Darts Scoring for Beginners: 301, 501, and Double-Out Rules
A dart's landing area tells you its value. The remaining score and your chosen finish rule tell you what can happen next. Learn both, then put them together in a complete 301 game.
You have 40 points left. Your first dart lands in the large part of the 20 sector, scoring 20. Another 20 would bring the arithmetic to zero. But if you are playing double-out, that second single 20 would cancel the whole turn. You need double 10 instead.
That small situation captures the part of darts scoring that can feel confusing at first. Adding the darts is only one step. You also need to know what remains and which landing area can legally finish the game.
Start with the board, then work through a turn. The examples below use the 2026 Darts Regulation Authority rules as the named steel-tip reference, with a clearly chosen casual format for the complete game: 301, straight-in, double-out. The DRA's ordinary competition format is 501 with those opening and finishing conditions, unless an event specifies otherwise. Choosing 301 here brings the finishing practice closer without changing the scoring values.
Read the board before adding the score
A standard dartboard has 20 numbered sectors. Each sector contains two broad single-score areas and portions of two narrow scoring rings. The printed number identifies the sector; where the point lands within it determines the multiplier.
The 20 sector is at the top. Its neighbors are 5 and 1, so a dart close to your intended target can still produce a very different score. You do not need to memorize the whole board before playing. Begin by finding the number, then checking the ring.
| Landing area | How it scores | Example |
|---|---|---|
| Either broad single area in a numbered sector | The sector's number | Single 20 scores 20 |
| Outer narrow ring | Twice the sector's number | Double 20 scores 40 |
| Inner narrow ring | Three times the sector's number | Triple 20 scores 60 |
| Outer bull, the ring around the central circle | 25 points | Outer bull scores 25 |
| Inner bull, the central circle | 50 points | Inner bull scores 50 |
| Outside the outer double wire, or a non-scoring miss | Zero | A miss scores 0 |
The inner narrow ring is also called the treble ring. Triple and treble mean the same thing here. The broad area between the bull and treble ring scores a single, as does the broad area between the treble and double rings. Being nearer the center does not automatically make a dart more valuable.
These ring and bull values are specified in DRA Rules 2026, sections 6.5.3–6.5.7. The inner bull scores 50, not 100. Triple 20, at 60, is the highest score available with one dart.
Learn the shorthand as you use it
Score sheets often abbreviate single, double, and triple as S, D, and T. Thus S20 = 20, D20 = 40, and T20 = 60. Three darts landing in those areas would total 20 + 40 + 60 = 120.
Some scorers write a single as the number alone: 20 means the same as S20. This guide keeps the S to make examples easier to follow. It spells out outer bull and inner bull so the two values remain clear.
A double is a scoring area, not two darts hitting the same number. Double 10 is one dart in the outer narrow ring of the 10 sector, worth 20 points.
Count where the point meets the board
On a physical steel-tip board, look at the point's position. A dart's barrel or flight can lean across a wire while its point scores in a different area. Under the DRA rules, the scoring segment is determined by where the point enters and remains in or touches the board face within the outer double wire.
A dart that bounces off or falls out before retrieval scores nothing and cannot be thrown again. A dart caught in another dart without its point touching the scoring face also scores nothing. A deliberate throw that misses uses up one of your available darts. Accidentally dropping a dart before the deliberate throwing action begins is different: the DRA allows it to be picked up and used.
These physical scoring requirements come from DRA sections 6.2.4, 6.2.7, and 6.4.1–6.4.3. Electronic machines can register impacts differently; check their selected rules rather than applying every steel-tip procedure automatically.
Take a turn and record what remains
A turn, often called a visit, normally allows up to three darts thrown one at a time. After your visit, confirm and record the score, retrieve your darts, and let the next player take their turn.
A leg is one complete game from the starting score to a legal winning finish. Players can play a single leg or agree on a match made up of several legs.
