31 checkout

In short

31 checks out in two darts under double out: S15, D8, for 15 + 16. If the double 8 lands in the single 8, 8 is left and still on: D4. And if the double 4 drops into the single 4 as well, 4 is left for the next visit: D2. With a single dart in hand, S15 leaves 16, so D8. Under straight out, where any segment can finish: S20, S11.

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.
