Game rules

Draft submissions

  • For draft submission, you have to create a project in the JunctionApp in the K&H HACK3 event where you can easily save this draft project without any completed description
  • When creating a draft project, it is enough for us if you only give a name to your project and choose the challenge you will work on
  • At the draft submission deadlines we would only like to see how many projects will be submitted on the different challenges.

Final submission

To submit your project, please follow these steps:

  1. Create a maximum 2 minutes long video pitch and upload it to YouTube (The video can have you talking, a live app demo (if you have one), some cool animation, etc... whatever fits best)
  2. Make a GitHub repo and set it to be public.
  3. Link the YouTube video and the repo in your submission form
  4. Create a short presentation in advance in case you get into the finalists, since you will have to pitch your idea in front of the audience.

Please, make sure to follow these steps strictly otherwise we will not be able to evaluate your project.

As mentioned above we will have different types of winners by the end of the hackathon.

First of all, after the final submission deadline the dedicated jury members will have to evaluate the projects in the different challenges. The jury will have time for it from 11:00 am until 1:00 pm. As soon as they went through all the projects we will notify the teams (2 teams / challenge) at 1:30 PM that will get into the finalists.

The finalists will get the chance to pitch their ideas at the Closing Ceremony starting at 2 PM. The Grand Winner will be selected from the finalists and chosen by a dedicated jury board after the live pitches.

Challenge winners will be also announced after the pitches right before the Grand Winner. Challenge winners will be selected by the jury of the given challenge.
