In 1-player mode, the player attempts to win one game on each available field. Upon doing so, the player then faces a difficult all-female team called "The Amazons" on the professional field. Defeating the Amazons beats the game. In 2-player mode, players play an "exhibition game."
Players choose either fast-pitch or slow-pitch mode, the playing field, a team of ten players from the 60 available characters, and a team name from a list of 26 names, one for each letter of the alphabet.
Despite the game being a softball game, the rules are more reminiscent of baseball, with the exception that each game is played to a maximum of seven innings (unless extra innings are needed to break a tie). The game also features a mercy rule, with the game ending if someone leads by 10 or more runs after an entire inning is played.
