As per the title, all I can do is try to describe this game.
It was a dungeon exploring game. The unit was probably at least 1 foot by 1 foot in size. You would move a little 'something' (probably just a dot) around the board. And I believe you had these wall pieces that you would put up as you tried to find your way to the center. I remember it having something to do with a dungeon, although really it sounds to me now like a maze game. There was something to do with a dragon in the middle that you were trying to get to. I remember it being very hard but I was a kid back then. This game would have been made in the 80's.
Sound familar to anybody? Anybody at all? I don't think I made this up.
