Kickball was invented in the United States around 1942 during World War 2. It is a playground and recreational game played primarily in North America and South Korea that is similar to baseball but uses a rubber ball that is kicked instead of a baseball that is hit. A kickball game is played by two teams of 9 players each on a field with 4 bases arranged in a diamond shape. Players score runs by kicking the ball and running around all the bases without getting tagged or caught out. The team with the most runs after 6 innings wins.
