Ah, I have used only the old and new usage of ? ?????, but to be totally honest, most of them were forced by their crossing clues or else only one letter created a real word.
So, right answer but not because I understood the 1,5,3,3 - but I'll take the win anyway:-)
Many thanks Malone.
PS I never did the 1,5,3,3 as a child and I can't remember any of my friends doing it either. Hmmm 🤔
