positions in number or in distance from the axis 50 then the arrow 70 would be disposed beneath a zero score point and in an area on the scale 72 showing the score achieved by the.
