Abstract
Werewolf game, also known as Mafia game, is a social deduction game that
models the conflict between an informed minority (werewolf group) and an
uninformed majority (citizen group). This paper explores the optimal strategies
of the werewolf game from the perspective of game theory, focusing on cases
both with and without prophet. First we examine the existing strategy in game
without prophet and propose ``random strategy +", which provides an improved
winning probability for the werewolve group. Then we further study the game
with prophet, and find the game with prophet can be transformed into a
extensive game with complete but imperfect information under a specific rule.
We construct a model and design an algorithm to achieve PBE and maximize the
citizen group's winning probability. In the end, we examine a property of PBE
in game without any restriction.
