uuummm.....each of the 4 rooms has two puzzels.if you solve the sliding puzzles in the middle of the room,you will be dumped intwo level b1 and more unknown variations will be released.The second puzzle involves the panels in the north part of the room. if you translate the word(in the alaphabet of the unown) use a related item,technique,or pokemon.you will gain access to an area with a piece of the unown story(written in unown lauguage) on the floor. if you didnt understand that explanation its okay,i got it straight from the nintindo guide.....
