..so although it took me five minutes, I'm not sure if that's an accurate time or if concentrating on it for a few minutes dredged up the memory from my subconscious. What finally gave me the solution this time -- triggered the memory or whatever -- was that I got a very helpful zero-petals roll fairly quickly (after ten or so trials). That plus the non-utility of all the other solutions I thought of from one roll to the next did it. If you haven't gotten it yet, play again till you get a zero-petals roll :-).
