Global Game Jam 2013


With 319 jam sites in 36 countries (twelve new) and 16.705 registered participants, the Global Game Jam 2013 again broke all previous records. Over the weekend 3248 games were developed around the world. Also the fourth local jam at the University of Bremen was a great success: over sixty participants – students, hobby developers and professionals – designed and implemented 13 computer and two board games. The local event was organized by a group of computer science and digital media students around Anna Barenbrock, Daniel Böhrs, Dmitry Alexandrovsky, Georg Modzelewski, Philipp Dittmann and Toke Lichtenberg supported by Jan Smeddinck and Dirk Wenig from the TZI.

After a warm welcome by Rainer Malaka, the Professor of Digital Media at the University of Bremen, all the participants jointly watched two keynotes by Erin Robinson and Bret Victor and a message from Sid Meier, the famous creator of the Civilization game series. Afterwards, this year’s theme was announced: the sound of a heartbeat. During the following two hours the participants formed first teams and initial game ideas were developed. After a poster presentation of the concepts to all the other participants, the real action started. Partially without any breaks the teams designed, hacked, and tested for exactly 48 hours until on Sunday afternoon all games were presented to the audience. The results can be downloaded from the global website.

We thank our sponsors contruktiv, trafficmaxx, F1ELD and HandyGames for making this event possible!

The Global Game Jam

The Global Game Jam (GGJ) is an event which takes place all over the world at the same time. Here will gamers become developers and create computer or board games within 48 hours.

Together with your team you will build up a concept, create levels and construct the game logic. In the end of this programming-marathon all groups present their games and the best ones will be elected by all participants. But the fun of deliberation, creation and gaming together with your team should still be the focus of the event. Teams can be built beforehand or can be formed at the event plaxe itself. You do not have to be a professional game developer, but it is important that you bring a bit of creativity and, of course, lots of enthusiasm. In the beginning you will get to know the secret topic of this Global Game Jam, which has to be part of your game. This gives you the opportunity to quickly transform your idea in a creative way. Additionally there will be an information about the rules for getting extra points for the game rating in the end.

The GGJ is an exciting, challenging and fun event, which offers enthusiasts as well as professional game developers the opportunity to come together in a very special setting.

Participation is free!
