Positioning Knights on Mantel in Green Drawing Room

I'm having problems positioning knights on mantel, can I PLEASE get some help!!!

Well I guess I have to find it myself, and I did.

Help...I can not get out of the "blue room" with that chess game...the one with the knight on whit queen....Help...I want to play on...any one

Ok, late to this game i suspect, but place the prism on the 'stand' on the mantle, click on the chess board to bring it up larger and place the night above the white queen. then close the chess board and click the jewel on the chessboard/table. WHEW, didn't think i'd ever figure it out. Great Game though.

how did you position the knights? i have the game on my itouch and im stuck on this part... please help!
