I have a memory as a child of a birthday party – I must have been 4 or 5 years old at the time – where my parents played this game, which I have never forgotten. For the game, they led each of us children into the living room but, before we entered, would put a blindfold on us. We played the game one at a time, and when in the room, my parents would then give instructions to get to the other end of it without banging into or being trapped by the obstacles on the floor.
