- 128 players
- First championship
- 1994, Purfleet
Seven wins. That is the whole distance between the first dart thrown at Alexandra Palace in north London in the middle of December and the Sid Waddell Trophy in the first days of January. The PDC World Championship is a straight knockout with no groups, no second chances and no seeding byes since the field grew to 128 players for the 2026 event. Lose once and the fortnight is over.
What sets it apart from almost everything else the Professional Darts Corporation runs is the scoring. Matches are played in sets, and each set is the best of five legs of 501, so three legs win a set. The matches lengthen as the rounds go by: the best of five sets in the first two rounds, the best of seven in the third and fourth, nine in the quarter-finals, eleven in the semi-finals and the best of thirteen in the final. A deciding set that reaches two legs all must be won by two clear legs, with a sudden-death leg at five-all.
The PDC World Championship format at a glance
One table carries most of it. The figures below are the format the PDC used at the 2026 championship, the first with 128 players, and which it kept for the event that follows.
| Round | Players left | Match length | Sets needed to win |
|---|---|---|---|
| First round | 128 | Best of 5 sets | 3 |
| Second round | 64 | Best of 5 sets | 3 |
| Third round | 32 | Best of 7 sets | 4 |
| Fourth round | 16 | Best of 7 sets | 4 |
| Quarter-finals | 8 | Best of 9 sets | 5 |
| Semi-finals | 4 | Best of 11 sets | 6 |
| Final | 2 | Best of 13 sets | 7 |
Every leg inside those sets is ordinary 501: straight in, double out, the same game played on every stage of the tour and set out in our guide to the rules of a leg of 501. Nothing about the leg changes at the worlds. What changes is the container the legs are poured into.
- 128Players in the draw
- 7Rounds to win the title
- 3Legs needed to win a set
- 7Sets needed to win the final
The format as played from the 2026 championship onwards. A set is the best of five legs; the final is the best of thirteen sets.
A champion therefore wins 3, 3, 4, 4, 5, 6 and 7 sets across the tournament, which is 32 sets and at least 96 legs without losing a match. Nobody in the field has an easier arithmetic than that. From the 2019 championship to the 2025 one the 32 seeds skipped a round and needed six wins; the expansion took that privilege away and gave every player the same ladder.
What "best of" hides
A best-of-thirteen final does not mean thirteen sets get played. The 2026 final finished 7-1, eight sets in all. The 2007 final, the last at the Circus Tavern, went to the thirteenth set and then to a sudden-death leg. Same format, a match roughly twice as long. Schedules at the worlds are built around that uncertainty, which is why the late rounds are given so few matches per session.
Round by round: how many sets, how long, and who it favours
A first-round match can be finished in nine legs. Three sets, each won 3-0, and the loser has not taken a leg in the biggest tournament of the year. A whitewash that complete is rare. The format allows it all the same, and the schedule has to allow for it too.
The other extreme is worth working out, because it explains the scheduling. A best-of-five-set match that goes the distance, with every set reaching a fifth leg and the decider running through the full tie-break, lasts 31 legs: four sets of five and a last set of eleven. The chart shows the same sum for each stage.
Time follows from legs. At this standard a leg takes a couple of minutes of throwing, and the gaps between sets and the scheduled breaks add to that, so a one-sided early match is done in well under half an hour and a tight one takes the better part of an hour. A semi-final that goes deep can pass two hours. The PDC does not publish target durations, and the figures here are a guide to the shape rather than a promise.
Why length suits the better player
The claim that long matches favour the stronger player is made every year from the quarter-finals onward, and it is sound, though the reason is duller than the commentary makes it. A leg of darts between two professionals is close to a coin weighted slightly one way. Over nine legs the lighter side of the coin comes up often enough to matter. Over fifty it mostly does not.
