When was the first softball game?
The first game of softball was played on Thanksgiving Day in 1887 in Chicago. George Hancock is credited with the invention of the (originally) indoor game.
According to the rules of the International Softball Federation (ISF), a perfect game in softball is a statistic credited to a pitcher when he/she completes a game and allows the opposing team no one reaching first base. By international softball rules, a game is considered complete if a team is winning by 20 runs after three innings, 15 after four, or seven after five.
