7 checkout
In short
7 checks out in two darts under double out: S3, D2, for 3 + 4. If the double 2 lands in the single 2, 2 is left and still on: D1. And if the double 1 drops into the single 1 as well, 1 is left: bust, the visit is lost. With a single dart in hand, S3 leaves 4, so D2. Under straight out, where any segment can finish: S7.

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.