Sets add a second layer. To beat a better player over nine sets, the underdog has to win five separate small contests, and each one resets to nil-nil. A hot ten minutes wins a set. It does not win a quarter-final. That is why the surprises at Alexandra Palace cluster in the first two rounds, where three sets are enough, and why the names in the last four tend to be ones the Order of Merit would have predicted.
There is a cost. The early rounds are the ones in which a seed can go out to a player nobody in the hall had seen before, and the expansion to 128 added a whole round of exactly those matches. Whether that is a flaw depends on what a world championship is for. As a way of finding the best player it is noisy at the start. As an event, the noise is half the point.
Why the worlds counts sets when the rest of the PDC calendar counts legs
Look down the list of PDC tournaments and nearly all of them are leg play: first to six on the floor, first to ten or eleven in the early rounds of the majors, longer at the end. The World Matchplay is the purest example, with matches that must be won by two clear legs and no sets at all, as our page on the World Matchplay at the Winter Gardens explains. Set play survives at the top level in only a handful of events. The worlds is the one that matters most.
Part of the reason is inheritance. The championship the PDC's founders walked away from in 1993 was a set-play event, and they kept the scoring their audience already understood when they staged their own. The story of that walk-out is told in our account of the split between the PDC and the BDO. But inheritance alone would not have kept sets alive for three decades. They do something legs do not.
Winning more legs and losing the match
In leg play the scoreboard cannot lie: whoever wins more legs wins. In set play it can. Take a best-of-five-set match in which one player wins two sets 3-0 and loses the other three 3-2. He has won twelve legs to his opponent's nine. He has also lost the match by three sets to two.
That is not a quirk at the edges. It is the mechanism. Sets value the legs at the end of each set far more than the legs at the start, because the fifth leg of a set at two-all is worth the entire set and the first leg is worth a third of one. A player who is brilliant early in sets and tightens at the finish will lose to one who does the opposite. Leg play averages those moments out. Set play isolates them.
Momentum and the reset
Sets also change how a deficit feels. A player 5-1 down in a first-to-ten leg match has to win nine of the next thirteen legs. A player two sets down in a best-of-five starts the third set at nil-nil in legs, and a single break of throw brings him back into the match. The scoreboard keeps offering a fresh start, which is why comebacks from two or three sets behind are a regular feature of the tournament and almost unknown at the same margin in legs.
It cuts the other way too. A set lost 3-0 costs exactly what a set lost 3-2 costs. Experienced players use that. If a set has gone, they will sometimes throw it away on their own terms, slow down, try a different line on the treble, and come out for the next one with the throw. Fuller detail on the two scoring systems sits in our guide to legs and sets across the different formats.
The throw in set play and what a break of throw is worth
Before a match starts both players throw one dart at the bull, and the nearer one throws first in the opening leg. The procedure for the bull itself, including what happens when both darts land in the same segment, belongs to the Darts Regulation Authority rule book and is covered in our page on who throws first and how the bull-up works. At the worlds it matters more than anywhere, for a reason that only shows itself late in a match.
The throw alternates in two ways at once. Within a set it alternates leg by leg, so the player who starts the set throws first in legs one, three and five. Between sets it alternates too: whoever threw first in the opening set throws second in the next, first again in the third, and so on down the match.
| Set | Throws first in leg one | Has the throw in a fifth leg |
|---|---|---|
| First | Winner of the bull | Winner of the bull |
| Second | Loser of the bull | Loser of the bull |
| Third | Winner of the bull | Winner of the bull |
| Fourth | Loser of the bull | Loser of the bull |
| Any deciding set | Winner of the bull | Winner of the bull |
The last row is the one to notice. Every match at the championship is the best of an odd number of sets, so a deciding set is always an odd-numbered set, and odd-numbered sets always start with the player who won the bull. One dart thrown at the bull before the first leg decides who has the advantage in a decider that may be two hours away.