The phrase “up to three darts” matters. Under the DRA rules, a visit ends early if you finish the leg, bust your score, or touch a dart already in the board during that visit. There is no spare throw after a win or bust. DRA section 6.2.6
Subtract the darts in order
In a countdown game, your score shows how many points you still need to remove. Suppose you begin on 501:
| Dart | Landing | Points | Remaining |
|---|---|---|---|
| 1 | T20 | 60 | 501 − 60 = 441 |
| 2 | S18 | 18 | 441 − 18 = 423 |
| 3 | S1 | 1 | 423 − 1 = 422 |
The visit total is 60 + 18 + 1 = 79. Your scorekeeper can check the result another way: 501 − 79 = 422.
When your turn comes around again, you start from 422. If you hit D16, S20, then miss, the sequence is 422 − 32 = 390, 390 − 20 = 370, then 370 − 0 = 370. That visit scores 52 and leaves 370. Your opponent's turns do not change your own remaining score.
Both bulls use the same subtraction. From 200, outer bull leaves 175, inner bull then leaves 125, and a final miss leaves 125. The total is 25 + 50 + 0 = 75; 200 − 75 = 125.
Early in a leg, adding the three darts and subtracting the total is usually convenient. Near a finish, update the remainder after each dart. A bust or winning double can end the visit before dart three.
Confirm the score before pulling the darts
In DRA play, darts are retrieved after the referee has called the score or the marker has recorded it. Scores and subtraction should be checked after each visit, preferably before the next player begins. A home game can have the opponent or thrower do the writing, but keep the same useful habit: settle the score while the darts are still visible.
Record the points scored and the new remainder. For the first example, that is 79 scored, 422 remaining. Keeping both makes an arithmetic mistake easier to find. Formal events have correction deadlines; a casual group should agree to check and resolve a discrepancy immediately. DRA sections 6.4.3–6.4.6
Choose the rules for 301 or 501
The names 301 and 501 tell you the starting total. Each player subtracts valid scores from that number, trying to reach exactly zero under the agreed finishing rule.
Starting at 301 removes 200 points of countdown compared with 501. It can get a casual group to the finishing stage sooner, though missed doubles can still make a leg last a while. There is no guaranteed beginner game length.
The starting number does not settle how a leg begins or ends. Those are separate choices:
| Term | Meaning |
|---|---|
| Straight-in | Valid scoring darts count from the beginning; no opening double is required. |
| Double-in | Nothing is deducted until you hit an opening double. That double itself counts, followed by subsequent scoring darts. |
| Straight-out | Any scoring area may finish, provided the score reaches exactly zero. |
| Double-out | The final scoring dart must be a double that brings the score to exactly zero. The inner bull can finish 50. |
For the main tutorial, agree on 301, straight-in, double-out. Every valid hit counts immediately, and a double must finish the leg. The DRA's general competition rule is 501, straight-in, double-out, subject to a particular event's published format. The casual 301 game here borrows those scoring and finishing mechanics; it is not presented as the DRA's default event format. DRA section 6.3.1
Double-in changes the opening
Suppose you choose the separate variation 301, double-in, double-out. Your first three darts are single 20, double 10, and single 5:
| Dart | Landing | Credited points | Remaining |
|---|---|---|---|
| 1 | S20, before opening double | 0 | 301 |
| 2 | D10, opening double | 20 | 281 |
| 3 | S5, now scoring normally | 5 | 276 |
The visit removes 25 points, leaving 301 − 25 = 276. The first single 20 is not deducted later. If you never hit an opening double during a visit, you remain on 301 and try again on your next turn.
Once you are in, you do not need another opening double on each visit. The requirement starts afresh with the next leg. A double-in requirement and a double-out requirement govern different moments in the game.
Double-start is used in the PDC's World Grand Prix. It is not mandatory in every game called 301. For the split-bull variation described here, the inner bull qualifies as a double, while outer bull does not; the NDA also explicitly permits double-bull entry in its specified Masters double-in/double-out events. That does not make all electronic formats identical to this tutorial.
