Reception.
John L. Vogel reviewed the game for "Computer Gaming World", and stated that "This is the kind of game you can introduce to a visitor with only a couple of minutes instruction, as well as play yourself on a continuing basis. If you find yourself stuffing too many quarters into arcade machines, this is a fairly good alternative."
