I agree it is more fun working it out for yourself so a clue that points you in the right direction is preferable to a direct answer. Anyway, although I have been stuck on my last 3 for some time now, I will not be seeking assistance and neither will I be offering clues until closer to the closing date.
However, this IS a question and answer site so you cannot really criticise others for asking for answers or for giving answers. You can however state your own position on the matter as I have just done.
