Softball is a variant of baseball played with a larger ball on a smaller field. It was invented in 1887 in Chicago as an indoor game. There are two main types: fastpitch softball, which requires years of practice for pitching and positions players, and slowpitch softball, which is more relaxed and allows 10 players. A fastpitch softball game is played between two teams on a field with four bases laid out in a diamond shape. The objective is to score more runs than the opposing team by hitting a pitched ball and running around the bases.
