Can you go past zero in darts?

Mar 27, 202311 min read

Short answer: no, you cannot go past zero and win in standard 501 or 301 darts. If your visit takes you below zero, leaves exactly 1, or reaches zero without the required finishing double or bull, you bust. In the common rule set, your score returns to what it was at the start of that visit and your turn ends.

Last reviewed: 23 August 2026. This guide assumes standard x01 double-out darts. Pub, league, soft-tip and house formats can use straight-out or master-out variations, so confirm the format before a match.

The core rule

In x01 darts, the aim is to reduce your score to exactly zero. Under double-out rules, the final dart must land in a double segment or the bull. PDC Europe states that a leg must be finished with a hit in a double ring, including the bullseye. Darts501 also describes the standard x01 objective as reducing the score to exactly zero with the last dart hitting a double segment or bullseye.

That means zero is a threshold, not a zone you can pass through. More is not better at the end of a leg. The right amount, on the right segment, is what matters.

What counts as a bust?

A visit is bust if a dart leaves you below zero. It is also bust if it leaves exactly 1 in double-out, because there is no legal double worth one point. It is also bust if you reach zero without the final dart being a double or bull.

Dartshopper and Dartist both summarise the same practical rule: below zero, leaving one, or reaching zero without a double causes a bust, and the score reverts to the start of the turn. Net World Sports gives the same beginner-friendly explanation for x01 scoring.

What happens to the darts you already threw?

In the common rule set, the whole visit is cancelled. If you start on 32, hit single 16, then accidentally hit treble 8, you do not keep the single 16. The visit is bust, the turn ends, and your next visit starts from 32 again.

This is the part beginners often miss. Busting does not rewind only the final dart. It normally rewinds the visit. That makes route planning important because one careless dart can waste a useful setup dart.

Common bust examples

Score left	Dart or visit	Outcome
40	D20	Game shot.
40	S20, S20	Bust: zero without a double.
32	T20	Bust: below zero.
2	S1	Bust: leaves 1.
25	Outer bull	Bust in double-out: zero without double bull.
50	Inner bull	Game shot.

Why leaving 1 is a bust

Leaving 1 is impossible in double-out because no double scores one. The smallest double is double 1, which scores 2. If a dart leaves you with 1 remaining, the visit is treated as bust because you cannot finish from there under the format.

This is why double 1 is often called a painful finish. If you have 2 left and hit single 1, you have not left yourself one for the next visit. You have bust and return to 2.

Why zero without a double fails

Reaching zero is not enough in double-out. If you have 20 left and hit single 20, you have reached zero with the wrong segment. If you have 25 left and hit outer bull, you have also reached zero with the wrong segment. The legal finishing bull is the inner bull, worth 50.

This distinction matters because many casual players remember “get to zero” but forget “with the correct final dart”. In double-out darts, the final dart is the rule check.

What about straight-out and master-out?

Some casual formats use straight-out, where any scoring segment can finish the leg exactly. Some soft-tip or house formats use master-out, where a double, treble or bull may finish. These variations change what counts as a legal zero.

The article answer is still no: you do not go past zero and continue. But the “zero wrong” category depends on the finish rule. In straight-out, single 20 from 20 may be legal. In double-out, it is bust.

Checkout planning prevents most busts

Busts often happen before the final dart. They start with unclear planning. If you have 62 left, you should know what your first dart is trying to leave. If you have 41 left, you should know whether your route is single 9 for double 16, single 1 for tops, or something else based on your preferred doubles.

Good players work backwards from doubles they trust. They do not simply subtract whatever they hit and hope the next number is friendly. If you like double 16, you will often choose routes that leave 32. If you like tops, you will shape the visit towards 40.

Safer routes for awkward numbers

When the score is awkward, the safest route may not be the most aggressive route. From 62, many players go treble 10 for double 16 or single 10 to leave 52, depending on ability and preference. From 41, single 9 leaves 32, while single 1 leaves 40. The right route depends on which single you trust and which double you want.

