EuroLeague format explained: 20 clubs, play-in, Final Four
How the EuroLeague format works: twenty licensed clubs, a 38-game double round robin, the Play-In Showdown, best-of-five playoffs and a Final Four.
By CricketTaken EditorialPublished Guide19 min read
A club can finish twentieth in the EuroLeague and be back in it the following September. A club can win its national championship four years running and never get in at all. Neither of those is a flaw in the competition, and both follow from the same design decision, which is where any honest account of the EuroLeague format has to start: the entry ticket is a licence, not a league position.
That one fact does more work than anything else in explaining why the competition looks the way it does. It is why there are exactly twenty clubs. It is why the regular season is thirty-eight games long when no domestic league in Europe asks that of the same players. It is why the season ends with a weekend rather than a series. And it is why the argument about the EuroLeague is never really about the bracket, it is about who is allowed to be in the room.
What follows is the whole structure, phase by phase, from the licence to the trophy, with the parts that are usually left out.
The EuroLeague format begins with a licence, not a league table
The competition is run by Euroleague Basketball, whose commercial arm, Euroleague Commercial Assets, is owned by the clubs themselves and a number of domestic leagues. The bylaws set the size of the competition in a single line: ECA will grant twenty licences to operate teams in the EuroLeague.
Those twenty licences come in two types, and the distinction between them is the whole political story of European basketball.
Licensed Clubs hold a long-term licence. The bylaws define them as clubs that participate in the EuroLeague on a long-term basis, and they are the shareholders in ECA. They are not playing for their place each spring. They own part of the competition.
Associated Clubs participate on a one-season basis, either with an annual licence or through a wild card. They sit in the General Assembly, the body that governs the competition, but the bylaws are explicit that they do so with no voting rights.
The criteria for a long-term licence are set out in the licensing rules and they are not sporting criteria at all. A club needs a defined territorial area, described as a population of 200,000 inhabitants within a defined geographical zone, and an additional licence is only granted in the same area if the population exceeds that. It needs an arena with a minimum capacity for 10,000 seated spectators, within a four-hour commercial flight of Frankfurt am Main, which the rules nominate as the notional centre of the European Union for this purpose. It needs at least two four-star hotels within 25 km of the arena by road, and an international airport within 100 km with enough daily flights that visiting teams are not wrecked getting there. It has to satisfy the EuroLeague Financial Stability and Fair Play Regulations, and it has to be clean legally, with no conflict of interest with another participating club and no involvement in agencies representing players or coaches.
Read that list again and notice what is missing. There is nothing in it about winning.
One clause deserves more attention than it usually gets. Where two or more Licensed Clubs already come from the same domestic league, the bylaws state that no additional Licensed Club licences will be granted to clubs from that league. It is a cap on national concentration, written into the licensing rules rather than left to negotiation, and it is the reason a strong third club in a strong basketball country can find the long-term door closed regardless of how it plays.
The split between long-term and one-season licences is not fixed in the bylaws, and anyone who tells you it is has not read them. The additional provision at the end of the licensing rules puts it plainly: the General Assembly is responsible for establishing, before the end of each season, the competition system and the allocation of EuroLeague licences for the following season. Twenty is the constant. Which twenty, and on what terms, is decided annually by the clubs who are already in.
- 20Licences granted to operate teams
- 38Regular-season games per club
- 3Games needed to win a playoff series
- 4Clubs at the Final Four
All four are fixed by the EuroLeague bylaws rather than set each season. The regular-season figure is the double round robin among twenty clubs.
Twenty clubs, thirty-eight games, one table
The regular season is a straight double round robin. Each of the twenty clubs plays all nineteen others home and away, which is thirty-eight games, and there are thirty-eight rounds. Across the competition that is 380 games before a single knockout tie is played.
There are no conferences, no divisions and no seeding groups. One table, twenty clubs, ranked by games won.
For the 2026-27 season the competition's own format page puts the regular season between Thursday 24 September 2026 and Friday 16 April 2027. Just under seven months, thirty-eight games, played midweek, while every club in it is also playing a full domestic league season and, in most cases, a domestic cup. That is the quiet cost of the closed structure. A Spanish or Turkish or Greek club in the EuroLeague plays a two-competition season with one squad, and the bylaws let it register a maximum of sixteen players at any one time, with no more than twenty used across the whole season.
