From the box: "Head on baseball, an audio cassette boardgame is a whole new ballgame! You are the manager. You make the key decisions and a radio announcer calls the play by plays. It's real baseball strategy, with the excitement of hearing the highlights broadcast on the air." This is a 2 player game that roughly simulates a game of Baseball. There are 30 batter cards (15 each team) and 24 pitcher cards (12 per team). The cards have a red tinted window that line up 'decoder style' to reveal the outcome of the at bat. Periodically the outcome will be "xx tape xx" which means to activate the audio cassette tape included and listen to the "play by play action". The announcer will then tell you the outcome of the play. The rules suggest not rewinding the cassette tape until reaching the end of the tape, thus keeping some level of randomness. There are about 200 calls on the tape prerecorded.