Holding and breaking
Throwing first is an advantage because the player on throw gets to the double first if both score the same. To "hold" is to win a leg in which you threw first. To "break" is to win one in which you did not. In a set where every leg is held, the player who began it wins 3-2, having thrown first in three of the five legs.
So the player starting a set needs no breaks. The player starting it second needs one, and winning a set that way is what the commentators mean by winning it "against the darts". Across a match the burden evens out, since each player starts alternate sets. But the unit is small. One break is enough to win a set, and one break straight back restores the balance. In a long leg-play match a break is a small dent. In a set it is close to the whole thing.
This is also why the set score alone tells a viewer less than it seems to. Two sets all in a best-of-five could mean four holds of serve, in tennis terms, with the bull winner about to start the decider. Or it could mean four sets won against the darts and nothing predictable about the fifth.
The World Championship tie-break rule: two clear legs, then sudden death
On the first day of 2007, at the Circus Tavern in Purfleet, Raymond van Barneveld and Phil Taylor reached six sets all in the final, then two legs all in the thirteenth set, then five legs all. The title was settled by one leg. Van Barneveld won it, and the PDC has rarely had a better advertisement for a rule.
The rule is this. In the deciding set of a match, and only in the deciding set, reaching two legs each does not produce an ordinary fifth leg. Play continues until one player leads by two clear legs. If neither has managed that by five legs each, a single sudden-death leg is played and its winner takes the set and the match. The longest deciding set the format allows therefore finishes six legs to five.
- Sets levelThe match reaches the last possible set, for instance two sets all in a best-of-five or six all in the final.
- Normal play to two-allThe set starts as any other. If a player wins it 3-0 or 3-1, the match ends there and no tie-break arises.
- Two clear legsFrom two legs each, the set continues until one player is two legs ahead, so 4-2, 5-3 or 6-4 all win it.
- Five legs eachIf the players are still level after ten legs, the two-clear requirement is dropped.
- Sudden deathOne further leg is played. Whoever wins it wins the set, the match and the place in the next round.
The sequence in the PDC's World Championship format. It applies only to the final possible set of a match, never to earlier sets.
Earlier sets are untouched. A second set at two legs all goes to a fifth leg and stops, whatever the stage of the tournament. The tie-break is a device for ending matches, not sets.
The rounds it has and has not covered
The coverage has changed more than once. In the first years at Alexandra Palace the rule applied to every match that reached a final set: the format for the 2009 championship says so in terms. Later, in the 96-player era, the first round was left out. The formats for the 2020, 2023 and 2025 championships all exclude it, so a first-round decider that reached two legs all was settled by a plain fifth leg, and the two-clear rule began in the second round. Sessions with four matches in them are hard to schedule around open-ended finishes, which is the usual explanation. That was the position at the 2025 championship.
At the 2026 event the exemption went, and the tie-break applied in every round from the first match of the first session. Anyone reading an older account of the format, or remembering a first-round match that ended 3-2 in a fifth set without extra legs, is remembering correctly. The rule changed.
Who throws in the sudden-death leg
In the 2007 final the players threw at the bull again to decide who would throw first in the last leg, which produced its own piece of theatre. Taylor went first and hit the outer bull, van Barneveld asked for that dart to be left in the board, and his own went into the bull beside it. The idea was that a leg carrying a world title should not be handed to whichever player the alternation happened to favour, and the bull-off was still in the format for the 2020 championship.
It has since gone. The formats for the 2023 and 2025 championships state that the sudden-death leg is played with no throw for the bull, so the throw simply continues to alternate. The eleventh leg of a set is an odd-numbered leg, which means it falls to the player who threw first in that set: in a decider, the winner of the bull before the match. A reader who remembers the 2007 final should treat it as history and not as the present rule.
How many players are in the PDC World Championship and where they come from
From the 2026 championship the answer is 128, up from the 96 who had played each year since the 2019 event. The places are divided between two ranking lists and a set of qualifiers.
