At 17:00 (local time) on Friday afternoon, the organisers will reveal the global theme to the jammers, and they will have to make a game around it. As an example, last year the theme was the sound of a beating heart, so the jammers made games about hearts, and around the concept of beat, rhythm, and pulsating elements.
A common theme is surely a challenge, but it is also a way to connect together all of the games created during GGJ, and having something to start from also fosters creativity!
Hardware and Software
Jammers will be able to use any software they'd like, provided they bring it themselves. They can also use any framework or piece of code they have created before the jam, but it is highly prohibited to come with a game that's already been made, or even started. The spirit of the GGJ is to tackle the challenge of making an entire game in only 48 hours!
Jammers are required to bring their own laptop and all the software and hardware they will need to create the game. We will only provide tables, and there will be power outlets and internet access for everyone. We will provide some power strips and LAN cables, but it's better if you also bring some for yourself.
All of the game created will be released under the Creative Commons Attribution-Noncommercial-Share Alike 3.0 Unported
, which means that the jammers will retain all of the rights on their games, but the organisers will be able to share them around. This is of course only valid for the version of the game specifically created for the jam, if the jammers feel like expanding their game after the jam and selling it, they will be totally free to do so.
As every year, we strongly encourage jammers to come to the event without
a team. They will have some time before the jam to socialize with the others, and find some team-mates.
This is not a requirement and you can come with a team that's already been formed before the jam, though we will hate you a little bit :)
As for the size of the team, there's no mandatory number either. Teams can go from one person, to as many as you like. We do strongly recommend not to go over 4, as big teams are really difficult to manage in the limited span of 48 hours.
Jammers should bring sleeping bags and blankets, to make sleeping more comfortable. There will be some space reserved for people who want to sleep without being disturbed, and several bathrooms always available.
There will be some moments when we ask jammers to be around, such as when revealing the theme, or during the final games presentations. Once the jam is on though, jammers will be able to manage their own time schedule. Anyone will be able to leave the venue at any time, to reach restaurants and bars around the site, or to go home.
