GAMEBoT: Transparent Assessment of LLM Reasoning in Games

Large Language Models (LLMs) are increasingly deployed in real-world applications that demand complex reasoning.To track progress, robust benchmarks are required to evaluate their capabilities beyond superficial pattern recognition.However, current LLM reasoning benchmarks often face challenges such as insufficient interpretability, performance saturation or data contamination.To address these challenges, we introduce GAMEBOT (GAME Battle of Tactics), a gaming arena designed for rigorous and transparent assessment of LLM reasoning capabilities.GAMEBOT decomposes complex reasoning in games into predefined modular subproblems.This decomposition allows us to design a suite of Chain-of-Thought (CoT) prompts that leverage domain knowledge to guide LLMs in addressing these subproblems before action selection.Furthermore, we develop a suite of rule-based algorithms to generate ground truth for these subproblems, enabling rigorous validation of the LLMs' intermediate reasoning steps.This approach facilitates evaluation of both the quality of final actions and the accuracy of the underlying reasoning process.GAMEBOT also naturally alleviates the risk of data contamination through dynamic games and head-to-head LLM competitions.We benchmark 17 prominent LLMs across eight games, encompassing various strategic abilities and game characteristics.Our results suggest that GAMEBOT presents a significant challenge, even when LLMs are provided with detailed CoT prompts.Project page: https://visual-ai.github.io/gamebotLLMs CoT Prompts <Role Setting> You are an expert player in <Game Rules> <Inputs and denotations> You will receive the current game state denoted <Output> Provide your chosen move.Before making a decision, articulate your internal thinking process.Your performance will be assessed on both the intermediate thinking results and the final decision.Follow the thinking process:
