Erik Demaine and Martin Demaine's Puzzles:

CSAIL Annual Meeting 2006 Puzzle

In what has become a regular event, Erik Demaine and Martin Demaine give out puzzles each year at our lab's Annual Meeting in July. Here is the 2006 edition.

This puzzle is based on a 1941 "camel puzzle" by Strombeck Press.

[72dpi] [150dpi] [PDF] [PostScript]

Rules

Your goal is to fold the star-shaped puzzle into three triangles that make a complete beaver. (See image in lower-right corner.) You may only fold along the lines.

If you're stuck, you can read a hint.

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.