The thirty-eight-game shape matters for a reason that is easy to miss. In a double round robin every club plays an identical schedule, so the table is not distorted by an easier or harder draw the way a group-based competition is. There is no equivalent of the argument that dominates the Champions League every autumn about who got the kind fixture list, because in the EuroLeague there is no fixture list to get. Everybody plays everybody, twice. If you want to compare the two approaches to filling a European calendar, the contrast with the single-table league phase that replaced the Champions League groups is instructive: football arrived at one table with unequal schedules, basketball arrived at one table with identical ones.
Why the EuroLeague standings ignore overtime points
Here is the sentence in the bylaws that almost nobody quotes, and it is the most interesting thing in the whole tie-break article: all points scored in overtime will not be counted in the standings nor for any tie-break situation.
The standings themselves are ordered by victories, not by a points-for-a-win system. Two clubs level on wins are separated by the published sequence, and that sequence is worth understanding because it decides home advantage in a best-of-five series, which is worth more than any single regular-season result.
Where the tied clubs have already met twice, home and away, the first criterion is the head-to-head record between them. If they split it, the tie goes to the score difference in the games between them. Only if that is level does the procedure widen out to overall score difference across the phase, then total points scored, then a points-for divided by points-against average computed game by game.
Where more than two clubs are tied, the same logic runs on the mini-table of games among them alone, and the rules are careful about what happens when the tie partially resolves. If applying a criterion leaves some clubs still level, the procedure restarts from the top for the clubs that remain, and if it drops to exactly two clubs the two-club sequence takes over from the beginning. Ties are unwound in layers rather than resolved by one sweep of a spreadsheet.
Two prior rules sit above all of that. A club sanctioned with the loss of a game, or with points or victories deducted by the disciplinary bodies, takes last place among any clubs it is tied with, whatever the head-to-head says. And where the tied clubs have played different numbers of games, the club with fewer games is ranked higher.
Now go back to the overtime clause and think about what it does. In a competition where score difference is the first real separator after head-to-head, counting overtime scoring would reward the accident of a game going long. Two clubs that win by four in regulation are equal; if one of them had to survive an extra five minutes and won by nine, the raw margin flatters it for no reason connected to its quality. Stripping overtime scoring out is a small, deliberate correction, and it means a EuroLeague box score and the EuroLeague standings can legitimately disagree about how much a team scored.
The EuroLeague format explained in one sequence: round 38 to the trophy
Four phases, in order: regular season, Play-In Showdown, playoffs, Final Four. The bylaws name them in exactly that order and define each pairing explicitly, which is why the bracket has no discretionary element at all. Nothing is drawn. Nothing is reseeded. Every meeting is determined by finishing position.
- Round 38 endsThe twenty clubs are ranked by victories in one table, with ties resolved by the published sequence starting from head-to-head record.
- Places 1 to 6 qualify outrightThey carry their seeding into the quarter-finals and play no extra games. Places 11 to 20 are eliminated on the spot.
- Places 7 to 10 enter the Play-In ShowdownThree single games over four days, each one hosted by the club that finished higher in the regular season.
- Play-In A: seventh against eighthThe winner takes the seventh playoff seed immediately. The loser gets one more chance and drops into Play-In C.
- Play-In B: ninth against tenthThe loser is eliminated and finishes tenth. The winner survives to play a second single game inside three days.
- Play-In C: loser of A hosts winner of BThe winner takes the eighth playoff seed. The loser finishes ninth and the competition is over for both eliminated clubs.
- The quarter-finals, best of five1 plays the winner of Play-In C, 2 plays the winner of Play-In A, 3 plays 6 and 4 plays 5. First to three wins.
- The Final FourThe four series winners meet at a neutral venue: two semi-finals on the Friday, the championship game on the Sunday, no third-place game.
The pairings are fixed in the EuroLeague Competition Rules. Play-In games are single games; every playoff tie is a best-of-five.
The Play-In Showdown is not the NBA play-in, and the difference is the seeding
Both competitions take four clubs and turn them into two qualifiers, and both use single games hosted by the higher finisher. That is where the similarity stops.
The EuroLeague pairings are A, B and C. Play-In A is seventh against eighth. Play-In B is ninth against tenth. Play-In C is the loser of A against the winner of B. The winner of A becomes the seventh seed; the winner of C becomes the eighth.
