Erik Demaine and Martin Demaine's Puzzles

We love puzzles. When Erik was six years old, we designed and made puzzles as the Erik and Dad Puzzle Company. Now we do research on combinatorial games and puzzles, in particular analyzing the computational complexity of games and puzzles we like to play.

Below are folding puzzles that we designed for fun. Each puzzle also represents a mathematical unsolved problem that we have worked on, to illustrate what makes the problem so challenging.

You are free to print the puzzles out, play with them, and give them away as individual puzzles, but any redistribution must name the puzzle designers (Erik Demaine and Martin Demaine). Also, you need permission before publishing these puzzles in any form.

MIT CSAIL Annual Meeting Puzzles

In what has become a regular event, we give out puzzles each year at our lab's Annual Meeting. Over the years, the lab's name has changed, and the meeting changed briefly to semi-annual.
