FeynGame-2.1 – Feynman diagrams made easy

FeynGame is an open-source software tool to draw Feynman diagrams, but also to get acquainted with their structure. This article reports on a number of new features which have been added to FeynGame since its first release. These include full support of LaTeX for the line and vertex labels, the possibility to automatically include momentum arrows, new graphical elements, and new pedagogical features. FeynGame is freely available as jar or MacOS app file from https://web.physik.rwth-aachen.de/user/harlander/software/feyngame, and as source code from https://gitlab.com/feyngame/FeynGame.
