104 checkout

In short

104 checks out in two darts under double out: T18, BULL, for 54 + 50. If the treble 18 lands in the single 18, 86 is left and still on: T18, D16. Should the second dart, at the bull, drop into the outer bull, 25 is left, out of reach with the last dart: S9 leaves 16, so D8 on the next visit. With a single dart in hand, T18 leaves 50, so BULL.

When a dart strays

A missed treble or double often drops into the single of the same segment, and a missed bull into the 25 around it. Here is what that leaves, and what comes next.
