150 checkout
In short
150 checks out in three darts under double out: T20, T18, D18, for 60 + 54 + 36. If the treble 20 lands in the single 20, 130 is left, out of reach with two darts left: T20, T18 leave 16, so D8 on the next visit. Should the second dart, at the treble 18, drop into the single 18, 72 is left, out of reach with the last dart: T16 leaves 24, so D12 on the next visit. With only two darts in hand, T20, T18 leave 36, so D18.

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.