Double-out changes the finish
A checkout is a legal route from your current remainder to zero within the darts still available in your visit. From 40, D20 is a one-dart checkout because it scores exactly 40 on a double.
From 50, inner bull can finish in one dart: the DRA treats it as double 25 for that finish. Outer bull scores 25 and cannot itself finish a double-out leg. DRA sections 6.3.1–6.3.3
You can still score doubles earlier in the leg. From 301 in straight-in play, D20 simply removes 40 and leaves 261. It does not end the leg because the remainder is not zero.
Understand exactly what a bust cancels
Under the selected double-out rules, a bust happens when a dart:
- Takes the remainder below zero.
- Leaves exactly one, which cannot be finished on a double.
- Reaches zero without the required double.
A bust ends the visit immediately. Credit zero points for the entire visit and restore the score you had before its first dart. Earlier successful darts in that same visit are cancelled too. Your next turn starts from that restored score. These are the conditions in DRA sections 6.3.3 and 6.2.6.3.
Bust 1: scoring more than remains
Start the visit on 40. S16 scores 16, temporarily leaving 24. Your second dart lands in T9, scoring 27: 24 − 27 = −3.
That is a bust on dart two. Dart three is not thrown. Record BUST, 0 credited, 40 remaining. You restore 40, not the intermediate 24, and certainly not the original 301.
Bust 2: leaving one
Start on 32. S16 leaves 16. S15 then scores 15 and leaves one.
The smallest double is D1, worth two, so one cannot be checked out under double-out rules. Stop after dart two and record BUST, 0 credited, 32 remaining. You cannot use dart three to try to repair the one.
Bust 3: reaching zero through the wrong area
Start on 40. S20 leaves 20. Another S20 produces zero, but the final dart is a single. Stop after dart two and record BUST, 0 credited, 40 remaining.
The same condition applies to T20 from 60: it scores 60 but reaches zero on a triple. That first dart busts the visit; credit zero and restore 60. Outer bull from 25 also busts: it reaches zero through a single-score area, so credit zero and restore 25.
A different finish rule changes the decision
For an explicitly agreed straight-out variation, use this definition: exact zero wins; going below zero busts and restores the beginning-of-visit score. Leaving one is allowed because S1 can finish. T20 from 60 and outer bull from 25 are then legal finishes.
That is a different finishing rule, not an exception you apply when a double becomes difficult. Choose it before the leg. Other house or electronic formats may make different choices, so establish their rules rather than carrying this tutorial's bust conditions into every game.
Find a finish you can understand
You do not need a large checkout chart to begin. Learn a few doubles and the small subtractions that leave them available.
The following routes assume enough darts remain to complete them. A two-dart route cannot be used when you have only one dart left.
| Remaining | Legal route | Remainders after successful darts |
|---|---|---|
| 16 | D8 | 16 − 16 = 0 |
| 20 | D10 | 20 − 20 = 0 |
| 24 | D12 | 24 − 24 = 0 |
| 32 | D16 | 32 − 32 = 0 |
| 40 | D20 | 40 − 40 = 0 |
| 50 | Inner bull | 50 − 50 = 0 |
| 50 | S10, D20 | 50 → 40 → 0 |
| 50 | S18, D16 | 50 → 32 → 0 |
| 60 | S20, D20 | 60 → 40 → 0 |
From 50, inner bull is the only one-dart checkout. With two or three darts available, S10–D20 gives you a broad single followed by an outer double. S18–D16 is another choice. Neither is automatically the best route for every beginner; familiarity with the targets matters.
From 60, avoid confusing the scoring target T20 with the finishing route S20–D20. Both total 60, but only the latter ends on a double.
Why 32 is a useful number to recognize
Suppose you aim at D16 from 32 and land just inside it in S16. You have scored 16 and left 16, which can be finished on D8. If the next dart lands in S8, eight remains, so D4 can still win with your third dart:
32 − 16 = 16; 16 − 8 = 8; 8 − 8 = 0.
Each landing changes your next target. You are not continuing to aim at D16 regardless of the score.
