  • All hacks must be built by accepted, confirmed, and checked-in HackPrinceton attendees. (This includes registered and checked-in Princeton students.)
  • Teams must consist of no more than four members.
  • Hackers must be a current student, or have left school within the past year, and present enrollment identification (i.e. student ID) to a HackPrinceton organizer if asked.
  • Due to university liability requirements, individuals must be at least 18 years old.


Submissions are due on Devpost by 9:00 AM on Sunday, April 3rd. After you submit, you can edit your submission until the deadline, so you are encouraged to begin your submission early. We are not able to accomodate late submissions.

Judging Criteria

  • Originality
    How original is the idea? Is it simply a repackaging of a previous project or is it something that has never been done before? Projects can also blend two concepts together in a refreshing new way.
  • Technical Difficulty
    Does the project take on technical challenges? What parts of the project did your team invent, and how did you build upon existing tools and technologies?
  • Design
    Does it feel like a quickly hacked-together project, or something that is well thought out? Is the user experience and interface smooth and well-designed?
  • Enjoyment
    Is the project zany, interesting or just plain amusing? Will it bring a smile to the face of those who see it, whether they are adults, teenagers or little kids?
  • Usefulness
    Can this hack be used in real life to better somebody's life? Is it enough to justify people wanting to use it?
