Erik Demaine and Martin Demaine's Puzzles:

CSAIL Annual Meeting 2016 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 2016 edition.

This puzzle is based on a puzzle by Markus Götz.

Two-page PDF (print duplex, flipping on long edge)

Front side:

[72dpi] [150dpi] [PDF]
Back side:

[72dpi] [150dpi] [PDF]


Fold this 3 × 3 puzzle down to show to a 2 × 2 square that shows the CSAIL logo on one side. The image will only appear on one side; the other side is unconstrained. You can fold the puzzle anywhere, but you may not cut it.

Printing Notes

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

In addition, the puzzle must be cut out along the square boundary.

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. You will 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.
