The hackathon begins on November 20th, Friday at late afternoon. Everyone gathers, we watch a short video keynote and the secret theme of the jam is announced.

After the announcement, people have time to meet each other and organize in teams. Teams are then challenged to make games based on the theme.

Games are to be completed by November 22nd, Sunday afternoon, after which every team will present their game on the stage. At the end, jammers vote for what they think is the best game and awards are given out.

Teams are formed at the first day of the hackathon. After the theme of is announced, participants will have a couple of hours to meet, share ideas and organize into teams.

Teams can have anywhere between 2 and 6 people. While there is no hard rule forbidding teams to have more than 6 people, we generally discourage it. Past editions have proved that the optimal size for a team is 4 to 5 people.

Can I jam solo?

You can if you want to, but the hackathon is very much about collaborating with others to stir creativity and make something special together.

What if I don't know anyone there?

Worry not. Our community is incredibly welcoming and friendly. We facilitate an environment that is accessible to everyone - from veterans to newcomers.
