111 checkout
111 checks out in three darts under double out: T20, S19, D16, for 60 + 19 + 32. If the treble 20 lands in the single 20, 91 is left and still on: T17, D20. Should the third dart, at the double 16, drop into the single 16, 16 is left for the next visit: D8. With only two darts in hand, T20, S19 leave 32, so D16. Under straight out, where any segment can finish: T20, T17. Under master out, where a treble can finish: T20, T17.
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.
With fewer darts in hand
The finish is then out of reach: these darts set up the next visit.
