Cricket: The rules for the casual viewer

Raymond Chen

The 2019 Cricket World Cup is under way. I learned cricket by reading the rules, never having seen a match. During the 2015 World Cup, I finally got to watch parts of a match on television with a colleague of mine, who patiently answered the questions I couldn’t answer from reading the rules.

This is the first in a series of sporadic entries on “the minimum you need to know about a sport in order to watch a match and not be completely confused”. We’ll see how it goes.

As I noted some time ago, most Web sites that try to explain the rules to a game get bogged down in irrelevant details, like the number of pieces of leather which are sewn together to make the ball. Let’s assume that the equipment conforms to regulations, and that the players generally follow the rules.

Given those assumptions, here are the rules for cricket for the casual viewer.

  • The object is to score more runs than your opponent.
  • Each side (team) consists of eleven players.
  • The playing area is bounded by a boundary line, and in the center is a lane (pitch) with a wooden contraption (a wicket) at each end.
  • One side is batting and the other is fielding.
  • The batting side places one batsman at each wicket. The remaining players from the batting side remain out of play.
  • The fielding side may place its players pretty much anywhere they choose.
  • One player from the fielding side (the bowler) bounces (bowls, delivers) the ball from behind one wicket toward the opposite wicket in an attempt to dislodge a piece of wood (the bails) which sits atop it.
  • The batsman assigned to the attacked wicket (the striker) wields a bat in order to defend the wicket by using it to hit (or at least block) any ball that threatens to strike the wicket.
  • Whenever the batsmen deem it safe (usually after the striker hits the ball a safe distance), they may attempt to exchange positions as many times as they wish. Each exchange scores a run. (Note that if an odd number of runs are scored, the non-striking batsman becomes the new striker.)
    • If the ball leaves the playing field, four runs are automatically scored.
    • If the ball leaves the playing field without hitting the ground, six runs are automatically scored.
  • A batsman is dismissed or out when one of the following things occurs. (This list is not complete but covers what you will normally see.)
    • Bowled: The bowled ball dislodges the bails.
    • Caught: The striker hits the ball, and a fielder catches it inside the boundary before it hits the ground.
    • Stumped / Run out: A batsman is out of his ground (not in the safe zone near each wicket), and the fielding team throws the ball and dislodges the bails. (The striker is stumped if this occurs without ever hitting the ball; a batsman is run out if this occurs when trying to exchange places after the ball is hit.)
    • Leg Before Wicket (LBW): The striker would have been bowled, except that the striker blocked the path of the ball with his body. This is a judgement call by the umpire, and consequently is a fertile source for argument.
  • For various offenses the umpire may declare a batsman out (to penalize the batting side) or award runs (to penalize the fielding side).
  • A set of six balls (an over) is bowled toward one wicket by a single bowler, and then the fielding team must change bowlers. At this time, the bowler changes ends so that the ball is delivered to the other wicket. (The batsmen do not change ends, so that the non-striking batsman becomes the new striker.)
  • When a batsman is out, he is replaced by a teammate who is not yet out.
  • After ten batsmen are dismissed, the fielding side becomes the batting side, and the batting side takes the field. (Ten is the magic number because that leaves the batting side with only one player. Batting requires two batsmen, one for each wicket.)
  • After each side gets two turns in the field and two turns at bat, the match is over, and the side with more runs is the winner.

Traditionally, a cricket match is played over five days. If five days elapse and the match is not yet finished, the entire match is declared a draw regardless of the score. A side that has the lead may choose to forfeit its remaining outs (declare) in order to try to finish the match before time runs out.

There are variations of the rules designed to shorten the length of a match. The most common variation is to limit the number of overs.


  • A no-bounce delivery is permitted by the rules, but it does not occur in practice because bouncing the ball confers an advantage to the bowler. There was also the infamous underarm bowling incident of 1981.
  • There are two general classes of bowler: fast bowlers rely on speed; spin bowlers use spin to produce a trajectory that is difficult to predict.
  • The ball starts the match smooth and hard, but becomes rough and soft as the match progresses. Fast bowlers prefer a hard ball, because it bounces faster. Spin bowlers prefer a more worn ball, because the roughness allows the ball to grip the ground better, thereby imparting more spin.
  • Bowlers rub the ball against their trousers in order to make one side of the ball smoother than the other. The aerodynamic difference between the smooth side and the rough side allows the bowler to impart more curve to the ball.
  • The rules for catches at the boundary are rather complex. You can watch these videos to get an intuitive sense for how it works. For something more boring, watch this instructional video.
  • In a game-theoretic sense, the batting team is on the offensive (since they are the ones who score runs). Psychologically, however, the batting team is on the defensive, trying to protect their wicket and avoid being dismissed.

    Not to be confused with Krikkit and the Wikkit Gate

      That elaborate joke is completely lost on us Americans.

      That was my favourite Dr. Who episode that never existed. (Slartibartfast replacing the Doctor, etc. DNA was a writer for Who at the time.)

    Excellent!Now can we have a simple description of baseball? 🙂

    Pretty good interpretation! Look forward to the (even longer?) post explaining the field positions/terminology in the game. Only the English would have come up with anything like this (a sample: long on, mid-off, cow corner, point, 3rd man, and of course, the “silly” positions).
    I prefer this, much simpler explanation of the game:
    You have two sides, one out in the field and one in. Each man that’s in the side that’s in goes out, and when he’s out he comes in and the next man goes in until he’s out. When they are all out, the side that’s out comes in and the side thats been in goes out and tries to get those coming in, out. Sometimes you get men still in and not out.
    When a man goes out to go in, the men who are out try to get him out, and when he is out he goes in and the next man in goes out and goes in. There are two men called umpires who stay all out all the time and they decide when the men who are in are out. When both sides have been in and all the men have been out, and both sides have been out twice after all the men have been in, including those who are not out, that is the end of the game!

      You think that explanation is simple?  My head exploded.  🙂

    Excellent explanation of the rules Raymond! I do hope you keep the series going – I’d love to read about American Football.
    I’d maybe throw the term Innings into this one on Cricket
    “After each side gets two turns (innings) in the field and two turns (innings) at bat”

    Not a bad description! The main thing I’d add, for people coming to it for the World Cup specifically, is that the rule changes to make a shorter game (from 5 days down to 1) also impose pretty heavy restrictions on exactly where fielders can stand (although you’re correct that it’s “pretty much anywhere” in the 5-day version of the game). 
    For example: a maximum number of people can field “outside the circle” (the circle being the inner area within 30 yards of the pitch), and this maximum changes at various points in the game, and there are also rules that you have to have at least 3 people fielding on either side of the batsman. These rules are there to favour the batting team, encouraging them to play more exciting shots.

    Yes, pretty good summary, I’d wouldn’t do nearly so well at any US sport.  The phrase “The fielding side may place its players pretty much anywhere they choose.” made me smile as it brings to mind that there are certain rules about where fielders can be placed.  These rules came about because of the Bodyline series where (in part) the placement of fielders caused a diplomatic incident between England and Australia.

    A good friend of mine is from New Zealand.  He told me about Silly Leg and Dibbly-Dobbly.  “You can field in the slips, at gully, at square leg or even at silly point” is from, although the chart doesn’t show the silly point.  And there are 11 ways to get “out” in Cricket.
    As you mention, a Test match can last for several days.  Cricket is the only sport I know of where the players break for afternoon tea.  How civilized…..
