A bat and ball game is a sport in which players use a bat to hit a ball and then run around a field. Two popular examples of this type of game are Rounders, which originated in England and is now played in many countries, and Oneocat, which is a variation of Rounders that is popular in the United States. Both games involve teams of players who take turns batting and fielding the ball. The objective of the game is to score more runs than the opposing team.
