129 checkout

In short

129 checks out in three darts under double out: T20, T15, D12, for 60 + 45 + 24. If the treble 20 lands in the single 20, 109 is left, out of reach with two darts left: T20, S17 leave 32, so D16 on the next visit. Should the second dart, at the treble 15, drop into the single 15, 54 is left, out of reach with the last dart: S14 leaves 40, so D20 on the next visit. With only two darts in hand, T20, T15 leave 24, so D12. Under straight out, where any segment can finish: T20, T20, S9.

Double out

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.

treble 20 → single 20

109 left, set up 32, so D16 on the next visit

T20

S17

treble 15 → single 15

54 left, set up 40, so D20 on the next visit

S14

double 12 → single 12

12 left, on the next visit

With fewer darts in hand

The finish is then out of reach: these darts set up the next visit.
