The Hundred Explained — Rules, Teams and the Debate

The Hundred is a hundred-ball cricket competition run by the England and Wales Cricket Board, contested by eight city-based teams, with men's and women's tournaments played as a single event. It began in 2021, a year later than planned because of the pandemic, and it has been the most divisive thing in English cricket since the two-division County Championship.

Most of the arguments about it are conducted by people who have already decided. What follows tries to set out what the competition actually is, how its rules differ from Twenty20 in ways that matter on the field, why the ECB was determined to build it, and where the objections have force. The competition has been a commercial success and a cultural irritant simultaneously, and both of those things are worth taking seriously.

What The Hundred actually is

Each side faces 100 balls. That is the headline and, in playing terms, the least significant part of it. A hundred balls is sixteen and two-thirds overs, so the innings is roughly a sixth shorter than a Twenty20 innings. Scores are correspondingly lower. A good total is closer to 160 than to 190.

The genuinely novel elements are structural.

Balls are bowled in sets of five. The over as a unit of five is not used in the scorecard presentation; the scoreboard counts balls remaining rather than overs.

A bowler may deliver five or ten consecutive balls from the same end. This is the biggest tactical departure. A captain can give a bowler a double set, ten balls in a row, before the ends change. That allows a fast bowler to work a batter over across ten deliveries with no reprieve, or a spinner to bowl two sets through a left-hander in the middle phase. Nothing in T20 permits it.

Ends change every ten balls, rather than every six.

Each bowler is limited to twenty balls across the innings, the equivalent of a four-over spell in T20.

The powerplay lasts twenty-five balls, during which only two fielders may be outside the thirty-yard circle. After that the usual limit applies.

Each side has one strategic timeout of up to two and a half minutes, called by the fielding captain. In practice it is used to reset a bowling plan when the batting side has taken control, and it is also, transparently, a television advertising slot.

How it compares to a T20

	Twenty20	The Hundred
Balls per innings	120	100
Unit of bowling	6-ball over	5-ball set
Consecutive balls per bowler	6	5 or 10
Max per bowler	24 balls (4 overs)	20 balls
Powerplay	36 balls (6 overs)	25 balls
Change of ends	Every 6 balls	Every 10 balls
Typical competitive total	170-190	150-170

The differences look small on paper and are larger in effect. The shorter powerplay proportionally rewards openers who attack immediately, because there are fewer balls in which to cash in. The twenty-ball cap means a captain has five bowlers minimum and usually six, so a specialist who can only be trusted for one set has more value than in T20. And the ten-ball option changes the risk calculation for a batting side, because a set that goes badly costs twice as much.

The eight teams

The eight sides are city-based, not county-based, and each plays at a major ground already used for international cricket.

Team	Home ground	City
Birmingham Phoenix	Edgbaston	Birmingham
London Spirit	Lord's	London
Manchester Originals	Old Trafford	Manchester
Northern Superchargers	Headingley	Leeds
Oval Invincibles	The Kia Oval	London
Southern Brave	Utilita Bowl	Southampton
Trent Rockets	Trent Bridge	Nottingham
Welsh Fire	Sophia Gardens	Cardiff

Squads are assembled through a draft and retention process combining England internationals, county professionals and overseas players. Every team fields a men's side and a women's side under the same identity, and the two play as double-headers at the same venue on the same day on a ticket that covers both.

That last point is the single most consequential design decision in the competition. Women's domestic cricket in England had never before been staged in front of full houses at Test grounds with live free-to-air television. The women's tournament is not a support act bolted on; it is structurally equal in the schedule and it has visibly moved the professional women's game forward.

How a season is structured

The tournament runs for roughly a month in high summer, occupying the school holidays, and it is short by design. Each team plays every other team in a single group phase, with a small number of additional fixtures to balance the schedule, and then the competition resolves in a knockout that takes days rather than weeks.

The side finishing top of the table goes straight through to the final. The sides finishing second and third meet in an eliminator, and the winner of that goes on to face the table-toppers. Both the eliminator and the final are played as men's and women's double-headers on the same day at the same venue, and the final has been staged at Lord's, which gives the competition a genuine showpiece rather than a rotating one.

The compression matters. A four-week window means no team can afford a slow start, injuries cannot be absorbed, and an overseas player who arrives late has missed a quarter of the campaign. It also means that a squad assembled through a draft has almost no time to become a team, which is why the sides with continuity of coaching and retained players have tended to do best. Compared with the county T20 Blast, which stretches across most of the summer, The Hundred asks a squad to peak immediately and then disband.