- Main Order of Merit31.3%
- ProTour Order of Merit31.3%
- International and other qualifiers37.5%
The qualification split the PDC used for the 2026 championship and retained for the following event. The international group covers regional tours, secondary tours and qualifying tournaments.
Show the numbers
| Item | Value |
|---|---|
| Main Order of Merit | 40players |
| ProTour Order of Merit | 40players |
| International and other qualifiers | 48players |
The first forty come from the main Order of Merit, the two-year list of prize money won in ranking events that functions as the world rankings. How that list is built, and why it rewards consistency over two seasons, is the subject of our guide to how the PDC Order of Merit works. The top 32 of those forty are the seeds.
The next forty are the highest players on the ProTour Order of Merit who have not already qualified. That list counts one year of money from the Players Championship floor events and the European Tour, so it rewards a good current season and catches players the two-year list has not caught up with: newer tour card holders, or established names whose big cheques have dropped off.
The remaining 48 are the hardest to summarise, because the PDC adjusts the list from year to year. In broad terms they are the winners and leading players from the affiliated regional tours in Asia, North America, Australia, New Zealand, the Nordic and Baltic countries and elsewhere; the leading players from the Development Tour, the Challenge Tour and the Women's Series; the World Youth champion; and the winners of qualifying tournaments, including one for tour card holders who have missed out through the rankings. The exact allocation for any one year is published by the PDC and should be checked there.
What the growth to 128 did to the seeds
Under the 96-player format the 32 seeds were excused the first round. Sixty-four players contested it, the 32 winners advanced, and the seeds entered at the second round against opponents who already had a win on the stage behind them.
At 128 that no longer works, and nobody is excused anything. Every seed plays in the first round. The number of matches rose from 95 to 127, the first round became a block of 64 matches, and a seed's path to the title grew from six wins to seven. The trade is straightforward: seeds lost a free pass, and gained a first opponent who has not yet thrown a competitive dart in the hall.
Seeding and the draw: reading a route off the bracket
The draw is made once, a few weeks before the event, and then it is a fixed bracket. Nothing is redrawn between rounds. That is the main difference from the UK Open, whose open draw after every round is the whole point of the tournament.
The 32 seeds are placed in the bracket by ranking, on the conventional pattern: the first and second seeds in opposite halves, the top four in separate quarters, the top eight in separate eighths. The unseeded players are then drawn into the gaps. The PDC has varied the way those unseeded names are grouped for the draw, so the detail of who can be drawn against whom in round one is something to take from the year's own announcement.
Because the bracket is fixed, a seed's possible route can be read straight off the sheet. Following the standard pattern for the top seed:
| Round | Top seed's scheduled opponent |
|---|---|
| First round | An unseeded player |
| Second round | The winner of a match between two unseeded players |
| Third round | The 32nd seed's section |
| Fourth round | The 16th or 17th seed's section |
| Quarter-final | The 8th or 9th seed's section |
| Semi-final | The 4th or 5th seed's section |
| Final | The other half of the draw |
"Section" is doing honest work in that table. A seed is only a seed until he loses, and when the 32nd seed goes out in round one the player who beat him inherits the slot. A draw sheet tells a player whom he might meet, never whom he will.
The seeding list is fixed from the Order of Merit as it stands after the last ranking event before the championship, which gives the final weeks of the autumn an edge that has little to do with the tournaments being played. A player on the boundary of the top 32, or the top sixteen, is playing for his position in the bracket as much as for the title in front of him.
The shape of the event: December start, Christmas break, January final
No other major in British sport sits where this one does. The championship opens in the middle of December, plays through the week before Christmas, stops, and resumes for the run to a final in the first days of January. The 2026 championship ran from 11 December to 3 January, and the first round alone took until 19 December.
The pause is short and fixed by the calendar. There is no darts on Christmas Eve, Christmas Day or Boxing Day. Play has resumed on 27 December in recent years, with the players who are still in having had three days at home and a practice board for company. Some say it breaks their rhythm. The schedule does not ask them.
