Three darts are thrown at the board. The dart scores according to what area it lands in. It can score the value given by the number at the edge of the sector it lands in. If it lands in the "double" area (the outer green and red band) then this score is doubled. If it lands in the "treble" area (the inner green and red band) then this score is trebled. The bull (red) scores 50, and the outer bull (green) scores 25.