This arithmetic makes 32 a useful practice remainder. It does not prove D16 is everyone's easiest double, and the recovery depends on where the darts actually land. An outside miss scores zero; a dart in another numbered sector needs a fresh calculation.
Recalculate after an unexpected landing
Start on 32 and aim at D16, but suppose your dart lands in S8. That scores eight, leaving 24. With another dart available, D12 can finish: 32 − 8 = 24, then 24 − 24 = 0.
From 50, suppose an attempted inner bull instead lands in outer bull. Twenty-five remains, and you still have two darts. S9 can leave 16, followed by D8:
50 − 25 = 25; 25 − 9 = 16; 16 − 16 = 0.
That is a possible recovery, not a guarantee. If you hit outer bull again from 25, the visit busts and restores the original 50. If your first dart misses the scoring area entirely, 50 remains with two darts available, so S10–D20 is still a possible route.
A complete finish from 72
With all three darts available, you can finish 72 without a treble:
| Dart | Landing | Points | Remaining |
|---|---|---|---|
| 1 | S20 | 20 | 52 |
| 2 | S20 | 20 | 32 |
| 3 | D16 | 32 | 0 — legal checkout |
The total is 20 + 20 + 32 = 72. If either single lands elsewhere, stop following the memorized route and calculate the actual remainder.
For context, the highest three-dart double-out checkout is 170: T20, T20, inner bull, totaling 60 + 60 + 50. The first two darts cannot exceed 60 each, and 50 is the largest legal finishing double. That is a demanding three-dart finish; the smaller examples above are enough to start learning the process.
Play and score a complete casual 301 leg
Maya and Noah want to practise subtraction and finishing without adding tournament administration. Here is their complete agreed format:
- Two players, each starting on 301.
- Straight-in: every valid scoring hit counts immediately.
- Double-out: exact zero on an outer double or the 50-point inner bull wins.
- Up to three darts per visit, alternating between players.
- DRA-style busts: stop immediately, credit zero, and restore the visit's starting score.
- Steel-tip misses, bounce-outs, and fall-outs before retrieval score zero with no rethrow.
- A coin toss chooses the starter for this casual leg. Maya wins it and starts.
- The waiting player records the score; both check it before the thrower retrieves the darts.
The coin toss is a house arrangement. The DRA recommends a throw at the bull for determining order, subject to the event's rules. Their scoring arrangement also permits friendly help with calculations; formal DRA officials may state the amount scored or required but may not advise how to finish. DRA sections 6.13.1–6.13.2 and 6.15.6
For a physical steel-tip setup, the DRA reference places the bull center 1.73 m above floor level and the throwing position 2.37 m horizontally from the board face. Measure from the face, not the wall behind it. Use a clear throwing area, and wait until the previous player has retrieved the darts and moved clear before throwing. The regulation setup is described in DRA sections 6.5.9 and 6.7.
Maya's score sheet
These two sheets describe one interleaved game: Maya's first visit, Noah's first visit, Maya's second, Noah's second, and so on. They are fictional teaching examples, not predicted beginner performance.
| Visit | Starts on | Darts in order | Credited points | Remaining |
|---|---|---|---|---|
| 1 | 301 | S20, S5, S19 | 44 | 257 |
| 2 | 257 | S20, T19, miss | 77 | 180 |
| 3 | 180 | S18, S20, S5 | 43 | 137 |
| 4 | 137 | S20, S1, S16 | 37 | 100 |
| 5 | 100 | S20, S20, S20 | 60 | 40 |
| 6 | 40 | Miss, S20, miss | 20 | 20 |
| 7 | 20 | S10, S9 — bust on dart 2 | 0 | 20 |
| 8 | 20 | Miss, D10 — checkout on dart 2 | 20 | 0 |
Her opening visit scores 20 + 5 + 19 = 44, leaving 301 − 44 = 257. Visit two scores 20 + 57 + 0 = 77, leaving 180. The next two totals, 43 and 37, bring her through 137 to 100.
