Like their earlier game Tel Tel Mahjong, it was specifically designed to work with the Sega Mega Modem peripheral - the "Tel Tel" in the title being short for "telephone". Unlike other baseball games where the player assumes direct control of the batter or pitcher, the player instead plays a more managerial role with commands and strategies that the AI players follow to the best of their abilities. This was due to the impracticality of a real-time baseball game being played over a limited-baud modem connection.