The consequence is a genuinely uneven ladder. A club that finishes seventh needs one win from a possible two games, at home in both. A club that finishes tenth needs two wins in two games, both away, against clubs that finished above it, in the space of three days, and its reward is a best-of-five against the club that topped the table.
Set that against the four-team bracket the NBA runs in each conference and one design difference stands out. The NBA play-in decides the seventh and eighth seeds, and the eighth seed then meets the first seed in a seven-game series. The EuroLeague does the same thing with a shorter series and a much longer regular season behind it. Thirty-eight games of double round robin is a far better measure of a club than eighty-two games of an unbalanced NBA schedule, so the EuroLeague is throwing away more information when it lets a tenth-placed club into the bracket. That is a choice, not an oversight. The competition has decided that four clubs still playing for something in April is worth more than the extra precision.
The scheduling is tight by design. For 2027 the Play-In Showdown is set for Tuesday 20 April and Friday 23 April, with the playoffs starting on Tuesday 27 April. A club coming through Play-In B and Play-In C plays two elimination games away from home and then opens a best-of-five on the road four days later.
Best-of-five, and the 2-2-1 that quietly decides most series
The eight qualifiers meet in four best-of-five quarter-finals. The bylaws are specific about the home split: games one and two are played on the court of the four highest-placed clubs, games three and four on the court of the next four, and game five, if it is needed, back at the higher seed. First to three wins.
The pairings are fixed. Playoff A is first against the winner of Play-In C. Playoff B is fourth against fifth. Playoff C is third against sixth. Playoff D is second against the winner of Play-In A.
The 2-2-1 pattern is not the same animal as the 2-2-1-1-1 used in a seven-game series, and the difference is bigger than it looks. In a best-of-five with this split, the higher seed hosts three of the five possible games, and crucially it hosts the two that open the series. Win both and the lower seed must take three in a row, two of them on the road, to survive. Lose game one at home and the higher seed has surrendered the advantage the whole regular season was played to earn, because the lower seed can now win the series by holding its own court and stealing nothing.
That is why the EuroLeague regular season carries more weight than the length of the playoff round suggests. Thirty-eight games buy you two home games and a decider. In a competition where the gap between the second seed and the seventh seed is often a handful of wins, that is close to the whole margin.
For 2027 the playoffs run from Tuesday 27 April and are scheduled to finish no later than Wednesday 12 May, which is a maximum of about two weeks to play out four series of up to five games. The compression is deliberate. It keeps the Final Four inside a single May weekend rather than dragging the season into June.
The Final Four is a format choice, and it costs the best team
Four clubs, one neutral venue, two semi-finals on the Friday and the championship game on the Sunday. Semi-final A is the winner of Playoff A against the winner of Playoff B; semi-final B is the winner of Playoff D against the winner of Playoff C. For 2027 the competition has the semi-finals on Friday 28 May and the championship game on Sunday 30 May.
There is no third-place game. The bylaws settle the final standings instead: the champion is first, the beaten finalist second, and the two losing semi-finalists take third and fourth ranked by where they finished in the regular season. Fifth to eighth are the beaten quarter-finalists, again ordered by regular-season position and playoff seed. The loser of Play-In C is ninth, the loser of Play-In B is tenth, and eleventh to twentieth are the clubs eliminated at the end of the regular season, in table order.
One further clause is worth knowing if you ever buy a ticket. If a club from the host area reaches the Final Four, it is treated as the home team in every game it plays, except when two such clubs meet each other. And every participating club has a minimum of 600 tickets reserved for it, which it may not resell without permission and must hand back if it cannot shift them.
Now the part that matters competitively. A one-off semi-final is a far weaker filter than a series, and the arithmetic is not close.
Take a constructed example, with round numbers chosen to make the point rather than to describe any real club. Suppose a team is good enough to win any single game against its opponent seven times in ten. Over a best-of-five, the chance it wins the series is a shade under 84 per cent. Over two consecutive single games, which is what the Final Four asks, its chance of lifting the trophy is 0.7 multiplied by 0.7, or 49 per cent. The same team, the same edge, and the format has taken it from an overwhelming favourite to a coin toss.
