Softball is played on a large grass and dirt field with four bases forming a diamond. There are nine defensive positions consisting of infielders like the pitcher, catcher, and basemen and outfielders like the left, center, and right fielders. The game involves two teams alternating between batting and fielding, with the fielding team trying to record three outs before switching roles. Key elements of softball include terms like hits, runs, walks, strikes, outs, and various defensive plays.
