142 checkout
In short
142 checks out in three darts under double out: T20, T14, D20, for 60 + 42 + 40. If the treble 20 lands in the single 20, 122 is left, out of reach with two darts left: T20, T14 leave 20, so D10 on the next visit. Should the second dart, at the treble 14, drop into the single 14, 68 is left, out of reach with the last dart: T16 leaves 20, so D10 on the next visit. With only two darts in hand, T20, T14 leave 40, so D20.

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.
