How to Bet on Darts: Match, Sets and Legs, 180s, Checkouts, Handicaps and How to Think About a Darts Bet

Updated October 2026 · By the IrishBetGuide team

Darts has exploded in popularity, with sold-out crowds at Alexandra Palace every Christmas and plenty of Irish interest, from the World Cup of Darts to Irish players on the PDC tour. It's also become a popular betting sport, because matches are quick, scoring is clear and there are loads of markets. Here's how darts betting works, from the basics to the specials, explained the way a mate would explain it at the bar.

Darts basics you need for betting

Professional darts is mostly played as "501": each player starts on 501 and races to reach exactly zero, finishing on a double (or the bullseye). Each turn is three darts. The highest score in one turn is 180 (three treble 20s).

• Leg: one game of 501.
• Set: in set-play formats, a set is usually first to three legs.
• Throw: players alternate who throws first in each leg. Throwing first is an advantage.
• Hold and break: winning a leg when you throw first is a "hold"; winning when your opponent throws first is a "break".
• Checkout: the final score to finish a leg. The highest possible checkout is 170 (treble 20, treble 20, bull).
• Nine-darter: a perfect leg of 501 in nine darts.

Leg format vs set format

Most PDC events, like the Premier League, the World Matchplay and the Grand Prix (with its double-start rule), use legs, such as "first to 11 legs". The PDC World Championship uses sets. In set format, momentum can swing in strange ways because winning a set resets the leg count. That matters for correct score and handicap markets.

The main darts markets

Match winner

Who wins the match. Most darts matches can't end in a draw, though some formats, such as certain league stages, can. Check whether a draw is possible.

Correct score

The exact final score, such as 6–4 in legs or 3–1 in sets. Higher odds, harder to land.

Handicap (legs or sets)

One player gets a head start. "Player A −2.5 legs" means Player A must win by three legs or more. Useful when there's a big favourite.

Total legs or sets

Over or under a number of legs in the match. Close matches go over; one-sided ones go under.

Total 180s

The total number of maximums in the match, or by one player. Very popular. Depends heavily on match length and players' scoring power.

Most 180s

Which player hits more 180s. Often offered with a tie option or a handicap.

Highest checkout

Which player hits the higher checkout, or whether the highest checkout goes over a number, like 100.5. A single big finish settles it, so variance is huge.

Checkout of 170, or a nine-darter in the match

Rare events with big prices. Fun, but the margins are generally large.

Leg-by-leg markets in-play

Winner of the next leg, 180 in the next leg, and so on.

Outrights

Tournament winner, top quarter winner, or special markets like "nine-darter in the tournament".

Odds and margin

As with any sport, convert odds into implied probability (1 ÷ decimal odds) and add them up. In big darts matches, the margin on match winner might be similar to football. On specials like 180s and checkouts, it's often much bigger.

These are general descriptions, not measured figures. They vary by bookmaker and match.

What actually matters in a darts bet

Averages

The "three-dart average" is the average score per three darts across a match. It's the most quoted stat in darts. Higher averages generally mean stronger scoring. But averages vary from match to match, and they don't capture finishing well.

Checkout percentage

The percentage of attempts at a double that a player converts. Great scorers who miss doubles lose legs. Checkout percentage swings a lot, especially over short matches.

Match length

Short formats, like best of 11 legs, give underdogs more chance. Longer formats tend to favour the stronger player. Early rounds of many events are short; finals are longer.

Stage vs floor events

Big "stage" events (TV, big crowds) feel different from "floor" events like Players Championships. Some players thrive on stage; others play better in quieter conditions.

Form and schedule

The PDC calendar is packed. Players can play several events in a week, and travel between Europe and the UK. Fatigue and form both matter.

Head-to-head

Some players seem to have a hold on certain opponents. Interesting, but small samples and different formats make head-to-head records less reliable than they look.

Crowd and pressure

Ally Pally crowds are loud, and some players clearly struggle with it. Others feed off it. This is hard to quantify, but worth thinking about.

Thinking about 180s properly

Total 180s markets are hugely popular. Things that push 180s up:

• Longer matches (more legs, more turns).
• Two heavy scorers who go for treble 20 a lot.
• Close matches that go the distance.
• Set formats with many legs.

Things that push 180s down:

• Short matches.
• One-sided matches that end quickly.
• Players who switch to treble 19 often or score more steadily rather than going for maximums.
• Double-start formats, such as the Grand Prix, where players must start on a double.

Because 180s depend so much on match length, your view on how close the match will be affects both your total legs bet and your 180s bet. They're linked.

A worked example (made-up numbers)

A first-to-6-legs match in a floor event. Player A, a top-16 player, faces Player B, a qualifier. Prices:

• Player A to win: 1.30
• Player B to win: 3.50
• Player B +2.5 legs: 1.85
• Total legs over 9.5: 1.90
• Total 180s over 3.5: 1.85

You know Player B has been averaging well in qualifiers, and Player A has had a poor run with his doubles. You think A probably wins, but it could be close. Options:

• Player B +2.5 legs wins if B loses 6–4 or 6–5, or wins outright.
• Over 9.5 legs wins if the match goes to 6–4 or closer.
• Over 3.5 180s depends on match length too: a 6–2 win might not produce enough.

These bets are all linked. If the match is close, you could win all three; if A thrashes B, you could lose all three. Don't think you're spreading risk if your bets all rely on the same thing.

In-play darts betting

Darts is quick, and in-play markets move after almost every visit to the board. Things to know:

• The throw matters a lot. Who's throwing first in the next leg affects the odds.
• Streams can be delayed compared with live data feeds.
• Markets are suspended during each leg's key moments.
• It's very easy to place lots of small bets that add up to a big total. Set a limit.

Common darts betting mistakes

1. Over-trusting averages. One high average doesn't make a player a lock next time.
2. Ignoring the format. A short match is far more random than a long one.
3. Backing favourites in big accumulators. Darts upsets happen every week.
4. Chasing nine-darter and 170 specials. Fun, but the margins are high.
5. Doubling down on linked bets. Over legs, over 180s and the underdog on the handicap are often all the same bet in disguise.
6. Betting on everything at the Worlds. The PDC World Championship runs for weeks around Christmas. That's a lot of temptation.

Where Cloudbet fits in

Cloudbet lists darts markets on major events, typically including match winner, handicaps, totals and some specials, with decimal odds. It's licensed in Curaçao and not licensed by the GRAI, so there's no Irish complaints route and Irish safer-gambling rules don't apply. For those protections, use a bookmaker on the GRAI register. We never explain how to get around blocks or restrictions.

The darts calendar and the big events

Dates and formats change, so check the PDC's official calendar. The WDF also runs events, including its own world championship, with different formats and players.

The Irish angle

Ireland competes at the World Cup of Darts as a nation, and Northern Irish players compete for Northern Ireland. Players from both the Republic and Northern Ireland, such as William O'Connor, Keane Barry, Daryl Gurney and Brendon Dolan, have been regulars on the PDC circuit over the years. It's natural to want to back the home players, and there's nothing wrong with a small bet for the craic, but betting with your heart isn't a strategy. Prices on popular players can be shorter than their chances justify when lots of fans back them.

Understanding the throw: holds and breaks

Because the player throwing first in a leg has a real advantage, darts matches are often analysed like tennis: who holds throw and who breaks. In a first-to-6 legs match, if both players hold throw every time, the score goes 5–5 and then the player throwing in the deciding leg has the edge. A single break can decide the match. This is why:

• Who throws first in the match matters in short formats.
• Correct score markets often cluster around close scores between evenly matched players.
• In-play prices swing dramatically after a break of throw.

Common checkouts

You don't need to know checkouts to bet, but it helps you follow matches and highest-checkout markets:

Scores of 169, 168, 166, 165, 163, 162 and 159 can't be checked out with three darts. Players can take routes in different orders, and many have personal preferences.

Double-start events

The World Grand Prix requires players to start each leg on a double, as well as finish on one. That makes legs longer and more random, reduces 180s in the early stages of legs, and can produce surprise results. Markets adjust, but if you're betting on totals or 180s, remember the format.

Women's darts and other tours

Women's darts has grown significantly, with players like Beau Greaves and Fallon Sherrock attracting big audiences. The PDC Women's Series and WDF events offer more betting markets than they once did, but data and pricing are thinner. Youth and development tours exist too, though markets on them are limited. As always, smaller markets mean bigger margins and less information.

Integrity in darts

Darts is regulated for integrity by the Darts Regulation Authority (DRA), which oversees anti-corruption rules and investigates suspicious betting. Players are not allowed to bet on matches in events they're involved in. As a punter, be wary of strange price moves in small floor events, and never act on anyone claiming to know a result in advance.

A simple darts betting routine

1. Check the format: legs or sets, length, any double-start rule.
2. Check who throws first, if known.
3. Look at recent averages and checkout percentages, over several matches, not just one.
4. Consider stage vs floor, and how each player has handled big crowds.
5. Think about the schedule and travel.
6. Form your own view of the likely score.
7. Pick the market that matches that view, keeping in mind which bets are linked.
8. Stake small, and record the bet.

