In Scotland it was always called ‘guising’ (as in disguising) and we used to ‘dook for apples’ (bob for apples) and carve neeps (turnips) instead of pumpkins. I also remember a game of a treacle treat dangled on string that you had to eat with no hands but that was an old one with my grandparents.

Also it used to have to be something scary; wolves, witches, vampires, monsters. Now it’s essentially fancy dress.