Visit five removes 60 through three single 20s and leaves 40. This is legal: her last single leaves a positive remainder, so she has not attempted an invalid finish. In visit six, a miss leaves 40, S20 leaves 20, and the final miss leaves 20 for her next visit.
Visit seven shows why the starting-score column matters. S10 leaves 10; S9 then leaves one and busts. Credit zero, copy the starting 20 into the remaining column, and leave dart three unthrown.
On visit eight, the first dart misses and the second hits D10 for 20. Maya reaches zero on a double and wins. Her third dart is unused. Her credited points across the leg are 44 + 77 + 43 + 37 + 60 + 20 + 0 + 20 = 301.
Noah's score sheet
| Visit | Starts on | Darts in order | Credited points | Remaining |
|---|---|---|---|---|
| 1 | 301 | S19, S7, miss | 26 | 275 |
| 2 | 275 | S20, S20, S1 | 41 | 234 |
| 3 | 234 | S19, T19, S3 | 79 | 155 |
| 4 | 155 | S20, S5, S20 | 45 | 110 |
| 5 | 110 | S20, S18, S12 | 50 | 60 |
| 6 | 60 | S20, miss, S20 | 40 | 20 |
| 7 | 20 | Miss, S10, miss | 10 | 10 |
Noah's third visit totals 19 + 57 + 3 = 79; 234 − 79 = 155. His fifth removes 20 + 18 + 12 = 50, leaving 60. On visit six, the two single 20s leave 20, so that visit is valid too.
He finishes his seventh visit on 10. Maya then checks out before he gets another turn. There is no equalizing visit: the leg ends when the first player achieves the required finish. Noah has scored 26 + 41 + 79 + 45 + 50 + 40 + 10 = 291, leaving 301 − 291 = 10.
To play again, restore both starting scores to 301, keep the same scoring rules, and let Noah start the rematch under their agreed alternating-start arrangement. If time runs out before a checkout, record the leg as unfinished rather than quietly treating the lowest remainder as a legal double-out win.
Practise scoring and doubles together
For a beginner, a useful practice session has an understandable task and a record of what actually happened. You can learn something from a miss if you know the intended target, the landing area, and the next remainder.
Coaching guidance commonly combines repeated doubles practice with finishing exercises. Winmau's discussion of doubles training distinguishes those tasks and labels its demanding Double Doubles game as more suitable for advanced players. The routine below uses a simpler original format.
Try this 15-visit routine
Use a physical board, three darts, and paper or a scorekeeper. The routine takes at most 45 darts; checkout attempts can end early. There is no required completion time.
| Block | Five assigned targets or starting scores | What to do |
|---|---|---|
| 1: Broad singles | S20, S19, S16, S20, S16 | Take one three-dart visit at each target. Aim for the broad single area and record all actual landings. |
| 2: Doubles | D16, D8, D20, D10, D12 | Take one three-dart visit at each double. Count intended-double hits and record actual scores separately. |
| 3: Checkouts | 16, 24, 32, 40, 60 | Start a separate double-out attempt from each number. Allow up to three darts; stop at a checkout or bust. |
In the first two blocks, the assigned target stays the same for all three darts of that visit. These are target drills, not countdown legs. A first-dart double in block two is one target hit, so you still have two practice throws. There is no countdown score to bust.
If you aim for S20 and hit D20 in block one, record 40 points but no intended-single hit. That distinction stops a high score from hiding a missed target. Review where the darts grouped as well as the points they produced.
Block three changes the task. From 32, hitting D16 ends that attempt immediately; do not throw the other darts as part of it. Hitting S16 then S15 busts: record zero credited points and a restored remainder of 32, then end the attempt. For the next exercise, reset to its assigned starting score, 40.
If three darts leave a positive legal remainder, record it as an unfinished attempt. Do not carry it into the next assigned number. This reset is part of the drill, not a competitive game rule.
A useful recording row contains target or starting score, dart landings, target hits or credited points, final remainder where relevant, and one observation. For example: “32; S16, S8, D4; 32 credited; zero; recovered after two inside singles.”