Staking and records

Because darts is fast and fixtures are frequent, it's worth being disciplined. Use a fixed stake, such as 1–2% of a monthly budget, per bet. Keep a log of every bet with the event, format, market, odds, stake and result. After a few months, look at your results by market type: many people find that specials like 180s and checkouts cost them more than they expected.

Darts betting glossary

• Ton: a score of 100 or more in a visit.
• Ton-plus checkout: a checkout of 100 or more.
• Bed and breakfast: a score of 26 (a 20, 5 and 1), the classic bad visit.
• Madhouse: needing double 1 (2 points) to finish. Notoriously awkward.
• Shanghai: hitting a single, double and treble of the same number in one visit.
• Whitewash: winning a match without dropping a leg or set.
• Break of throw: winning a leg your opponent started.

Set play explained, with an example

At the PDC World Championship, matches are played in sets, and each set is usually first to three legs. Early-round matches might be first to three sets; the final is much longer. Set play makes some things odd:

• A player can win more legs overall but lose the match. For example, winning sets 3–0 and 3–0 then losing three sets 2–3 gives a 2–3 set defeat with 12 legs to 9 in your favour.
• Leg handicap and total legs markets behave differently from set markets.
• Momentum within a set can matter, because the leg count resets at the start of each one.

If you're betting on set handicaps, remember that a 3–2 set win can come with almost any leg count.

How averages relate to winning chances

A rough rule many fans use is that the player with the higher average tends to win more often, and the bigger the gap, the more likely the stronger player wins. But a few points of average difference over a short match doesn't guarantee much, because:

• Averages include all visits, including scores after a leg is already won or lost.
• Doubles decide legs, and checkout percentage can swing hugely in one match.
• One player throwing first in more legs can make their stats look better.

Use averages over a reasonable number of recent matches, and look at checkout percentage alongside them, rather than relying on a single headline number.

Outright betting: a few pointers

• Check the draw. A favourable quarter can matter a lot in events where the format gets longer in later rounds.
• Consider each-way if it's available, but read the place terms carefully.
• Think about format. Long formats favour the top players; short formats spread the chances.
• Remember that money is tied up, sometimes for weeks over Christmas at the Worlds.
• Don't stack too many outright bets in the same event; most of them will lose.

Specials: fun, but price them honestly

Bookmakers love darts specials: a nine-darter in the tournament, a 170 checkout in a match, a player to hit more than a certain number of 180s across an event. These can be a laugh with a small stake. But ask yourself whether you have any real reason to think the price is wrong, or whether it's just a lottery ticket. Most of the time, it's the latter, and the bookmaker's margin on these markets is usually high.

Watching darts in Ireland, and pub betting nights

Darts nights in the local are part of the fun, and the big PDC events are usually on TV or streaming services. If you're betting with friends, a few simple rules keep it friendly: agree a small kitty in advance, keep side bets modest, and don't let anyone chase losses on the next match. If you're watching a big Ally Pally session late at night, it's easy for stakes to drift upwards as the evening goes on. Decide your total for the night before the first match, and stop when it's gone.

Is darts more predictable than other sports?

Sometimes it feels that way, because top players often win. But darts has plenty of randomness, especially in short formats where a couple of missed doubles can decide a match. Bookmakers know the top players' strengths as well as you do, and their prices already reflect them. Darts isn't a shortcut to profit; it's a sport where small edges, if they exist at all, are hard to find and easy to lose to the margin.

Bet builders in darts

Some bookmakers let you combine darts markets into a single "bet builder", such as Player A to win, over 9.5 legs and over 4.5 180s. Because these outcomes are linked, bookmakers price them with correlation in mind and usually add an extra margin. They can produce attractive-looking odds, but they rarely offer better value than individual bets. If you use them, keep stakes small and treat them as entertainment rather than a smarter way to bet.

And if you're just getting into darts, there's a lot to be said for watching a full tournament without betting at all. You'll learn the players, the formats and the rhythm of the game, and you'll be far better placed to judge prices later.

Responsible gambling

Darts runs most nights of the week in season, and the Worlds run straight through Christmas. Decide on a budget and stick to it, and don't let a few drinks at a darts night decide your stakes. If gambling is affecting your life, call the Problem Gambling Helpline, free and open 24/7, on 1800 936 725 (Northern Ireland: 08000 886 725). See our responsible gambling page for more.

In short

Darts betting is about more than who wins: legs, sets, 180s and checkouts all have markets. Understand the format, the throw, averages and checkout percentages, and remember that many markets are linked to how long a match lasts. Short formats are random, specials carry big margins, and in-play moves fast. Bet small, and enjoy the arrows.
