The Family Crossword
Everyone adds a few clues only they can answer: the village a grandmother grew up in, Dad's first car, what the youngest used to call the moon. The page fits them into one grid. Nobody can finish it alone, so everybody has to ask.
Answers can be in any language; accents are dropped in the grid (Đông Ngạc becomes DONGNGAC). The whole puzzle travels in the link after the #, so it never reaches our server. Nothing is stored.
