All About Cricket Rules

Game rules- 

           Cricket is a game played with a bat and ball on a large field, known as a ground, between two teams of 11 players each.
The object of the game is to score runs when at bat and to put out, or dismiss, the opposing batsmen when in the field. The cricket rules displayed on this page here are for the traditional form of cricket which is called “Test Cricket”.
However there are other formats of the game eg. 50 over matches, Twenty20 Cricket etc where the rules differ slightly. Cricket is a game played between two teams made up of eleven players each. There is also a reserve player called a “twelfth man” who is used should a player be injured during play.
The twelfth man is not allowed to bowl, bat, wicket keep or captain the team. His sole duty is to act as a substitute fielder.
The original player is free to return to the game as soon as they have recovered from their injury.
To apply the law and make sure the cricket rules are upheld throughout the game there are two umpires in place during games. Umpires are responsible for making decisions and notifying the scorers of these decisions.
Two umpires are in place on the playing field while there is also a third umpire off the field who is in charge of video decisions.
This is where the call is too close for the on field umpires and they refer it to the third umpire who reviews slow motion video replays to make a decision.

Test Cricket Rules-
    

Test cricket is played in whites.

It's a 5 day Match.

There are 3 sessions of 2 hrs each.

The break between 1st and 2nd session is of 40–45 Mins and is called as lunch.

The break between 2nd session and 3rd session is of 15–20 mins and is called as Tea.

The end of the day's play is called stumps.

Umpire dislodge the bails when a session ends.

If the team batting first score some runs, then the team batting second trails their score. If they are successful in trailing then lead starts and the team who had batted first will trail it first and then set the target. If they are unsuccessful then it's an innings defeat.

If the team which is trailing gets out when the deficit is more than 200, then the opposition team has an option to let them bat again or bowl.

If the team which was trailing and got out with a deficit of more than 200, bats again and gets out before making the required trail runs then also it's an innings defeat.

If there is no result through the entire test then the match ends in Draw.

Each day 90 overs will be bowled. If there is rain or something on any particular day and overs are lost, the very next day play will start half an hour earlier or time will distributed among sessions and 98 overs will be required to be bowled on that day.

After a period of 80 overs bowling team has an option to go for New Ball.

Standard Cricket Rules are there.

3rd Bouncer is called as No Ball.

The ball going down the leg side without touching a Batsman will be called wide if its length is pretty far from the Batsman or touching the wide line. Otherwise it would be a fair delivery.

For off stump line its the same as in ODI.

There's no free hit.

Both Teams have 2 DRS referrals for each innings while bowling and batting.

There's no D/L method here.

There is a fine for slow over rate that is if you dont bowl the minimum required overs which were required to be bowled on that day.

There is a penalty for misbehaviour and violation of code of conduct by a player.

T20 Cricket Rules-
In Twenty20 cricket, each team is allowed one innings to try and score as many runs as they can within a period of 20 overs (120 balls).
However, whilst Twenty20 shares many of the laws of the longer versions of the one-day game, it also possesses certain individual rules that are designed to speed up the passage of play. Though some cricket traditionalists have argued that these specific laws cheapen the image of cricket, they are ultimately designed to give Twenty20 a fresh and more exciting edge.

Specific rules of Twenty20 cricket

• The ‘Free Hit’ – The ‘Free Hit’ serves to penalise a bowler if he delivers a no-ball by overstepping his mark. The Free Hit is awarded following such an infringement and basically means that the batsman will not be given out for that delivery, unless he is run out. The batsman is essentially given a free swing, without fear of the repercussions.
• Five-run penalties – In Twenty20 cricket, an umpire may award one of the team’s five bonus runs if he feels the opposition is needlessly wasting time. This is designed to maintain the flow and pace of a Twenty20 match.
• 75-minute time limits – Bowling teams are forced to complete their 20 overs within 75 minutes (i.e. three minutes and 45 seconds per over). A bonus of six runs is given to the batting team if the bowling side has not begun its twentieth over before their 75 minutes is up. Once again, this rule aims to maintain the rhythm and pace of the Twenty20 game.
• Bowling restrictions of Twenty20 – In a move once more designed to favour the batting team, individual bowlers are only allowed to bowl for a total of four overs during a Twenty20 game. This obviously limits the damage that can be inflicted on the batting side by a single, in-form bowler.
• The 90-second rule – Once a wicket has fallen in a Twenty20 match, the following batsman must take up his position at the wicket or bowler’s end within 90 seconds. If they are unable to do so, they could potentially be disqualified from batting in the match.
• Fielding restrictions of Twenty20 – Twenty20 cricket laws only allow five fielders to stand on the leg side of the batsman at any one time. Similarly, only two fielders are allowed to stand outside of the inner circle in the first six overs of play. This number increases to five fielders in the remaining 14 overs. These restrictions are designed to increase the flow of runs in a match, in order to create more of a spectacle for watching fans.
• Bowl-outs – Akin to the penalty shootout in many other sport, bowl-outs take place at the end of tied Twenty20 matches. Five bowlers from each side are allowed to bowl twice at the wicket, with no batsman standing in its way. The team to topple the most wickets wins the game.

 One Day International Cricket Rules-
The game is played between 2 teams bowling 50 overs each. rest of the rules are same as that of t20 crickt. 

Extra runs-  
 “No Ball” can be declared for many reasons: If the bowler bowls the ball from the wrong place, the ball is declared dangerous (often happens when bowled at the batsmen’s body on the full), bounces more than twice or rolls before reaching the batsman or if fielders are standing in illegal positions. The batsman can hit a no ball and score runs off it but cannot be out from a no ball except if they are ran out, hit the ball twice, handle the ball or obstruct the field. The batsman gains any runs scored off the no ball for his shot while the team also gains one run for the no ball itself. 

A “Wide Ball” will be declared if the umpire thinks the batsman did not have a reasonable opportunity to score off the delivery. However if the delivery is bowled over the batsmen’s head it will not be declared a wide but a no ball. Umpires are much stricter on wide deliveries in the shorter format of the game while being much more relaxed in test cricket. A wide delivery will add one run to the batting team and any runs scored by the batsman. The batsman is not able to get out off a wide delivery except if they are stumped, run out, handle the ball, hit their wicket or obstruct the field. 

A “Bye” is where a ball that isn’t a no ball or wide passes the striking batsman and runs are scored without the batsman hitting the ball. 

A “Leg Bye” is where runs are scored by hitting the batsman, but not the bat and the ball is not a no ball or wide. However no runs can be scored if the striking batsman didn’t attempt to play a shot or if he was avoiding the ball.
