Revac-8 wins MindGames Arena social deduction AI track
Revac-8, an AI agent built for the Mafia-style Social Deduction track of the MindGames Arena competition, took first place by combining memory-based player profiling, social-graph analysis, and adaptive communication.
Score breakdown
Practitioners building agentic systems for adversarial or multi-agent environments can study Revac-8's memory-based profiling and social-graph analysis as concrete architectural patterns for reasoning under deception.
- 01Revac-8 is an AI agent designed for social deduction games like Mafia, where players must reason under uncertainty and deception.
- 02The agent won first place in the Social Deduction track of the MindGames Arena competition.
- 03Revac-8 evolved from a simple two-stage reasoning system into a multi-module architecture.
Mihir Shriniwas Arya, Avinash Anish, and Aditya Ranjan present Revac-8, an AI agent built to tackle the unique challenges of social deduction games like Mafia. Unlike deterministic board games where perfect information or exhaustive search can dominate, Mafia demands inference under uncertainty, interpretation of incomplete and intentionally misleading information, and strategic elimination decisions — capabilities that push well beyond conventional game-playing AI.
The agent's architecture grew from an initial two-stage reasoning system into a more sophisticated multi-module design.
Revac-8 was developed specifically for the Social Deduction track of the MindGames Arena competition, where it achieved first place. The agent's architecture grew from an initial two-stage reasoning system into a more sophisticated multi-module design. Its core components include memory-based player profiling, social-graph analysis that tracks patterns of accusations and defenses across game rounds, and dynamic tone selection that adapts the agent's communication style to the social context. The authors conclude that structured memory and adaptive communication are the critical factors driving strong performance in these high-stakes, deception-laden environments.
