"Field Goal", unlike some of the other games included in Wikipedia's entry for the game "Circus" (which I'm reviewing based on its status as a Breakout clone), actually is a fairly relevant depiction of the Breakout game. Unlike catching a man on a trampoline to vault him up, in "Field Goal", you use a paddle to hit a football and this football is used to hit flying helmets. Depending on the color of the helmet and how high it is, you get a certain number of points. In addition, after a certain number of points are accumulated, a football player comes out and runs around. Hitting him will give you a multiplier and increase your points. It will also lead him into doing some kind of celebatory dance.
Like some games of this era, it is a minor variation of another pioneering game and therefore one can lose interest in it very quickly. I still found it interesting, only because Taito would later go on to make "Arkanoid", which was a stellar "Breakout" clone that added a lot of new features and bells & whistles. The Breakout genre is still pretty popular today, and developers that come out with Breakout-type games owe a large debt to Taito and their "Arkanoid" games.
