Big Square Eye was a short-lived kids game show, hosted by Bob LaCastra for ABC TV from 1991-92 with future musician Paul Mac as "Knuckles" McDermott on the Sound Effects.
Each round started with a challenge being explained to the children in the audience. Then picking at random 3 kids to come and have a go at whatever it was. They would do this three times and then at the end of the show pick a player from each game and then pick an ultimate winner from those three. With the winner being granted the right to wear the Winner's Jacket and get a trophy.
