This year we will run our fifth AIBIRDS Level Generation Competition. The competition will be held at the CoG 2020 conference in Osaka, Japan, August 24-27, 2020. In the following we give a brief description of the competition and the competition rules. You can find brief instructions on how to install and use the provided software as well as a link to more detailed instructions here. The results of our fourth AIBIRDS Level Generation Competition that was held as part of CIG 2019 in London, can be found here 

The goal of this competition is to build computer programs that can automatically create fun and challenging game levels. The difficulty of this competition compared to similar competitions is that the generated levels must be stable under gravity, robust in the sense that a single action should not destroy large parts of the generated structure, and most importantly, the levels should be fun to play and challenging, that is, difficult but solvable.

This competition will evaluate each level generator based on the overall fun or enjoyment factor of the levels it creates. Aside from the main prize for “most enjoyable levels”, two additional prizes for “most aesthetic levels” and “most challenging levels” will also be awarded. This evaluation will be done by an impartial panel of judges. restrictions will be placed on what objects can be used in the generated levels (in order to prevent pre-generation of levels). We will also generate 100 levels for each submitted generator and randomly select a fraction of those for the competition. There will be a penalty if levels are too similar. Each entrant will be evaluated for all prizes. More details on the competition rules and can be found in the detailed competition rules. You can also watch our instruction video. IEEE is sponsoring cash prizes of USD 500 for the winner of each of the three tracks. 

The competition will be based on the physics game implementation "Science Birds" by Lucas Ferreira using Unity3D. The winning generator from the 2018 competition by Matthew Stephenson is available for download and can be improved by entrants to create their own new generator. Questions regarding the respective parts should be emailed to This email address is being protected from spambots.
