Erik Demaine and Martin Demaine's Puzzles:

CSAIL Annual Meeting 2012 Puzzle

In what has become a regular event, Erik Demaine and Martin Demaine give out puzzles each year at our lab's Annual Meeting. Here is the 2012 edition.

This puzzle is inspired by another folding puzzle designed by Tsugumitsu Noji of Puzzlein, Japan.

Rules

You can fold the puzzle anywhere, but you may not cut it. The primary goal is to fold the 5 × 5 puzzle down to a 3 × 3 square that shows the CSAIL/MIT logo on one side. For additional challenge, you can add the secondary goal of keeping the back side completely white.

Printing Notes

The puzzle was designed for color printing, but it will work fine on a black-and-white printer.

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.
