How to Avoid 163 in Darts

163 is a bogey number. Two treble 20s leave 43 — not a double. No three-dart combination reaches a finish from 163.

Bogey number — cannot be finished in three darts

A bogey number is any score under 170 that cannot be taken out in three darts. 163 is one of seven such numbers. Here is why:

T20 (60) + T20 (60) = 120, leaving 43. 43 is not a double.
T20 (60) + T19 (57) = 117, leaving 46. D23 doesn't exist.
T19 (57) + T19 (57) = 114, leaving 49. 49 is not a double.

Instead of leaving 163, you should have left 164 on your previous visit. Here is the route:

164 checkout

T20 + T18 + bullseye

Leave 164 instead. That means your last scoring dart on the previous visit should leave 164 — a valid three-dart finish via T20, T18, bullseye. One less treble, but a live out instead of a dead score.