The point is not that one route is perfect for everyone. The point is to choose before you throw. Unplanned darts near the finish create avoidable busts.

Worked match examples

Example one: 32 left. You are aiming at double 16. If you hit single 16, you have 16 left and can move to double 8. If you hit treble 16, you score 48 and bust. The target area is the same number, but the ring changes the result completely.

Example two: 40 left. Tops wins the leg. A single 20 leaves 20, so the next sensible target is double 10. Another single 20 reaches zero with the wrong segment and busts in double-out. That is why the second dart needs a fresh decision, not an automatic repeat.

Example three: 25 left. Outer bull looks tempting because it scores 25, but it does not finish a double-out leg. A safer plan may be single 9 to leave double 8, single 1 to leave double 12, or another setup based on the double you prefer. The best choice is the one you can repeat under pressure.

How bust rules affect pressure

Bust rules make the end of a leg feel different from normal scoring. Earlier in the leg, a stray treble may still be useful. Near zero, the same stray treble can cancel the visit. The board has not changed, but the consequence has.

This is why players slow down on finishing visits. They check the score, name the target, and know the recovery if the dart lands inside or outside. Rushing on 32, 40 or 24 causes avoidable busts because the player is still throwing as if they are scoring in the middle of the leg.

The pressure is also tactical. If your opponent is waiting on a finish, a bust gives them the board back without making progress. Even if you were one dart away from winning, the scoreboard may return to the start of the visit. That can turn a strong position into a lost leg.

Preferred doubles and recovery paths

Many players prefer double 16 because the recovery chain is friendly: 32, 16, 8, 4, 2. Missing inside often leaves another even double. Tops is also popular because 40 feels clean and familiar, but the recovery after a single 20 asks you to switch to double 10.

Double 12, double 8 and double 4 are useful because they create simple halving paths. Double 1 is more awkward because a single 1 busts from 2. This is why players try to avoid drifting down to the madhouse unless they have to.

Building a finishing plan around preferred doubles reduces mental load. Instead of solving every checkout from scratch, you learn a few reliable routes that keep you away from 1 and away from zero without a double.

How to practise avoiding busts

Use a “no careless bust” drill. Start from 61 and give yourself three darts. Your goal is either to finish legally or leave a clean double without busting. Repeat from 62, 63, 64 and 65. Write down whether the first dart gave you a sensible route.

Then practise common doubles in chains: 40, 32, 24, 16, 8 and 4. These routes teach recovery. If you miss inside or outside, you learn what the next dart leaves before pressure makes the decision for you.

For a sharper version, play against an imaginary opponent left on 40. Every bust loses the leg. Every clean finish wins it. Every sensible setup gets one more visit. This creates realistic pressure without needing another player.

Common beginner mistakes

Counting a bust dart: in the common rule set, the whole visit is cancelled.
Trying to finish on a single: this only works if the format is straight-out.
Forgetting that 1 is dead: leaving 1 is bust in double-out.
Throwing before choosing a route: the maths should be done before the arm starts moving.
Assuming every venue plays the same rules: house formats can differ.

Equipment and setup notes

Finishing practice needs clear doubles and reliable feedback. If the double ring is damaged, bounce-outs are common, or your darts are not grouping consistently, the practice becomes harder to judge. Browse dartboards for a cleaner scoring surface, dart sets if you are refining your setup, and darts accessories for flights, stems, mats and checkout practice essentials.

Why bust rules change behaviour

The bust rule makes late-leg darts more strategic because a player must control both ambition and risk. On a high score, an aggressive visit makes sense. Near zero, the wrong single can be as damaging as a missed double because it ends the visit and restores the previous score. That pressure is central to double-out darts.

Bottom line

You cannot go past zero in standard x01 darts. You must reach exactly zero, and in double-out the final dart must be a double or bull. If you go below zero, leave 1, or reach zero the wrong way, the visit is bust and your score normally returns to the start-of-turn total.
