not gonna lie... this thing got me pretty frustrated. : you're gonna need the picture in the link (print it or copy it on a piece of paper, it's pretty easy to draw. http://aycu37.webshots.com/image/10476/2004406912463755374_rs.jpg - The letters A-P are to be arranged in the diagram, with one letter allocated to each point, so that no two consecutive letters are connected by any direct line (i.e: 1-15 pr 7-10). - F is to the left of, and in the same horizontal line as I, which is above C. - H and D are both somewhere left of B though not necessarily in the same line. - P is somewhere higher than J, O somewhere higher than F, H somewhere higher than M and L somewhere higher than E but not necessarily in the same line. - B is diagonally adjacent to G and A is diagonally adjacent to C. - N is the greatest distance possible from O. - L is immediately left of I, G immediately left of K, J immediately left of C and D immediately left of O. If the positions of the letters E and F add up to 17, can you place each letter in its correct position? post your solution as 1=X, 2=X, 3=X, etc. how long it took you and what method you used (white font would be cool so that no one accidentally reads the answer) I got it from this book called "FANTASTIC 500 PUZZLE CHALLENGE." It's pretty cool, there's puzzles easy enough for kids or 5 minutes at the "throne" (connect the dots, spot the difference), and there's puzzles so frustrating they make me want to stab my eyes out.
