100 checkout
In short
100 checks out in two darts under double out: T20, D20, for 60 + 40. If the treble 20 lands in the single 20, 80 is left and still on: T20, D10. Should the second dart, at the double 20, drop into the single 20, 20 is left and still on: D10. With a single dart in hand, T20 leaves 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.