Most days are split into an afternoon session and an evening session, each sold as a separate ticket. In the early rounds a session carries several matches of the shortest length. As the matches lengthen, the number per session falls, until the quarter-finals are divided across two sessions on New Year's Day and the semi-finals share one evening. The final has a night to itself.
For a British audience the placement is the making of the tournament. It fills the days between Christmas and New Year, when little other live sport is played in the evening, and it has become a fixture of that week in the way the Boxing Day racing or the New Year's Day football programme are. The venue has its own page here, on what to expect at Alexandra Palace, including the move from the West Hall to the Great Hall.
The length of the event follows from the size of the field. A 96-player championship needed 95 matches; a 128-player one needs 127. The extra round was absorbed by starting earlier in December, four days earlier at the 2026 event than the year before, and the Christmas break and the date of the final were left where they were.
One consequence for the players is easy to miss. A seed who plays his first-round match in the opening days may wait a week or more for his second, and a player drawn late in the first round may play twice in three days either side of Christmas. The bracket is fair. The diary is not quite.
The Sid Waddell Trophy, the winner's cheque and the ranking
The champion is handed the Sid Waddell Trophy, renamed for the 2013 championship after the commentator's death in August 2012. Waddell's voice had described the sport on British television for more than thirty years, and the PDC's decision to put his name on its most important prize was one of the less arguable ones it has made.
The money is the other prize, and at the 2026 championship it changed scale. The total fund was £5 million and the winner received £1 million, double the £500,000 paid the year before.
| Stage reached at the 2026 championship | Prize |
|---|---|
| Winner | £1,000,000 |
| Runner-up | £400,000 |
| Losing semi-finalists | £200,000 |
| Losing quarter-finalists | £100,000 |
| Fourth-round losers | £60,000 |
| Third-round losers | £35,000 |
| Second-round losers | £25,000 |
| First-round losers | £15,000 |
Those figures are dated to that event and will move. What does not move is the mechanism. The Order of Merit is a rolling total of ranking prize money over two years, and the world championship pays far more than any other ranking event, so the winner's cheque is the largest single entry any player can have on the list. A champion typically goes to the top of the rankings, or close to it, on that one result.
Money that falls off
Two years later it leaves. When the championship comes round again, the prize money a player won at the edition two years earlier is removed from his total and replaced by whatever he wins this time. Players and commentators call this "defending" money, which is an odd word for it, since nothing is defended; the old sum is simply deleted on schedule.
The effect is severe at the top. A former champion who loses early two years after his title can drop several places in a week without having played badly anywhere else. A first-round loser, by contrast, has only the smallest prize to replace. The championship therefore sets the next season's seedings twice over: by what is won at it, and by what expires because of it.
How the format compares with the PDC's other set-play majors
Set play is not unique to the worlds, and the comparison shows what the championship's version is tuned to do.
The World Grand Prix uses sets of the same length, the best of five legs, but every leg must be started on a double as well as finished on one. Its matches are much shorter in the early rounds, and the combination of short sets and a double start makes it the most volatile major on the calendar. Our guide to the double-start format of the World Grand Prix goes through it. The World Masters, in its PDC form, shortened the sets themselves, so that a set can be won with two legs.
Outside the PDC the tradition is kept by the World Darts Federation's own championship at Lakeside, the descendant of the event the PDC's founders left, which is likewise scored in sets of five legs. Two world championships, run by rival bodies for most of three decades, never disagreed about that.
Against those, the world championship is the long form. Its sets are the standard length, its early matches are short enough to produce upsets, and its late matches are long enough that a player cannot win one on a single good spell. Thirteen sets is a great deal of darts. It is also the only match of the year in which stamina, in the plain sense of throwing well for two hours with the lights on and a title at stake, is tested at all.
