At the end of every season the snooker tour draws a line under the sixty-fourth name on a list of money. Everyone above it keeps a professional living for another year. Several players below it go to Q School a few weeks later, trying to win back a place they sometimes lost by a few hundred pounds.
That list is the world ranking. A professional's position is simply the total of the prize money he has earned in ranking events over the previous two years, added up and sorted from highest to lowest. There are no points tariffs and no weighting formula. Money from invitation events such as the Masters does not count, nor do prizes for the highest or a maximum break, and each event's money drops off the list when the same event comes round two years later. World Snooker Tour, which runs the professional circuit under the World Professional Billiards and Snooker Association, revises the official list at fixed points in the season and uses it for almost everything: seedings, invitations to the Masters, places at the Crucible and who keeps a tour card.
How snooker world rankings are calculated: the money is the ranking
Take one professional and every ranking event he has played over the last two seasons. Write down the prize money he received in each. Add it up. That figure, in pounds, is his ranking total, and his position is where that total falls among everyone else's.
It really is that literal. The official list prints the totals in pounds next to the names, and commentators talk about players being "eight thousand behind" the sixteenth place rather than so many points behind it. A player who reaches the quarter-finals of a ranking event receives the quarter-final prize money set out in that event's published prize fund, and that sum goes straight into his ranking total.
The method has one large consequence. Events are weighted automatically by how much they pay. The World Championship, with the largest prize fund on the tour, is worth far more to a player's ranking than an event whose winner receives a fraction of the money, and nobody needs to decide how many points each tournament deserves. The market decides. Promoters who put up big prize funds buy importance in the ranking system as well as the attention of players, which is exactly what the system was designed to do.
A worked example with round numbers
The figures here are invented, to show the arithmetic rather than any real season. Suppose a player has the following ranking-event earnings across two seasons:
- the last 16 of the previous year's UK Championship
- a semi-final in a smaller ranking event that season
- the second round of the World Championship at the end of that season
- a quarter-final in a ranking event in the current autumn
- first-round defeats in several other events
His total is the sum of the published prize money for each of those finishes. If that sum is greater than the totals of all but twenty players, he is twenty-first. If he then reaches the semi-final of the current UK Championship, the money for that finish is added on, and the money from last year's UK run, two years old once the new event is complete, eventually comes off. The net change decides whether he climbs.
No formula. No coefficient for the strength of the field. Just addition, and subtraction two years later.
| Element | How it is treated in the two-year total |
|---|---|
| Prize money from a ranking event | Counted in full |
| Prize money from an invitation event | Not counted |
| High-break prizes | Not counted |
| Maximum-break prizes and bonuses | Not counted |
| Money from an event two years old | Removed when the equivalent event is played again |
| Opening-match money for a seeded loser | Not counted at events such as the World Championship and UK Championship |
The last row is the one most often misunderstood, and it is explained in the section on what counts below.
The rolling two-year window and how money drops off the list
A ranking total is not a season's earnings. It is a moving window, and the window moves one event at a time.
When a ranking event is played, two things happen to the list. The new event's prize money is added for every player who earned some. And the prize money from the same event two years earlier, which until that week had been part of every total, is taken away. If the event has been dropped from the calendar, its money comes off at the equivalent point in the season instead, so that nothing stays on the list for longer than two years.
So the list is always the most recent two years of results. A player's total on the morning of a tournament contains that tournament's money from two years before, and by the evening of the final it contains the new money instead.
Falling without losing a match
This is where the system produces its strangest results. A player can drop several places in a week in which he does not play at all.
Suppose a player reached the final of a ranking event two years ago and that final paid well. This year he goes out in the first round, or does not enter, or is injured. When the event finishes, the old final money is removed from his total and almost nothing replaces it. Meanwhile the players around him on the list have added new money from the same event. He has lost nothing on the table, yet he has gone backwards.
