115 checkout
In short
115 checks out in three darts under double out: T20, S15, D20, for 60 + 15 + 40. If the treble 20 lands in the single 20, 95 is left and still on: T19, D19. Should the third dart, at the double 20, drop into the single 20, 20 is left for the next visit: D10. With only two darts in hand, T20, S15 leave 40, so D20. Under straight out, where any segment can finish: T20, T15, S10.

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.