Make the team a weaker favourite, winning six single games in ten, and a best-of-five still gives it roughly 68 per cent. Two one-off games give it 36 per cent.
Nobody involved is confused about this. The Final Four is not there because it identifies the best club more reliably than a series would. It is there because a neutral-venue weekend with four sets of travelling supporters is the single most sellable event European basketball owns, and because a competition whose clubs are also its shareholders has an obvious reason to protect the property that pays them. The sporting cost is real and it is accepted. Anyone who has watched a club dominate thirty-eight games and lose on a Friday evening in May has seen the invoice.
How a club without a long-term licence gets in
There are four routes, and only one of them is won on the floor.
The EuroCup champion receives a one-year EuroLeague licence for the following season. This is the promotion mechanism, and it is the reason the EuroCup matters beyond its own trophy. For 2026-27 the EuroCup regular season runs from late September to mid-January in four groups of eight, with the top sixteen clubs overall going into a knockout that is best-of-three at every round: eighthfinals in February, quarter-finals in March, semi-finals at the turn of the month and finals through late April. Win five best-of-three series and you have a season in the EuroLeague.
The EuroLeague champion is granted a one-year licence for the following season if it is not already a Licensed Club. This closes an obvious hole: a wild-card club could otherwise win the competition and then have no right to defend it.
The bridge licence is the least known of the four. The bylaws grant a one-year licence to the club that originally qualified as EuroCup champion or EuroCup runner-up and then finished highest among the top eight of the EuroLeague standings. If no such club exists, the licence goes to the EuroCup runner-up instead. The rules cap this at a maximum of two seasons, which tells you exactly what it is for: it stops a promoted club from being sent straight back down after one good year, and gives it a second season to establish itself.
Wild cards cover everything else. When a vacancy arises among the Associated Club places, the Shareholders Executive Board proposes a substitution to the General Assembly, which grants it to whichever club it considers appropriate, at its own discretion. That phrase, at its own discretion, is doing a great deal of work, and it is the clause that produces most of the annual argument about who got in and why.
In every case the club still has to meet the Associated Club requirements: the contract, the registration fee, the financial and legal declarations, participation in its domestic championship, and compliance with the financial regulations. Qualifying on the court is necessary and not sufficient.

The rules on the floor are FIBA's, with a EuroLeague appendix
Article 23 of the competition rules is short and consequential: the Official Basketball Rules as approved by FIBA apply in all games, except for the modifications approved by the General Assembly. So the game itself is the international one, four quarters of ten minutes, a 6.75 m three-point arc, five personal fouls and out. If you want the full comparison with the American version, the differences between the FIBA and NBA rulebooks run deeper than most people assume, and several of them change how a possession is actually played.
The EuroLeague's own modifications are collected in an appendix, and two of them are genuinely interesting because they borrow from the NBA rather than from FIBA.
The first concerns jump balls. Under FIBA rules a held ball is resolved by alternating possession, with an arrow at the scorer's table that flips after each use. The EuroLeague throws that out. Its appendix restores the jump ball: the ball goes up in the circle nearest to where the held ball occurred, between the two players involved, and the shot clock holds at its current value unless a new team gains possession, in which case it resets to 24 or 14. For every other jump ball situation the toss is between any two opponents. This is the American procedure grafted onto a FIBA competition, and it exists because the arrow is an anticlimax that decides possessions by bookkeeping.
The second concerns television. The first time-out a club takes in any quarter is treated as a TV time-out and charged to the club that called it. If neither side has called one by the time the clock shows 4:59, a TV time-out is granted at the first dead ball and charged to nobody. All TV time-outs last sixty seconds and there are none in overtime.
Three smaller modifications are worth knowing. A player's technical foul does not count as a team foul, which is a meaningful softening of the FIBA penalty structure. A coach or team member who steps onto the court and interferes with a fast break is automatically disqualified. And bench players who enter the court during a fight can escape disqualification if replay clearly shows they took no part and were helping the referees restore order, with the FIBA rule applying in full if the replay system is unavailable.
The replay rules themselves cover the situation that most often decides a EuroLeague game in the last minute. The referees may review whether a goaltending or basket interference violation occurred, but only after one of them has already made that call on the floor, with a single exception: where a foul has been called in the act of shooting, they may check the footage for a goaltending or interference violation anyway. That asymmetry is exactly the same shape as the one in the American game, and the reason for it is the same. If you want the mechanics of why that particular call is the hardest in the sport, the line between goaltending and basket interference is where officiating in both codes does its most difficult work.
