This paper introduces Werewolf Arena, a novel framework for evaluating large language models (LLMs) through the lens of the classic social deduction game, Werewolf. In Werewolf Arena, LLMs compete against each other, navigating the game's complex dynamics of deception, deduction, and persuasion. The framework introduces a dynamic turn-taking system based on bidding, mirroring real-world discussions where individuals strategically choose when to speak. We demonstrate the framework's utility through an arena-style tournament featuring Gemini and GPT models. Our results reveal distinct strengths and weaknesses in the models' strategic reasoning and communication. These findings highlight Werewolf Arena's potential as a challenging and scalable LLM benchmark.

  6. Auditing Belief-Conditioned LLM Agents in Hidden-Information Social Deduction Games

    cs.MA 2026-07 conditional novelty 6.0

    An external belief audit framework for LLM Werewolf agents associates active belief with higher good-side win rates while exposing low action-belief consistency and rejecting forced consumption.

    cs.CL 2026-07 conditional novelty 6.0

    A released open-source testbed that privately probes LLM agents' beliefs during Mafia games shows agents are overconfident, over-predict suspicion by 1.5x, and rarely change outcomes when wrong beliefs lock in a vote.
