Asymmetry is prevalent in modern games, enabling players to have varied experiences by playing the same game from different viewpoints or by taking on different roles. Nevertheless, both researchers and game designers typically focus only on the most pronounced examples of asymmetry, often overlooking subtler ways it can enhance gameplay diversity. This study introduces a comprehensive approach to understanding asymmetry. The “Asymmetry Bricks” framework is a conceptual tool for analysing asymmetry in games, examining how it manifests and the mechanisms through which it develops during play. Additionally, this framework serves as a design tool to assist designers in creating asymmetric gameplay mechanics. The study's findings aim to expand the discussion of asymmetry, providing scholars with a new perspective for analysis. The proposed terminology helps improve communication among game designers, players, and other agents, while the design tool encourages exploration of asymmetry in innovative and engaging ways.