What the format is actually selecting for
Strip out the bracket and the competition is making three trade-offs, all of them visible in the rules rather than in anyone's public statements.
It trades sporting access for financial stability. A closed licence system with twenty places and a hard cap on how many clubs any one country can hold long-term gives broadcasters a guaranteed set of matchups years in advance. It also means a club can build a genuinely European brand without the annual risk of being outside the competition. The price is that domestic excellence buys you nothing directly, which is the objection that has followed the format since it was designed and which will not go away, because it is correct. Anyone who finds this arrangement strange should look at how the same argument plays out elsewhere, because the tension between a promotion pyramid and a closed franchise league is the oldest structural disagreement in professional sport.
It trades postseason precision for jeopardy. Thirty-eight games is a serious sample. A best-of-five is a reasonable filter. A one-off semi-final is neither, and the competition uses it anyway because the Final Four is the product. The constructed figures above put a number on what that costs the best club, and the number is large.
And it trades player workload for calendar tidiness. Twenty clubs playing thirty-eight midweek games while also playing a full domestic season is a lot of basketball for squads capped at sixteen registered players. That pressure is why the competition's own governance keeps returning to the calendar, and it is why the international windows that feed Olympic and World Cup qualification sit so awkwardly alongside it. There is no version of the European season in which the clubs, the domestic leagues and the national federations all get what they want.
Four things to check when the season starts
If you follow one club rather than the competition, these are the four items that will tell you more than any preview.
The licence type. Whether your club is a Licensed Club or an Associated Club decides whether the season is about the table or about survival. A one-season club is playing for a renewal as much as a seeding, and the two do not always point the same way.
The head-to-head fixtures against the clubs nearest you in the table. With score difference in the games between tied clubs sitting so high in the tie-break sequence, a nine-point home win over a direct rival in November is worth more than a twenty-point win over a club that finishes fifteenth. The competition's own procedure says so explicitly.
Where the sixth and seventh places sit in February. The whole shape of a club's spring turns on that line. Sixth means a fortnight off and a best-of-five. Seventh means an extra elimination game before the same series, against opposition that has had a week to prepare.
Whether the club is in the top four when the regular season ends. Home advantage in a best-of-five is the two opening games and the decider, and in a competition this tightly packed it is often the whole difference between a Final Four weekend and a quiet May. The full published standings and the tie-break arithmetic are on the competition's own pages, and the rest of our basketball rules and format coverage sits alongside them.
Common questions
How many teams play in the EuroLeague?
Twenty. The Euroleague Commercial Assets bylaws state that ECA will grant twenty licences to operate teams in the competition, and the 2026-27 regular season is a round robin among those twenty clubs. The identity of the twenty changes from year to year at the edges, but the number is fixed by the licensing rules rather than by results.
How do you qualify for the EuroLeague?
Mostly you do not qualify, you are licensed. Clubs holding a long-term Licensed Club licence are in by contract, and the remaining places go to Associated Clubs on a one-season licence or a wild card. The sporting route in is the EuroCup, whose champion receives a one-year EuroLeague licence for the following season.
What is the EuroLeague Play-In Showdown?
It is the three-game round that turns four regular-season finishers into two playoff qualifiers. Seventh plays eighth in a single game, ninth plays tenth in a single game, and the loser of the first meets the winner of the second in a decider. Every game is hosted by the club that finished higher in the regular season.
Is the EuroLeague playoff a best-of-five?
Yes. Each quarter-final is decided by the first club to win three games, with games one, two and five at the higher seed's arena and games three and four at the lower seed's. The four series winners go to the Final Four.
Is there a third-place game at the EuroLeague Final Four?
No. The Final Four is two semi-finals and a championship game, with no play-off for third. The bylaws rank the two beaten semi-finalists third and fourth according to where they finished in the regular season.
Can a club be relegated from the EuroLeague?
Not in the ordinary sense. A club can lose its place by losing its licence, which the bylaws allow ECA to cancel or suspend for defined reasons, and a one-season Associated Club can simply not be renewed. Finishing last does not automatically send anyone down, because there is no division below to send them to.