The reverse is also true. A player who had a poor season two years ago has very little to lose when those events come round again, so every match he wins in them is close to pure gain. Commentators sometimes call this "having nothing to defend", and it explains why players returning from a lean period can climb the list quickly once their form comes back.
The defence of money is the thing to watch at the World Championship especially. The money earned at the Crucible is the largest single block on the list, and it stays there for two full years. A player who reached the final two years ago carries that money into the championship and loses it at the end of the fortnight, whatever happens. If he goes out early, his ranking can collapse in a day.
- Event playedA player reaches a stage of a ranking event and receives the published prize money for it.
- Added to the totalThe sum is added to his two-year ranking total as soon as the event ends.
- Counts at revisionsIt is included in every official revision of the list for the next two years and affects his seedings throughout.
- Same event two years onWhen the equivalent event is played again, two years later, the old sum is removed from his total.
- Replaced or notIf he earns money at the new edition, that replaces it. If he earns less, or nothing, his total falls.

What counts towards snooker rankings, and what does not
The rule is easy to state. Only ranking-event prize money counts. The exceptions and boundaries are where people go wrong.
Ranking events count. These are the World Championship, the UK Championship and the rest of the ranking calendar, many of them now played in China and the Middle East as well as in the United Kingdom and Europe. Each is designated a ranking event by the tour before the season starts, and that status appears in the calendar and in the event's regulations.
Invitation events do not count. The Masters is the best-known example. Its field is chosen from the ranking list, but its prize money goes back into nothing. The same is true of the Champion of Champions and other invitation events. A player can win several of them in a season and see no change in his position. Why the Masters keeps its prestige regardless is a story of its own, told in our guide to the Masters snooker tournament.
Break prizes do not count. Many events pay a prize for the highest break of the tournament, and there are separate prizes and accumulating bonuses for maximum breaks. These are paid on top of the round money and are deliberately excluded from the ranking total. The logic is that a ranking measures how far a player goes in tournaments, and a single big break, however impressive, is not progress through a draw.
The rule on seeded players who lose their opening match
Most of the major ranking events now use a tiered structure. The lowest-ranked players start in the first qualifying round, and the top seeds enter later, sometimes not until the final stages at the venue. That creates a fairness problem. A seed who enters in a later round and loses his first match receives the prize money for the round he lost in, which is often more than a lower-ranked player earns for winning two or three matches to reach the same round.
The tour's answer has been to exclude that money from the ranking total. A seeded player who loses his opening match at the World Championship or the UK Championship is paid it in full, and it does not count for ranking purposes. The WPBSA's own rankings guidance lists that exclusion alongside two others: invitation prize money, and the money paid to first-round losers at the Shoot Out, whose single-frame format would otherwise hand out ranking money for one visit to the table. The detail of which events the seeded-loser rule covers has been revised more than once, and the wording changed again when the whole system moved from points to prize money. The effect is the important part: a player cannot climb the list simply by being seeded into rounds that pay well and losing in them.
Non-ranking prize money still matters to a player
None of this means invitation money or break prizes are worthless. They are paid in full and count in a player's earnings, which is what pays for his travel, his practice table and his entry fees. They do not count in the one table that decides seedings and tour survival.
Seeding cut-offs: when the official list is revised
A common misconception is that the official ranking changes after every match. It does not. The money is added as events are played, but the official list that the tour uses for seeding is fixed at a series of revision points spaced through the season, after particular tournaments.
Between those points, the seedings in use stay the same even though the underlying totals have moved. A player who wins an event in October may not see that win reflected in his seeding for the next tournament if the next revision point has not yet been reached. When the revision comes, the list is reissued with all the money earned since the last one, and that new list sets the seedings for the next batch of events.
Before 2010 the system was simpler and slower. The rankings were revised once a year, at the end of the season, so a player's seeding for an entire season was set by his results over the two seasons before it. The rolling list introduced in 2010 brought in several revisions a year, making the seeding reflect recent form much more quickly.
