9 checkout

In short

9 checks out in two darts under double out: S1, D4, for 1 + 8. If the double 4 lands in the single 4, 4 is left and still on: D2. And if the double 2 drops into the single 2 as well, 2 is left for the next visit: D1. With a single dart in hand, S1 leaves 8, so D4. Under straight out, where any segment can finish: S9. Under master out, where a treble can finish: T3.

Double out

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.

double 4 → single 4

4 left, with the last dart

With fewer darts in hand
