Football

Football is a team sport in which players attempt to score goals by passing and dribbling the ball down the field past opposing defenders and kicking or heading the ball into the goal net, outwitting the defending goalkeepers.
At the beginning of the game, choice of ends and the kick off is decided by the toss of a coin. The team winning the toss will have the option of choice of ends or the kick off. The referee having given a signal the game is started by a player taking a place-kick (i.e. a kick at the ball while it is stationary on the ground in the centre of the field of play) into his opponents half of the field of play. Every player is in his own half of the field and every player of the opposing team of the kicker remains not less than 10 yards from the ball until it is kicked off. The kicker will not play the ball a second time until it has been touched or played by another player.
After a goal is scored, the game is restarted in like manner by a player of the team losing the goal.
After half-time, when restarting, ends is changed and the kick off is taken by a player of the opposite team to that of the player who started the game.

Time is extended to permit a penalty kick taken at or after the expiration of the normal period in either half.

Cricket

Cricket is a ball game played by two teams consisting of eleven players on a pitch with two sets of three stumps (wickets). The bowler bowls the ball down the pitch to the batsman of the opposing team, who must defend the wicket in front of which he stands. The object of the game is to score as many runs as possible. Runs can be scored individually by running the length of the playing strip, or by hitting a ball which lands outside the boundary (six runs) or which lands inside the boundary but bounces or rolls outside (four runs). The opposing team will bowl and field, attempting to dismiss the batsmen.

Each team plays under a captain. The captain should nominate his players before the match. The order in which the teams bat is determined by a coin toss. The two captains of each team will toss for the choice of innings before the match. The captain of the side winning the toss may elect to bat or field first. Once the winner of the toss notify his decision to bat or to field to the opposing captain thereafter the decision shall not be altered. All eleven players of the fielding team go out to field, two players of the batting team go out to bat. The remaining of the batting team wait off the field for their turn to bat.

A match consists of one or two innings and each innings ends when the specified number of overs ( a series of six balls bowled) have been played, or when the captain of the batting team "declares" ending the innings voluntarily. Innings is a division of a game during which a side is in or batting.

What kind of sports avaialble

Sports, athletic games or tests of skill undertaken primarily for the diversion of those who take part or those who observe them. The range is great; usually, however, the term is restricted to any play, pastime, exercise, game, or contest performed under given rules, indoors or outdoors, on an individual or a team basis, with or without competition, but requiring skill and some form of physical exertion.

Some sports, such as hunting, fishing, running, and swimming, derive from the rhythms and work requirements of primitive everyday life. Some, such as riding, shooting, throwing the javelin, or archery derive from early military practices. Still others, like boxing, wrestling, and jumping, arose from the spontaneous challenges and occasional hostilities that accompany human interaction.