Why the ECB built it

The stated reasoning was blunt. Research commissioned before launch found that a substantial portion of the British public did not follow cricket and did not intend to, that the sport's audience was ageing, and that since live English cricket disappeared behind a paywall after 2005, a generation had grown up without casual exposure to it. The counter to that is that the 2005 Ashes, the last series shown live on terrestrial television, produced the biggest cricket audiences in modern British history, and the sport then sold the rights away. The Hundred is, in part, an attempt to buy that audience back.

Three specific objectives sat behind it.

Free-to-air television. A share of matches is broadcast live on the BBC alongside the Sky coverage. That was the first live domestic cricket on terrestrial TV in England for many years, and it was the point of the exercise as much as anything on the field.

A family audience. Ticket pricing, match timings, ground presentation and the deliberate simplicity of the format were all aimed at people attending a cricket match for the first time. Telling a newcomer that a bowler bowls six balls from one end and then someone else bowls six from the other end, and that this is called an over, is harder than it sounds. Telling them each side gets a hundred balls is not.

The women's game. Equal billing, equal venue, one ticket. The ECB could have achieved parts of this within the existing T20 Blast and chose not to, which is one of the fair criticisms, but the outcome has been real.

There was a fourth objective the ECB was less vocal about: a new revenue stream that the board controls centrally rather than one distributed through eighteen county boards. That has since been realised. In 2025 the ECB sold equity stakes in the eight teams to outside investors, several of them connected to Indian Premier League franchise ownership and to American technology and sports money. The sale raised a very large sum by the standards of English cricket, and a substantial share of it flowed to the counties.

The case against

The objections are not all reactionary, and dismissing them as such is lazy.

The calendar was already full. England had a four-day County Championship, a fifty-over competition and a T20 Blast. Adding a fifth competition meant something had to move, and what moved was the Championship, pushed towards April and September where the cricket is poorer and less relevant to Test preparation. Our County Championship guide sets out that argument in full. This is the strongest objection and it has never been properly answered.

The Blast already existed. England had a successful, well-attended, county-based T20 competition with genuine local rivalries built over two decades. The Hundred competes with it for players, attention and midsummer dates. Investing the same money and marketing in the Blast was a live option and was rejected, largely because the counties would have controlled it.

City franchises have no roots. A Yorkshireman supports Yorkshire because his father did. Northern Superchargers were invented in a meeting. Loyalty of that kind takes decades to build and cannot be commissioned, and the competition's crowds are better explained by ticket prices and school holidays than by allegiance.

The format is a solution to a problem nobody had. Twenty20 is already short, already simple and already understood worldwide. The five-ball set is an English invention that no other cricket nation has adopted, which means players learn a set of tactical habits that transfer nowhere else. The counter-argument, that the ten-ball spell is genuinely interesting, is true but modest.

The claim that it grew the game is difficult to test. England's white-ball transformation began after the 2015 World Cup and produced the 2019 World Cup win two years before The Hundred existed. Attributing English white-ball strength to the competition gets the chronology backwards.

What it has changed on the field

Setting the politics aside, some things about the cricket itself are now clear.

The ten-ball spell has become a real weapon. Bowlers with pace and a plan against a specific batter get a sustained crack at them, and captains hold a strike bowler back for it in the way a football manager holds a substitution. Left-arm spinners have done well, partly because the middle phase is short and partly because two sets through a right-hander is enough time to set something up.

The shortened powerplay has pushed teams towards openers who can strike from the first ball, and it has reduced the value of the accumulator who bats through. A side chasing 160 off 100 balls does not have the overs to rebuild after losing three early, so the risk profile is compressed at both ends.

Fielding restrictions and the twenty-ball cap have also raised the value of the sixth bowling option. England players who came through the competition are visible across the global circuit now, in the Indian Premier League and the Big Bash League, and English white-ball specialists such as Jos Buttler, Liam Livingstone, Adil Rashid and Sam Curran have moved between all three without visible difficulty. Whatever else The Hundred is, it has not damaged anyone's technique.

An honest verdict

The Hundred is a competent tournament that solved a real distribution problem with an unnecessary rule change. The free-to-air coverage was overdue. The women's tournament is the best thing English cricket has done in twenty years. The equity sale has, for the moment, secured the finances of clubs that were not secure.

Against that, the calendar damage to four-day cricket is genuine and has not been repaired, and the argument that a hundred balls is meaningfully easier to understand than a hundred and twenty has always been weaker than its advocates claim. Had the ECB put the same television deal, the same women's parity and the same midsummer window behind the existing T20 Blast, English cricket would probably be in a better place and would certainly be in a less argumentative one.

None of that is going to be revisited. The competition is embedded, financed and popular with the audience it was built for. If you have not watched it, watch a double-header at Lord's or Edgbaston before deciding, and read the rest of our cricket in England guides for the context around it. On the ground itself, our Lord's history is worth a read, and for the longer form that The Hundred exists in tension with, start with the Ashes and England's greatest Test players.
