What will you build in a weekend?

For hackers at MLH Prime, hacking is an art form. It’s about creativity, self-expression, and proving to the world that you could really build something amazing in a weekend.


April 1-2, 2017: Hundreds of the most creative and inspiring student hackers from around Europe converge at the MLH Prime: Europe Regional in London. Here they team up, learn about bleeding edge technology, and build amazing projects over the course of 24 hours.

Hackers can expect to have access to the latest and greatest technology, world-class mentors, and some of their most talented peers from around the world.

Judging Criteria

  • Technology
    How technically impressive was the hack? Was the technical problem the team tackled difficult? Did it use a particularly clever technique or did it use many different components? Did the technology involved make you go "Wow"?
  • Design
    Did the team put thought into the user experience? How well designed is the interface? For a website, this might be about how beautiful the CSS or graphics are. For a hardware project, it might be more about how good the human-computer interaction is.
  • Completion
    Does the hack work? Did the team achieve everything they wanted?
  • Learning
    Did the team stretch themselves? Did they try to learn something new? What kind of projects have they worked on before? If a team which always does VR projects decides to switch up and try doing a mobile app instead, that exploration should be rewarded.
