81 checkout

In short

81 checks out in two darts under double out: T19, D12, for 57 + 24. If the treble 19 lands in the single 19, 62 is left and still on: T18, D4. Should the second dart, at the double 12, drop into the single 12, 12 is left and still on: D6. With a single dart in hand, T19 leaves 24, so D12.

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.
