Free and Open-Source

Bringing math puzzles to the masses

We believe that we can do more as a community by working together. That’s why Mathematical Puzzle Programs does not charge for host campuses to run its events, and that’s why MaPP has a free and open-source culture with respect to its published works.

The contents of this site are licensed under Creative Commons Attribution 4.0 International, and we release our puzzle materials under similar licenses. This means that you have the right to use, remix, and share our mathematical content however you want, as long as you give appropriate credit to us.

We want to thank our volunteers across the country who have agreed to create mathematical puzzle content for us to license under these terms. Through your work, we hope to encourage more young adults to embrace mathematical thinking in their academics and careers!
