Erik Demaine and Martin Demaine's Puzzles:

CSAIL Annual Meeting 2018 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 2018 edition.

This puzzle is based on the series of “Fold-a-Cube” puzzles developed by Sjaak Griffioen and Oskar M. van Deventer in 2014.

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

The puzzle starts as a 3 × 3 square with two parallel slits (of length 2). You can fold the puzzle only along the grid lines. The goal is to fold the 3 × 3 puzzle down to a 1 × 1 × 1 cube that shows all six images (one per face of the cube):

  1. The CSAIL logo
  2. The MIT logo
  3. The MIT seal
  4. Tim the Beaver (MIT's mascot)
  5. The Stata Center (building 32)
  6. The MIT Dome (building 10)

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 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.
