Reference · double-out · 2 to 170

Every checkout,
ranked and complete.

The standard route for every double-out finish from 2 to 170 — plus every other legal way to get there, not just the textbook one. Seven scores can't be finished in three darts at all: they're marked below.

Enter what you've scored so far in the leg — this works out what's left and how to finish it.
Works for any number 2–170. Try 170, 121, or 100.

How this chart is built

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.