The cut-offs that commentators track
Some revision points matter more than others, because they decide entry to particular events:
- After the UK Championship. The list issued after York decides the sixteen players invited to the Masters in January.
- Before the World Championship. The list after the last ranking event before Sheffield decides the sixteen seeds at the Crucible, who go straight into the first round, and the order in which everyone else enters the qualifying rounds.
- The end of the season. The final list, after the World Championship, decides who keeps a tour card and sets the seedings for the start of the next season.
The exact events that trigger the other revisions are set out in the tour's calendar each season and change from year to year as events are added and dropped.
How the top 16 in snooker is decided, and what it brings
Sixteenth on the ranking list is the most valuable position in the sport that does not involve winning anything.
The top 16 is simply the sixteen highest totals at a given revision. There is no separate selection. Whoever is sixteenth at the relevant cut-off is in, and whoever is seventeenth is not, even if the difference is a few hundred pounds earned in a first-round match a year and a half earlier.
Two things follow from a place in the top 16 at the right moment.
The Crucible. At the cut-off before the World Championship, the sixteen highest-ranked players on the list become the sixteen seeds, in ranking order, and go directly into the first round at the Crucible Theatre in Sheffield. There is no automatic top seeding for the defending champion: he is seeded where his ranking puts him, and in 2025 the world number one was seeded first while the defending champion was seeded elsewhere in the sixteen. Everyone else, including the player ranked seventeenth, has to play through the qualifying rounds, held in recent years at the English Institute of Sport in Sheffield. The difference is a fortnight's preparation against two or three best-of-19 matches. How those qualifying rounds work is explained in our guide to World Snooker Championship qualifying, and how the seeds are placed in the draw is covered in our guide to the World Championship format.
The Masters. At the cut-off after the UK Championship, the top 16 on the list are invited to the Masters at Alexandra Palace. The defending Masters champion and the reigning world champion take the first two seedings there, but they are not extra entrants: a former champion who has dropped out of the sixteen is not invited at all.
The races to the cut-off
Because the line is so sharp, the races for sixteenth place before each cut-off are one of the season's recurring storylines. Statisticians and commentators work out which players can still reach the top 16, what each one needs, and who must lose for someone else to get in. A player sitting seventeenth before the UK Championship may need a quarter-final, or a semi-final, depending on how many of the players above him are defending big sums from two years earlier.
There is also a quieter benefit. Being in the top 16 means being among the top seeds in tiered events for the rest of the season, which means fewer qualifying matches, more time at home and a smoother route into the venue stages of tournaments. Over a season that adds up to a meaningful advantage in both money and energy.
The top 64 and keeping a tour card
At the end of each season, after the World Championship, the tour applies its qualification criteria for the following season. The single most important rule is the top 64. Every player inside the top 64 of the two-year list at that point keeps his professional status for the next season, regardless of how he came to be there.
A player outside the top 64 loses his place unless one of the other criteria saves him:
- A two-year card in its first year. New professionals and players who regained their cards are given two seasons, and the end of the first season is not a test. Only at the end of the second do they have to be inside the top 64 or qualify some other way.
- The one-year list. A small number of players who finished outside the top 64 but were among the best performers over the season just ended are given new two-year cards from the one-year list.
- Other criteria. Invitational cards and other routes exist, but they apply to few players.
Everyone else drops off the tour and becomes an amateur. For most of them the next stop is Q School, the open qualifying competition played a few weeks after the World Championship, described in our guide to snooker Q School.
Why 64 matters more than the money suggests
The prize money that separates 64th from 65th is often modest, and both players will have earned far less from the game than a top-16 player earns in a season. The line is still the difference between a professional living and none. A player on the tour can enter every ranking event. A player off it cannot, except through a small number of top-up places and invitations.
