Grew up on the south side of Chicago and my best friend had this toy that I thought was called something like rottoball that was kind of like a head to head pinball/slash hockey like game. I believe that it was a light to medium green colored plastic frame enclosed with a clear plastic top, the object was to get a marble past your opponents flippers through to their goal. There were various pinball like obstacles that your marble had to manuever around to get to the other side. I am having a hard time finding the game. I think that the main stores of the time that would have sold the game would have been either toys r us, venture, or maybe montgomery wards. Need help finding this toy
