How to play Cricket

[Kilroy]

"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 that's 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 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 given 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!"

[Kilroy]

Here are the rules on how the people who are in get out. Below are the official rules for one of the ways to be dismissed during a batsmans innings:

Law 36: Leg before wicket
1. Out LBW
The striker is out LBW in the circumstances set out below.
(a) The bowler delivers a ball, not being a No ball
and (b) the ball, if it is not intercepted full pitch, pitches in line between wicket and wicket or on the off side of the striker's wicket
and © the ball not having previously touched his bat, the striker intercepts the ball, either full-pitch or after pitching, with any part of his person
and (d) the point of impact, even if above the level of the bails
either (i) is between wicket and wicket
or (ii) is either between wicket and wicket or outside the line of the off stump if the striker has made no genuine attempt to play the ball with his bat
and (e) but for the interception, the ball would have hit the wicket.

2. Interception of the ball
(a) In assessing points ©, (d) and (e) in 1 above only the first interception is to be considered.
(b) In assessing point (e) in 1 above, it is to be assumed that the path of the ball before interception would have continued after interception, irrespective of whether it might have pitched subsequently or not.

3. Off side of wicket
The off side of the striker's wicket shall be determined by the striker's stance at the moment the ball comes into play for that delivery.