A fair criticism is that the first two rounds are too short for the prize money now attached to them. A best-of-five-set match can turn on a single fifth leg, and with the smallest cheque at the 2026 event standing at £15,000 and the next at £25,000, a great deal rides on a few darts at a double. The PDC's answer, in effect, was to extend the tie-break to the first round. That lengthens the closest matches. It does nothing for a player who loses three sets 3-2 and goes home having won six legs to his opponent's nine.
From 24 players in groups at Purfleet to 128 at Alexandra Palace
The first championship did not look like this one. It was played from 28 December 1993 to 2 January 1994 at the Circus Tavern, a cabaret venue beside the A13 in Purfleet, Essex, under the name of the World Darts Council. There were 24 players, and they did not start in a knockout.
They were drawn into eight groups of three. Each group played three matches in a set order: two players met, the loser of that match played the third player, and then the winner of the first match played the third player. The group winners went into quarter-finals over the best of seven sets, semi-finals over nine and a final over eleven. Dennis Priestley beat Phil Taylor 6-1 to become the first champion.
The groups lasted until the 1999 championship, when the field grew to 32 and the organisers made the event a straight knockout for the first time. It has been one ever since. From there the growth came in steps.
| Championship | Field | What changed |
|---|---|---|
| 1994 | 24 | Eight groups of three, then a knockout from the quarter-finals |
| 1999 | 32 | Groups dropped; straight knockout throughout |
| 2003 | 40 | Extra early round for the lower-ranked entrants |
| 2004 | 48 | Field widened again, seeds entering later |
| 2006 | 64 | A full six-round bracket with every player starting together |
| 2008 | 68 | Preliminary round for international qualifiers, on the move to Alexandra Palace |
| 2019 | 96 | Seeds given a bye to the second round |
| 2026 | 128 | Seven rounds, with all 32 seeds in the first |
The preliminary round that arrived with the 2008 event was played in legs, not sets. The field rose to 70 at the 2009 championship and settled at 72 from 2010 until the jump to 96. The final, eleven sets long in the 1990s, was lengthened to the best of thirteen around the turn of the century and has stayed there.
Two changes of place matter as much as the changes of size. The championship left Purfleet after the 2007 final and opened at Alexandra Palace in December of that year for the 2008 event. And after nineteen championships in the West Hall, the PDC announced a move within the building to the larger Great Hall for the event that follows the 2026 championship. The roll of winners across all of it, with the BDO's separate championship alongside, is in our list of every darts world champion.
Reading a World Championship scoreline correctly
Because sets hide legs, the headline score of a match at the worlds is a blunt instrument. A few habits make it sharper.
Look at the legs inside the sets, which the PDC's results always give. A 4-1 win made of sets won 3-2, 3-2, 3-2 and 3-2 was a close match that one player kept winning at the last. A 4-3 win in which the loser's three sets were all 3-0 was a match the loser dominated in patches and lost when it mattered.
Check who had the throw in the deciding set. If the bull winner took the decider with three holds, he has done nothing more than was expected of him. If the other player took it, he broke throw in the highest-pressure set of the match.
Count the breaks of throw across the whole match where the statistics give them. A match with almost none was decided by the bull and by one or two legs; the players were holding throw and waiting. A match full of breaks was scrappier and more open than the set score suggests, and usually better to watch.
Treat averages with care. A three-dart average is calculated across every dart thrown in the match, so it weights the legs equally, and set play does not. A player can post the higher average and lose 3-0 in sets if his good legs came in bunches and his opponent's came at two legs all. Our guide to how a three-dart average is worked out explains what the number can and cannot tell a reader.
And remember what a nine-darter is worth. A perfect leg is one leg, a third of a set. Michael Smith threw one in the 2023 final and it is rightly remembered, but it moved the scoreboard by exactly as much as a leg won in twenty-four darts. The format pays for legs at the right moments. It has no way of paying extra for beauty, apart from the separate bonus the PDC puts up for it.
