501 Darts Game

The 501 darts game is the standard format you?ll see in most televised and competitive darts, and it?s also one of the best ways to practise properly at home. It looks simple?start on 501, get to zero?but the detail matters: how you start, how you finish, and how you score can change the entire shape of a match. On DartsStats.com, we break down 501 in a way that?s practical for players, fans, and anyone who wants to understand match flow, momentum, and the numbers behind smart decisions.

What Is 501 Darts?

501 is a ?countdown? game. Each player (or team) begins a leg on 501 points. You take turns throwing three darts per visit, scoring points based on where the darts land. Your scored points are subtracted from your remaining total. The winner is the first to reach exactly zero under the finishing rules being used (most commonly double-out).

Why 501 is the benchmark

It rewards scoring power (high trebles, especially treble 20).
It tests finishing under pressure (doubles and checkouts).
It?s easy to follow yet deep enough for serious competition.

Objective of the Game

The objective is to reduce your score from 501 to exactly 0, before your opponent, following the chosen finishing rule (usually double-out). The key word is ?exactly?: if you score more than you have remaining (or leave 1 in double-out), you ?bust? and your visit does not count.

What skills 501 measures

Scoring efficiency: how quickly you can reach a finish.
Checkout ability: converting chances, especially from 60?120.
Pressure management: hitting a double when it matters.
Match play: choosing targets based on score and opponent position.

Players and Match Formats

501 can be played:

One vs one (the most common format).
Doubles (two players per team, alternating throws).
Teams (varies by league rules; usually alternating players each visit).

Typical match structures

Best of legs: e.g., best of 11 legs (first to 6).
Sets and legs: e.g., best of 5 sets, best of 5 legs per set.
Race to a number: e.g., first to 10 legs.

In most professional formats, there?s also an important concept called the throw (or ?throwing first?). Because doubles can be hard, the player throwing first in a leg often has a small advantage, especially when both players score similarly.

Starting and Finishing Rules

Most organised 501 uses:

Single-in: you can start scoring immediately on your first dart.
Double-out: you must finish on a double (including double bull in competitions that treat the bull as 25/50).

What ?double-out? means in practice

If you have 40 left, you can finish with D20 (double 20). If you have 32 left, D16 is a common route. If you have 50 left, some rules allow bull (50) as a double; many competitive formats do.

Bust rules (the most common)

You bust if, during a visit:

You reduce your score below zero, or
You leave a score of 1 in double-out, or
You hit zero without finishing on a double.

When you bust, your score resets to what it was at the start of that visit, and your turn ends immediately.

Scoring Explained

The dartboard has numbered segments 1?20. Each number has:

Single segment (worth face value)
Double ring (worth 2? face value)
Treble ring (worth 3? face value)

The centre has:

Outer bull (25)
Bullseye (50)

Examples of common scores

T20 = 60
20 + T20 + 20 = 100
T19 + T18 + D12 = 57 + 54 + 24 = 135 (scoring visit, not a finish)
Single bull = 25; bullseye = 50

Maximum and ?big? turns

180: three treble 20s (the maximum with three darts).
140: typically T20 + T20 + 20 (a strong scoring visit).
100: often used as a benchmark for solid, controlled scoring.

How a Leg Is Won

A leg ends when a player reaches exactly zero under the finishing rule. In double-out 501, that means the final dart must land in a double segment (or bull if treated as double).

Typical checkout routes (double-out)

170: T20, T20, bull (the highest possible checkout)
121: T20, 11, bull (one common route)
100: T20, D20 (or 20, D20, D20 depending on preference)
81: T19, D12 (or 19, 12, D25 in some styles)
40: D20 (classic ?tops? finish)

At a practical level, legs are often decided by who gets a ?clean look? at a finish first and then who converts it. That?s why the most valuable skill combination is heavy scoring plus reliable doubles.

Sets vs Legs Formats

Understanding the structure matters because it changes how pressure builds and how momentum swings.

Legs-only matches

In a legs-only format (e.g., first to 10 legs), every leg counts equally. A run of two or three legs can be decisive, and players often focus on holding throw and timing a break of throw.

Sets-and-legs matches

In a sets format, you must win a group of legs to take a set (commonly best of 5 legs). This can create ?mini matches? inside the overall contest:

You can lose a leg but still win the set.
Closing out a set can create an extra pressure point, similar to serving for a set in tennis.
Players may be more conservative if a set is secure, but aggressive when a set is on the line.

Common Variations

Although 501 double-out is the default in competitive darts, you?ll also see these variations in leagues, pubs, and practice.

Double-in / double-out

You must hit a double to ?start? scoring, and also finish on a double. This reduces random early scoring and puts more emphasis on doubling accuracy.

Single-out

You can finish on any segment. This makes finishing easier and typically shortens legs, which can suit casual play but reduces the importance of doubles.

301 / 701

301: faster legs; often used for quick matches or practice.
701: longer legs; can suit team formats and endurance-style play.

Handicapped 501

Players start on different totals (e.g., one player starts on 501, the other on 601), or one player begins closer to a finish. Handy for balancing mismatched ability in a friendly setting.

Competitive Strategy Basics

Good 501 is mostly about making your darts ?stack?: build high scores, leave sensible finishes, and avoid busting. Here are the fundamentals competitive players lean on.

