What Is a Nine-Dart Finish? | Oche

The nine-dart finish is darts at its most perfect: a leg of 501 closed out in the minimum nine darts. It’s the sport’s holy grail — the equivalent of a 147 break in snooker or a perfect game in bowling — and seeing one live is a moment players and fans never forget.

The math behind the “perfect leg”

A standard leg starts at 501 and must end on a double. Nine darts is the fewest possible because you need enough scoring power to clear 501 and still land a finishing double. The arithmetic is tight: nine darts give you a maximum of 9 × 60 = 540 points, but you must hit exactly 501 ending on a double — so there’s no room for a single wasted dart.

That’s the whole appeal: zero margin for error across nine throws.

The classic route: seven maximums plus a finish

The most-used nine-darter line is seven treble 20s (7 × 60 = 420) followed by a two-dart finish on the leftover 81:

1. T20, T20, T20 → 321 left
2. T20, T20, T20 → 141 left
3. T20, T19, D12 → finish (60 + 57 + 24 = 141)

That last visit — T20, T19, D12 — is the textbook close. There are other valid routes (for example using the bull), but this “straight” nine is by far the most common on stage. Our nine-darter page lays out the alternatives.

Why it’s so rare

Every dart has to be near-perfect:

• The trebles must land in a treble bed barely larger than a fingernail, seven or eight times running.
• The finish has to be flawless — one missed double and the perfect leg is gone, no matter how good the first eight darts were.
• The rhythm can’t break. Pressure builds with every dart as the crowd realises what’s on.

Even the best players in the world average a handful of nine-darters across thousands of competitive legs. For club players, it’s a once-in-a-lifetime achievement.

Chasing your own perfect leg

You can’t force a nine-darter, but you can build the components: a reliable treble 20 and a clean T20, T19, D12 finish. Drilling those is exactly the practice that wins ordinary legs too — the perfect leg is just the same shots, strung together flawlessly. The full rules of the format are on our 501 rules page.

The Oche X01 scorer tracks every leg you play, counts your darts, and logs your treble and double hit rates — so you can see your best legs, watch your dart-count drop, and know the day you ever give the nine a real run.
