Darts Terminology and Slang Explained

Darts has a language of its own. Commentary can move quickly from a “ton 80” to a “bust”, while players talk about beds, checkouts and the madhouse as if everyone already knows what they mean. This guide explains the most common darts terminology and slang in clear, practical English, so beginners and casual spectators can follow a game with confidence.

Scoring terms you will hear most often

A ton is a score of 100 in one visit, usually made with three darts. The phrase ton 80 means a score of 180, the highest possible score from three darts on a standard board: each dart has hit the treble 20, worth 60 points. You may also hear 180 called a maximum. “Maximum” is the more general scoring description, while “ton 80” is one of the best-known pieces of darts slang.

The word visit, or throw, means a player’s turn at the board. In the usual format, the player throws up to three darts before the score is recorded and the turn passes to the opponent. A visit can contain one, two or three darts if the player completes the leg before all three are used, or if a rules situation ends the turn early.

A leg is one individual game, commonly played from a starting score such as 501 down to zero. A set is a larger match unit made up of a specified number of legs. The exact number of legs in a set depends on the competition format, so these terms should not be treated as interchangeable. For a broader grounding in how scoring and turns work, see darts rules and scoring.

Understanding the dartboard vocabulary

A bed is the scoring segment or area occupied by a dart. Players and commentators may refer to the single, treble or double bed for a particular number. For example, a dart in the treble 20 bed scores 60, while a dart in the double 20 bed scores 40. In everyday speech, “bed” can describe the target area rather than a separate scoring ring, so the surrounding context matters.

The single area scores the number printed on that section. The treble, also called the triple, is the narrow inner ring and scores three times the number. The double is the narrow outer ring and scores twice the number. The outermost centre area is the bull, or bullseye. Its precise scoring value and the way it can be used to finish may vary by ruleset, so beginners should check the rules being played rather than assume every format treats the bull identically.

The oche is the throwing line or marked distance behind which the player stands. A dart that lands outside the intended scoring section may hit the wire, meaning the metal boundary between scoring areas, or simply miss the board. A marker is a dart already in the board that helps a player judge the line or position for a later dart. A cover shot is a scoring attempt aimed at another useful target when the preferred target is blocked or difficult to reach.

Checkout terminology: finishing a leg

A checkout is the sequence that reduces a player’s remaining score to exactly zero under the rules in use. The score required to finish is often called the finish or the checkout itself. To take out a score means to complete that finish successfully. For example, if a player has 40 remaining and hits double 20, they have taken out the leg.

Double-out means the final dart must land in a double bed, with the bull commonly treated as a finishing double in formats that allow it. This is not universal across every form of darts: some games use different finishing requirements. When people discuss a checkout route, they are usually describing the scores a player is trying to hit in sequence, not a single mandatory path.

A bust occurs when a visit fails to produce a legal finish under the applicable rules. The most familiar example is scoring more than the remaining total. A bust can also occur when a player reaches zero without meeting a double-out requirement, or leaves an invalid score in a ruleset that does not permit that result. Usually, the visit is cancelled and the score returns to what it was before the turn, but house and competition rules should always be checked because details can vary.

“Going for the bull” simply means aiming at the bull or bullseye, often because it offers a possible finish or a useful scoring option. It does not automatically mean the player is attempting a special type of checkout; the intended result depends on the score left and the rules being used.

Famous combinations and match phrases

Shanghai is a combination of a single, treble and double of the same number in one visit. A common example is a 120 Shanghai on 20: single 20, treble 20 and double 20, adding up to 20 + 60 + 40. The order does not necessarily matter when people describe the combination. Some games or local formats may attach a special meaning or bonus to Shanghai, but the combination itself does not automatically carry a bonus in every ruleset.

A nine-darter is a perfect nine-dart leg in 501: the player completes the leg in the minimum number of darts under the standard format. There is more than one possible route, so the term describes the achievement rather than one fixed sequence of scores. It should also be understood in context, since starting-score and finishing rules can differ between formats.

The three-dart average is the average number of points scored per three-dart visit over a defined part of a match. It is a performance statistic, not a rule or a guaranteed score for every turn. A player can have a high average while still missing important doubles, because scoring heavily and finishing efficiently are related but separate parts of a leg.

Darts slang that can sound confusing

Madhouse is the nickname for the double-one bed. It is often associated with a difficult or frustrating finish because a player may be left needing only two points, making the narrow double one the target. The term is informal rather than an official rule name, but it is common enough to appear in commentary and conversation.

Wire can be used literally for the metal divider, or figuratively when a dart misses a target by striking its edge. A dart that is “in the wire” has not scored in the intended bed merely because it was close. Similarly, “cover” usually refers to using another target when the preferred one is obstructed, rather than naming a particular score.

Other phrases are descriptive rather than formal rules terminology. A commentator might say a player has “found the treble” after repeatedly hitting a treble bed, or has “left a finish” when the remaining score can be completed legally. These expressions are easy to understand once the basic difference between scoring, positioning and finishing is clear. For readers learning the equipment side of the game, a guide to choosing darts can provide useful context without changing the meaning of these terms.

How these terms sound in a match

A typical piece of commentary might describe a player hitting a ton, using a marker to find the treble 20, and leaving a finish. On the next visit, the player may go for the bull or attempt a planned checkout. If the final dart misses the required double, the player has not taken out the leg; if the visit goes over the remaining score, it may be a bust. A commentator discussing the wider event may also refer to the major darts tournaments where such scoring and checkout moments take place.

The key distinction is between official scoring or rules language and informal shorthand. “Double”, “treble”, “leg” and “checkout” describe standard parts of play, while “madhouse”, “ton 80” and similar phrases are familiar community language. Usage can vary slightly by region, format or darts community, but these definitions cover the terms most beginners are likely to encounter.

Once you know that a ton is 100, a ton 80 is 180, a bed is a target area, and a checkout is a legal finish, live commentary becomes much easier to follow. The remaining slang then adds colour to the game rather than getting in the way of understanding it.
