Publisher Catalog Play football against a friend or your computer with PIGSKIN. It features a graphic display of the field, the ball and scoreboard statistics. When you have the ball you choose from eleven offensive plays while your opponent picks which of the seven defenses might stop you--77 possible play options in all! The 30-second clock and a variety of penalty calls keep you on your toes. If you play against your TRS-80, there are five levels of difficulty. And they aren't easy! You can even save a game for later completion.
