I mean for the puzzle to not count any clicks for playing actions or treasures. This is purely after you click buy on some card, and before you click buy on another card. I'm pretty sure my last statement wasn't ambiguous, but to be clear, it's in reference to one "on-buy" and all the subsequent "on-gains" associated with it.
of course if you wanted you could count the maximum click-length of one turn, but that just seems painful.
