124 checkout

In short

124 checks out in three darts under double out: T20, T16, D8, for 60 + 48 + 16. If the treble 20 lands in the single 20, 104 is left and still on: T18, BULL. Should the second dart, at the treble 16, drop into the single 16, 48 is left, out of reach with the last dart: S16 leaves 32, so D16 on the next visit. With only two darts in hand, T20, T16 leave 16, so D8. Under straight out, where any segment can finish: T20, T18, 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.
