Softball is a team sport popular especially in the United States. It is a direct descendant of baseball and the rules of both sports are substantially similar. Softball was invented by George Hancock in Chicago, Illinois. The first softball game was played using a rolled up boxing glove as a ball and a broomstick as a bat.

Similar to baseball, softball is played between 2 teams on a large field, composed of a dirt and grass infield which contains the diamond and running areas, and a grass outfield. There are 4 bases on the infield ( the first base, second base, third base,and home plate); the bases are arranged in a square and are typically 45 to 65 feet apart. Near the center of this square is the pitcher's circle, and within the circle is the "rubber", a small flat rectangular area also known as the "pitcher's plate". The object of the game is to score more runs (points) than the other team by batting (hitting) a ball into play and running around the bases, touching each one in succession. The ball is a sphere of light material, covered with leather or synthetic. It is 10 to 12 inches (or rarely, 16 inches (28 to 30.5 centimeters) in circumference. The game is officiated by one or more neutral umpires. Players and umpires are generally free to ask for a brief stoppage at any time when the ball is not in play, or immediately following a play once its outcome is clear.

The game is played in a series of innings, usually seven. An inning is one series of both teams playing offense and defense. Each inning is divided into a top half and a bottom half indicating which team is playing which role. The offense bats and attempts to score runs, while the defense occupies the field and attempts to record outs in a variety of ways. After the defense records 3 outs, the half inning is over and the teams switch roles.

Any ball going outside the first or third base line is a foul ball ( runners can not advance and the batter gets another try unless the ball was caught in the air, which translates to an out).
