Darts in hand
- With three darts: double 13.
- With two darts: double 13.
- With one dart: double 13.
If the first dart misses
The only dart is the double itself. Drop into the single 13 and 13 is left over — that is an odd number that needs two darts.
The finishing double
The route finishes on double 13. An odd double does not halve: a single leaves an odd number that needs a single and a double, so it costs at least one extra dart.
Other ways out
These routes add up too. Players pick between them by the trebles they trust and the double they like to finish on.