1) Prioritise high-percentage scoring

The default scoring bed is T20. If T20 is blocked (a dart in the treble ring) or you?re missing into awkward areas, many players switch to T19 to keep scoring rhythm.

Strong scoring visits put pressure on your opponent?s finishing.
Even ?only? 100?120 regularly can outplay sporadic 140s and 60s.

2) Set up a finish you like

A big part of 501 is leaving a preferred double. Many players like:

D20 (40), D16 (32), D10 (20) for straight routes.
Avoiding awkward doubles such as D1 and D3 where possible.

That means sometimes scoring slightly less is correct if it leaves a better checkout.

3) Know your outs and ?bogey numbers?

In double-out, not every total is finishable in one visit of three darts. Totals like 169, 168, 166, 165, 163, 162, 159 are commonly called ?bogey numbers? (no standard three-dart checkout). Knowing them helps you plan ahead: aim to leave a finishable number after your next visit.

4) Manage bust risk

Busting doesn?t just waste darts; it hands initiative to your opponent. If you?re on a finish, think about:

Choosing a route that keeps you on a double even after a miss.
Avoiding going for low-percentage combinations if a safer setup exists.

5) Match play: react to the opponent?s position

When your opponent is waiting on a finish, ?setting up? isn?t enough?you often need to apply pressure by either taking the finish immediately or leaving a very strong chance next visit (for example, leaving 40 or 32).

Two concrete betting scenarios (with numbers)

501 is also a popular betting product because it?s measurable: legs, checkouts, and 180s. Here are two realistic scenarios that show how understanding the rules and match flow helps you read markets responsibly.

Scenario 1: Legs handicap in a race format

Match format: first to 10 legs (best of 19). A common line might be a -1.5 legs handicap on the favourite at 1/1 (evens) in fractional odds.

If you back the favourite -1.5, they must win by 2+ legs (e.g., 10?8, 10?7, 10?5).
Understanding 501 matters because holding throw is a big edge. If the favourite throws first and is a stronger double-out player, they?re more likely to convert ?first look? finishes and create a two-leg gap.
Example match state: after 8 legs it?s 5?3. The favourite is effectively ?on track? for a 10?7 style win, but a single break of throw can flip the handicap outcome quickly.

Scenario 2: Checkout-based prop tied to double-out rules

In double-out 501, a player can only finish on a double (or bull). Suppose there?s a market such as ?Player A to hit a 100+ checkout? priced at 5/2.

A 100+ checkout includes finishes like 100 (T20, D20) or 104 (T18, D25), 121 (T20, 11, bull), etc.
How 501 plays into it: if Player A regularly leaves totals between 100 and 130 (by scoring hard but not tidily), they may create more opportunities for a 100+ finish than a player who constantly leaves 40?60.
Concrete example: Player A reaches 121 twice in a match and takes it once (T20, 11, bull). That single moment lands the bet?so tracking a player?s typical leave patterns and bull confidence is more relevant than raw average alone.

These examples are not tips or promises?just illustrations of how rules, format, and scoring logic connect to the numbers you might see.

When 501 Is Used

501 is used across darts because it balances speed with skill. You?ll typically find it in:

Professional and televised events (commonly 501 double-out).
County and league darts throughout the UK.
Pub matches (often 501, sometimes single-out depending on house rules).
Serious practice routines because it mimics competitive pressure: scoring, setups, and doubles.

FAQs

Do you have to finish on a double in 501?: In most competitive formats, yes: 501 is played as double-out. Some casual games use single-out, so it?s always worth agreeing the rules before you start.
What happens if you ?bust? in 501?: If you bust (go below zero, leave 1 in double-out, or hit zero without a double), your entire visit is void. Your score returns to what it was at the start of that turn, and play passes to your opponent.
Can you finish 501 on the bullseye?: You can finish on the bullseye (50) if your rules treat it as a double (common in competitive play). For example, finishing 50 with a single dart on the bull is typically allowed.
What is the highest possible checkout in 501?: 170 is the highest three-dart checkout: T20, T20, bull. Anything higher cannot be finished in three darts under standard rules.
What does ?legs? and ?sets? mean?: A leg is one game of 501 from 501 down to zero. A set is a collection of legs (often best of 5). Matches can be legs-only or sets-and-legs depending on the competition.
What is a ?break of throw? in 501?: A break of throw is when a player wins a leg despite their opponent throwing first in that leg. Because throwing first can be an advantage, breaks are key momentum shifts.
Is 501 always the same in every league?: The basics are consistent, but leagues may vary on details such as single-out vs double-out, bull counting as double, throw order in doubles, and whether scores must be called. Check local rules to avoid disputes.

The Final Throw

501 is simple to start and endlessly challenging to master: score heavily, leave sensible finishes, and close legs by hitting doubles under pressure. If you understand the start and finish rules, bust conditions, and how legs and sets change match dynamics, you?ll read games far better?whether you?re playing, watching, or analysing results.

For match analysis, focus on the measurable levers: who holds throw most reliably, who converts first-dart doubles, and who consistently leaves makeable finishes rather than awkward totals. Those details explain why some players ?feel? stronger even when raw averages look close.

If you choose to bet, use the 501 framework to keep decisions grounded in evidence?format, scoring patterns, and checkout tendencies?rather than highlights or hunches. Always stake within your limits, avoid chasing losses, and treat betting as entertainment, not income.
