Revac-8 AI Agent Wins MindGames Arena Social Deduction Competition

Revac-8 secured first place in the Social Deduction track of the MindGames Arena competition. The AI agent was specifically developed to handle the complex challenges presented by social deduction games like Mafia. Unlike deterministic board games, success in these environments requires reasoning under uncertainty and interpreting intentionally misleading information. The agent evolved from a basic two-stage reasoning system into a sophisticated multi-module architecture. This final design integrates memory-based player profiling with social-graph analysis of accusations and defenses. It also employs dynamic tone selection for communication. The research, documented in arXiv:2604.19523v1, highlights the critical role of structured memory and adaptive communication strategies for achieving strategic success in such deceptive contexts. The work demonstrates that victory in social deduction depends on inference and adaptability rather than perfect information or brute-force computational methods.
