Halve It
For this game, write down a series of targets. If you hit them, you score what you score. If you miss with all three darts, you halve your total score, and if you miss three times in a row you are eliminated.
Let us take a possible sequence: 11, 12, double 13, 14, ‘outer ring’, 15, 16, treble 17, 18, ‘inner ring’, 19, 20, bull or 25 ring.
The outer ring means all three darts must land in the area between the treble band and the 25 ring. Therefore, if you hit a double or treble while throwing for the outer or inner ring, you halve your total score. If you hit a treble or the bull or 25 going for the inner ring, you also have to halve it.
It is amazing how many players fail to get three darts in the outer ring.
