How to calculate
Enumerate standard scoring-bed routes in throw order and require a double or inner bull as the final dart.
Sum of scoring beds=remaining score; final bed∈{D1…D20,inner bull 50}
Worked example
Remaining 170 can finish in three darts as T20, T20, inner bull 50. Remaining 169 has no checkout in three darts, while 40 can finish in one as D20.
Assumptions and input details
Whole remaining score 2–170 and 1–3 available darts. Outer bull counts 25 and inner bull counts 50/double 25. Only shortest successful ordered routes are returned, with up to 100 shown and total route count disclosed. No misses, probabilities, target preferences, prior-turn bust recovery or entry-double variants are modeled. This is scoring arithmetic rather than a strategy recommendation.
