Darts in hand
- With three darts: single 1, double 1.
- With two darts: single 1, double 1.
- With one dart only doubles and the bull finish, and 3 is not one of them.
The finishing double
The route finishes on double 1. 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
There is only one way to finish 3 with three darts.
