Rules

Your goal is to fold the 3×3 puzzle into a one-square packet so that the top and bottom of the packet both show the same image of MIT, through a "frame" of MIT logos. (See image in the center of the back side.) There is only one solution. Only one identical pair of images will work. You can only fold along the black lines.

Printing Notes

This puzzle requires printing images on both sides with fairly close alignment. This can require some fiddling with your printer or photocopier.

The puzzle was designed for color printing, but it comes out fairly well on a black-and-white printer as well.

The PDF file is the best combination of printing quality and small file size. The PostScript file also has ideal printing quality, but the file is larger. In either case, you need a suitable viewer. Alternatively, you can print one of the images. If you can print images scaled to fit, use 150dpi. Otherwise, use 72dpi.
