Darts terms from A to Z

Leg, set, average, checkout, bogey, double out, MPR: the key darts terms explained briefly and clearly.

Darts has its own language. Here you'll find every term used in the app and in this help. In the articles they are underlined: tap one to see the explanation right away.

Throw
Who throws first in a leg. The throw alternates from leg to leg so that nobody has a lasting advantage.
Visit
The three darts you throw one after another before it's the next player's turn. Also called a "round" or "turn".
Set up
Reducing a score so that a comfortable double is left. With 59 left, for example, a 19 sets up double 20.
Bull-off
Everyone throws one dart at the bull. Whoever lands closest to the centre starts the game or wins a tie.
Average (3-dart average)
The average points you score per visit of three darts. Casual players are often between 30 and 50, pros above 90.
Best of
At most the stated number of legs is played. In "best of 5", whoever has 3 legs first wins.
Big Fish
The highest possible finish: 170 with treble 20, treble 20 and bullseye.
Bogey number
A score below 170 that can't be finished in one visit with double out: 169, 168, 166, 165, 163, 162 and 159.
Bot
A computer opponent. It aims at a segment and scatters like a person, at a fixed skill level.
Bull
The green ring around the centre of the board. It's worth 25 points and is also called "single bull".
Bullseye
The red dot in the centre of the board. It's worth 50 points and counts as a double, so it can finish a leg with double out.
Checkout
Finishing a leg: bringing the score to exactly 0, with double out with a double as the last dart. Also called a "finish".
Checkout rate
How many of your darts at a double to win a leg hit. 3 hits from 12 attempts are 25 %.
Cricket
A game in which you hit the numbers 15 to 20 and the bull three times each to "close" them while collecting points.
Double
The narrow outer ring of the board. A hit counts twice: double 20 (D20 for short) is worth 40 points.
Double in
A rule where your points only count once you've hit a double. Until then your starting score stays put.
Double out
The usual rule: the last dart of a leg must be a double or the bullseye. A score of 1 left can then no longer be played.
First 9
Your average over the first three visits (nine darts) of a leg. It shows how well you score before it comes to checking out.
First to
Whoever wins the stated number of legs or sets first wins the match. "First to 2 legs" means two won legs are enough.
Favourite double
The double you like most or hit most reliably. The checkout help can base its routes on it.
Leg
A single game from your starting score down to 0. Several legs make a set or a match.
Marks
Hits in Cricket: a single is one mark, a double two, a treble three. Three marks close a number.
Master out
The last dart of a leg must be a double, a treble or the bullseye.
Miss
A dart without points: off the board, outside the double ring or bounced out. In the app you tap "Miss" for it.
MPR
"Marks per round": how many marks you hit per visit on average in Cricket. From about 2 you're playing solidly.
Nine-darter
A 501 leg with only nine darts, the perfect leg. Even pros rarely manage it.
Oche
The throwing line you stand behind when throwing. In steel-tip darts it's 2.37 m from the board.
Remaining
The points you still need in an X01 leg to reach 0. It's shown large on your player card.
Segment
One of the 20 cake-slice-shaped areas of the board. Each has a number from 1 to 20 and a single, double and treble area.
Set
A group of legs. Whoever wins enough legs wins the set; whoever wins enough sets wins the match.
Shanghai
Single, double and treble of the same number in one visit. In the party game of the same name, it wins you the game instantly.
Single
The large areas of a segment. A hit scores the plain number: single 20 is worth 20 points.
Single out
Any dart may finish the leg if it brings the score to exactly 0. Good for beginners.
Steel-tip darts
Darts with a metal point thrown at a sisal board. The app scores steel-tip darts; for soft-tip, Cricket has a variant without the bull.
Ton
A visit of 100 points or more. The maximum is 180 points with three treble 20s.
Triple
The narrow inner ring of the board. A hit counts three times: treble 20 (T20 for short) is worth 60 points.
Bust
You've scored more points than you needed, or left a score of 1 with double out. The whole visit then doesn't count.
Handicap
Different starting scores or rules for players of different strength, so everyone has a fair chance.
White Horse
In Cricket, three trebles on three different, still open numbers in one visit.
X01
The umbrella name for 301, 501 and similar games: everyone starts with the same score and counts down to exactly 0.