Review each five-visit block before changing anything. Repeat the same routine on another occasion if you want a comparison. A more consistent grouping, fewer arithmetic corrections, or a correctly recognized bust can each be worth noticing without claiming that one session proves lasting improvement.
Keep the advice proportionate to the evidence
Try a comfortable, repeatable setup and a clear target. You might find a simple cue about the intended landing point helpful. Avoid assuming there is one required thought pattern: a 2026 systematic review of attentional focus in dart throwing found mixed, context-dependent results, with limited transfer evidence.
Start with a task you can understand and tolerate repeating. That is a practical choice, not a promise of faster learning. In a dart-throwing target-size experiment, easier targets increased perceived success during practice without producing superior delayed retention. Neither study validates this complete routine or establishes an optimal number of practice minutes.
Without a board, you can use a printed diagram and the example sequences to practise identifying scores, subtracting, and naming a legal next target. That rehearses scoring decisions; physical throwing still needs physical practice.
Know what changes on a screen
A browser scorekeeper and a browser darts game do different jobs. With a scorekeeper, you throw real darts and enter their scores. The software can handle subtraction, but you still practise the physical aim and release. Predicting the remainder before entering the score keeps some mental arithmetic in the session.
A simulation substitutes controls such as clicking, dragging, or stopping a moving marker. It may let you rehearse board recognition and checkout decisions if its rules match the format you are learning. Its aiming task, simulated misses, and outcome patterns belong to that particular game; they do not establish your accuracy with real darts.
One study of VR dart training found worse subsequent real-world accuracy in its VR-trained group, with limitations involving the simulated task and controller. That does not show that every browser game harms throwing. It gives a reason to be careful about assuming that performance transfers between different control tasks.
Before using a browser darts activity for scoring practice, check its available rules against the chosen 301 or 501 format. Aiming with a screen control is a separate task from practising a physical release. The worked scoring examples here define their own rules and do not certify a particular application's countdown or double-in implementation.
Electronic physical boards also need their own rule check. For example, the NDA's rules specify a full 50-point bull for open-in/open-out play and a 25/50 split bull for its stated Masters double-in/double-out events. Machine scoring procedures differ from steel-tip retrieval rules. Check the event or machine settings before using a bull value or finish rule from another format.
Keep this reference beside the board
For the casual game taught here: 301, straight-in, double-out; outer bull 25, inner bull 50; up to three darts; whole-visit bust restoration. Standard DRA competition starts from 501 unless the event specifies otherwise.
Scores and useful finishes
| Read or need | Meaning or route |
|---|---|
| S followed by a number | Single: that number in points |
| D followed by a number | Double: twice that number |
| T followed by a number | Triple/treble: three times that number |
| Outer bull / inner bull / miss | 25 / 50 / 0 |
| 16 / 20 / 24 remaining | D8 / D10 / D12 |
| 32 / 40 remaining | D16 / D20 |
| 50 remaining | Inner bull, or S10 then D20 with at least two darts |
| 60 remaining | S20 then D20 with at least two darts |
Before the next player throws
- Note the score at the beginning of the visit.
- Read each landing area and subtract in order, especially near a finish.
- Stop on a legal checkout or on a bust. Never count extra darts after either.
- For a valid ordinary visit, record its total and subtract it from the starting score. For a checkout, record zero remaining.
- For a bust, record zero credited points and copy the beginning-of-visit score unchanged.
- Confirm the result while the darts are visible, retrieve them, and let the next player begin once the area is clear.
The three double-out bust checks are below zero, one remaining, or zero without a double. Missing an intended target is not itself a bust; the actual score and finish condition decide.
A winning double needs to remain a valid scoring dart under the physical rules. The DRA allows a score or game-shot call to be revoked if darts fall before retrieval, so wait for confirmation and collect the darts normally. DRA sections 6.3.9–6.3.11
You can pause before a throw to work out what remains. Once you can read the area, subtract its value, and recognize the required finish, you have a practical way through the next turn.
