On each side of the small squares, there is either the top or bottom half of a shape. There are four different shapes: horse, toy, ornament, or present.Here is a list of the small squares' shapes going clockwise.SQAURE1: horsebottom, ornamenttop, toytop, presentbottomSQAURE2: toybottom, presenttop, horsetop, ornamentbottomSQAURE3: ornamenttop, presenttop, toytop, toybottomSQAURE4: presentbottom, horsebottom, toybottom, ornamentbottomSQAURE5: horsetop, presentbottom, toytop, ornamenttopSQAURE6: ornamentbottom, horsetop, presenttop, toybottomSQAURE7: horsetop, toybottom, ornamentbottom, presentbottomSQAURE8: toytop, horsetop, horsebottom, ornamentbottomSQAURE9: horsetop, presenttop, toytop, ornamentbottomSo you can just cut out 9 small squares of equal size, and put those shapes on it, then try to match them together to make the big square. To make it easy,  I'd suggest just A1, A2, B1, B2, C1, C2, D1, D2. A-D representing the 4 shapes, 1-2 representing top or bottom.I know there's some work involved, but this is such a great one. :) You can also solve it in code.

Cute, but I don't think it's necessary to cut out squares and do it again. Title: Re: The Crazy Christmas Game Post by SWF on Jul 25th, 2003, 9:11pm Being that this problem has been sitting around unsolved for 6 months, I thought it would be pretty tough. I made the pieces and solved it on first attempt. Made a reasonable guess for the center piece, placed the pieces around it without a whole lot of thought, and everything matched up right away. Maybe it was just luck. Here is limited amount or reasoning I used:Hint: [hide]Noticed there was an excess of certain segments, and figured that some of these must therefore be on the edge of the big square. The small square with the most sides which match the excess segments was chosen for the center piece. I then placed pieces around the center piece trying to get the excess segments on the perimeter.[/hide]Full solution:[hide]The squares are numbered 1 through 9 as defined in the question. For each square I also give an orientation A, B, C, or D. 'A' has the first segment given in the original post at 12 O'clock, B has it a 3:00, C at 6:00 and D at 9:00.