The players who finish just inside the line are almost never the ones the television audience watches. Their matches at the World Championship qualifiers, played on outside tables at the English Institute of Sport, can decide a career while the Crucible is being prepared down the road.
What is the one-year ranking list in snooker?
A second table, running alongside the official one, counting only the ranking-event money won in the current season. It starts at zero for everyone in the summer and builds up as the season's events are played.
The one-year list has two uses.
The Players Series. World Snooker Tour runs a group of three events whose fields are chosen from the one-year list rather than the two-year one, and the fields narrow as the series goes on. The World Grand Prix takes the top 32, the Players Championship the top 16 on the list as it stands after the Grand Prix, and the Tour Championship the top 12. The idea is to reward current form. A player who has had an outstanding first half of the season can get into these events even if his two-year total is held back by a poor season before.
Tour cards at the end of the season. A small number of players who are outside the top 64 on the two-year list but high on the one-year list are given new two-year cards. The number has changed more than once and is set out in the qualification criteria each season. This route exists for players who were relegated or newly arrived, started from a low total, and played well enough over the season to deserve to stay.
How the two lists disagree
The two lists can differ sharply. A player who was very good two seasons ago and has been poor this season can be comfortably inside the top 32 on the two-year list and nowhere on the one-year list. A newly promoted player can be high on the one-year list after a good run and still sit near the bottom of the official list, because he has only one season's money.
| List | Window | Main uses |

| One-year list | Ranking-event prize money from the current season only | Fields for the Players Series events, end-of-season tour cards for players outside the top 64 |
| Provisional or projected list | The two-year total with money due to expire already removed | Unofficial guide to where a player is likely to be after an event |
| Seeding list for one event | The official list fixed at the last revision point before that event | Draw and seeding for the event, unchanged during it |
Snooker provisional rankings explained
During a tournament, newspapers and websites often print a "provisional" or "projected" ranking list. It is not the official list, and it is easy to misread.
A provisional list takes the two-year totals and removes the money that is about to come off because the same event is being played again. It then adds whatever money each player has earned so far in the current event. The result shows roughly where each player would stand if the event ended now. As players win and lose matches during the week, the provisional list changes.
The point of removing the expiring money first is that the official list in the middle of a tournament still contains the money from two years ago. A player who reached the final of the event two years ago looks secure on the official list until the end of the week, but the provisional list shows his position without that money, which is much closer to where he will be.
How to read a projected list
Three things to keep in mind.
First, a projected list is a calculation by whoever publishes it, and different publishers sometimes handle edge cases differently, such as seeded players' opening-match money or events that have been dropped from the calendar. The official list issued by the tour after the revision point is the only one that counts.
Second, the figure next to a player who is still in the tournament is a minimum. If he wins his next match, he earns the money for the next round, and the projection moves.
Third, projections are most useful at the cut-offs. Before the UK Championship ends, a provisional list tells a viewer which players can still reach the top 16 for the Masters and what each needs to do. Before the World Championship, it shows who is safe inside the top 64 and who is playing for his tour card.
New professionals and the zero start
A new professional begins on nothing. Whatever he did as an amateur, however many amateur titles he has won or however well he played at Q School, his two-year ranking total starts at zero on the first day of his card.
That puts him at or near the bottom of the official list for his first season, alongside the other new professionals. In tiered events he starts in the earliest qualifying rounds, against other low-ranked players, and has to win several matches to reach the venue stages. Every pound he earns is new money with nothing to defend, which is why a strong first season can lift a new player a long way up the list, but even an excellent first season rarely takes him near the top 16, because the players there have two full years of results.
The two-year card is what protects him. A new professional cannot be relegated at the end of his first season, whatever his ranking. He has two years to build up enough money to finish inside the top 64. A player who has a quiet first year but a good second one keeps his place. A strong first year helps too, because that money is still inside the two-year window when the line is drawn, but a poor second year can leave the total short all the same.
