Sorry. I just turned on my PC to send you the file, and I just got the anwser.
Anyway, I was insanely confused about why the game grouped 6778, even though 6778 is neither a sequence or a triplet. But it was a representation of the closed part of the hand. (Yes, it bugged me for a whole day now.)
@LukeAlmighty Oh, well what is it?
