An Alternate Reality Game (ARG) is a form of experience or expression that uses the overlap between reality and fiction, game and society, and institutions and play. ARG is not presented as a single completed genre or technique, but as a framework for exploring how game-like structures can intrude into everyday life. The key effect is not that participants clearly recognize “this is a game,” but that they briefly hesitate, wondering whether what they are encountering is real or a constructed device.

ARG is described as a niche culture historically sustained by a small number of creators and participants. It requires long-term design, substantial labor, and tolerance for contingency. For that reason, a fully playable, large-scale ARG is not treated as the goal. Instead, ARG is used as a conceptual lens for examining how far reality can be gamified and how far games can connect back to reality, with that unstable boundary experienced indirectly through multiple works or exhibition formats.

Ethical and practical constraints also apply. If ARG-like structures are introduced into an exhibition, each work should still function independently, and artists should not be unintentionally drawn into gameplay. For online character operation or continuous updates, AI or bot-like systems may be considered to reduce human workload.
