Bogey numbers: the scores you can't finish

Why these seven scores can't be finished

To check out, your three darts must sum to the score and the last one must be a double (max D20 = 40 or the 50 bull). The most you can score with two setup darts is two trebles (T20 + T20 = 120), leaving up to 50 for the finish.

For scores just under 170, the arithmetic simply doesn't line up with any valid double on the third dart — so these seven have no three-dart double-out, no matter how you throw them.

What to leave instead

If a visit would leave you on a bogey number, don't try to finish. Score down to a clean leave for your next turn — ideally 40 (D20) or 32 (D16). For example, on 168 a single 18 leaves 150, then a strong visit can set up 40.