The same start for returning players
The zero start applies equally to players who lost their place and regained it. A former top-16 player who drops off the tour and wins a card back through Q School begins the new card with the same empty total as a teenager in his first season, even though his previous career may be worth millions on paper. The ranking list has no memory beyond two years. That is the system's fairness, and also its harshness. How a player earns his way onto the tour in the first place is covered in our guide to becoming a professional snooker player.
From points to pounds: a history of the ranking system
- The World Professional Billiards and Snooker Association published the first official world ranking list, built on results in the three most recent World Championships. Ray Reardon was the first world number one. For the first years the list was a small thing, built on three tournaments and revised once a year.
For its first six seasons the list rested on the World Championship alone. That changed in 1982-83, when the WPBSA brought two open-entry tournaments into the system: the Jameson International Open at the Assembly Rooms in Derby, the first event outside the World Championship to carry ranking points, and the Professional Players Tournament that followed it. More events were added through the 1980s, and the system took the shape it kept for more than three decades. Each ranking event had a tariff of points for each round reached. The World Championship carried the most, and the other ranking events less, according to a scale set by the governing body. A player's ranking was the total of his points over the previous two seasons, and the list was revised once at the end of each season.
Steve Davis was number one for seven consecutive seasons in the 1980s and Stephen Hendry for eight in the 1990s. Under the annual system those reigns were measured in whole seasons, because the list did not move in between.
| Period | Basis | How often revised |
|---|---|---|
| 1976-77 to 1981-82 | World Championship results only | Once a year |
| 1982-83 to 2010 | Points tariffs for each ranking event, over two seasons | Once a year, at the end of the season |
| 2010 to 2014-15 | Points tariffs, rolling two-year total | Several times a season |
| 2014-15 onwards | Ranking-event prize money, rolling two-year total | Several times a season |
The changes of 2010 and 2014
The tour's new management brought in the rolling list in 2010. Instead of one revision a year, points earned in an event were added straight away and points from the corresponding event two years earlier removed, with the official list reissued at several points in the season. The change made the list far more responsive to form.
The switch from points to prize money followed for the 2014-15 season. The argument for it was that the points tariffs had become arbitrary, with each new event needing a decision about how many points it was worth and the decisions rarely satisfying everyone. Prize money did that job automatically and gave promoters an incentive to put up bigger prize funds. It also made the list easy to explain: the player who has earned the most from ranking events in the last two years is the world number one.

The criticisms of a prize-money ranking
The system has critics, and the criticisms are not frivolous.
One big cheque can outweigh several good tournaments. Because events are weighted by prize money, a single deep run in the event with the biggest prize fund can be worth more than wins in several smaller ranking events. A player who wins two smaller titles in a season can end up below one who reached a single final in a richer event. Supporters of the system say this simply reflects which events matter. Critics say it rewards one good week over a season of consistency, and the arrival in recent seasons of new events in the Middle East and Asia with large prize funds has sharpened the argument.
The world champion is often not the world number one. The World Championship is the biggest event, but winning it adds only one season's prize money to a two-year total. Luca Brecel won the 2023 world title without becoming world number one. Shaun Murphy won in 2005 as a qualifier from outside the top 16. Zhao Xintong won the 2025 title having come through four qualifying rounds as an amateur, with no place on the professional ranking list at all, although he had already secured a tour card for the two seasons that followed. Each of those champions was the best player in the sport for seventeen days in Sheffield. None was the best over two years, and the list measures two years.
It does not measure current form. The two-year list is a measure of sustained results, and it lags behind a player who is improving quickly or declining sharply. The one-year list exists partly to correct this, but the official list that decides seedings and tour survival is still a two-year total.
What the list does say
The prize-money ranking is honest about what it measures. It is a record of results over two years, weighted by the money the events paid. It says who has done most in the ranking events over that period, and nothing about who is playing best this month or who would win a single match tomorrow. Read it that way and its oddities make sense.
