All legal three-dart double-out routes, ranked by convention. Anything here closes the leg.
Every route here is generated, not hand-picked. A search runs across all 62 dart values — 20 numbers each with single, double and treble, plus 25 and bull — and keeps every combination of one, two or three darts that lands exactly on the target with the last dart on a double or the bull, since that's the only way to legally end a double-out leg.
The top three shown for each score are the routes most players would actually throw: trebles preferred over doubles as setup darts, and finishing doubles ranked by how forgiving they are — 40, 32 and 16 rank highest because a missed dart still leaves a workable number, while finishes through bull rank lower because bull itself is a small, high-variance target. That ranking is a convention, not a rule. Every other legal route is one tap away for anything the top three don't cover — including finishes some players prefer specifically because they avoid a treble they don't trust, or route two darts through a double instead of one.
Seven scores between 2 and 170 have no legal three-dart finish under double-out: 159, 162, 163, 165, 166, 168 and 169. Land on one of these and the next dart has to change your position rather than finish the leg — that's the moment checkout suggestions matter most, since knowing which number to leave yourself is the difference between finishing next visit and stalling on a bogey number again.
