Abstract: A game board having a representation of a baseball playing field is provided. Cards containing questions about the sport are divided into regular question and “challenge” question cards. When batting, a player uses a chance determining device to determine the outcome of an at bat, preferably either a “hit” or “out”. If the outcome is a “hit”, such player is then asked a question taken from a regular question card. If answered correctly, a playing piece is moved to the designated base. If the “hit” is a home run, a run is tallied on the scoreboard. Next, at the battling player's option, he or she may then ask an opposing player a question from a “challenge” question card. If the opposing player answers incorrectly, the battling player will advance his or her playing piece an extra base. The team with most runs at the end is declared the winner.
