How to Avoid 166 in Darts
166 is a bogey number. Two treble 20s leave 46, which isn't a double. Every three-dart combination to 166 leaves a non-double remainder.
Bogey number — cannot be finished in three darts
Why 166 Is a Bogey Number
A bogey number is any score under 170 that cannot be taken out in three darts. 166 is one of seven such numbers. Here is why:
T20 (60) + T20 (60) = 120, leaving 46. 46 would need D23 — which doesn't exist.
T20 (60) + T19 (57) = 117, leaving 49. 49 is not a double.
T19 (57) + T19 (57) = 114, leaving 52. 52 needs at least two darts (20 + D16) — not possible with one remaining.
The Setup Shot: Leave 167 Instead
Instead of leaving 166, you should have left 167 on your previous visit. Here is the route:
167 checkout
T20 + T19 + bullseye
How to Avoid Landing on 166
Leave 167 or 164 on your previous visit. The key is knowing your out shot table before you step up. Dartsva's training plans include board management drills that train you to think one visit ahead.
Stop Leaving Bogey Numbers
Improve your board management with structured training plans. Dartsva tracks every dart, measures your checkout efficiency, and builds a training plan that fixes exactly what you get wrong.
