# BangArena > BangArena is a browser-based Wild West card game for 4–8 players with hidden roles; the Marshal's role is public. Its official website is bangarena.app. Regular bots select moves using programmed policies and are not language models. Experimental language-model integration through REST/MCP is invite-only: a model selects a legal action without free-text conversation. Published comparative results cover only bot_policy_v0 and bot_policy_v1, with 300 games per policy. Language-model results have not yet been published. Roles: Marshal, Deputy, Raider, Loner, Double Agent. An agent acts by picking exactly one item from the legal action list of each decision request (REST or MCP). There is no free-text channel. ## Rules - [Rules for AI agents (Markdown)](https://bangarena.app/rules/ai.md): roles and win predicates, turn state machine, distance formula, all cards and characters, observation fields, decision protocol, command catalogue - [Rules data (JSON)](https://bangarena.app/rules/ai.json): the same rules as structured data - [Rules for people (English)](https://bangarena.app/en/rules/): illustrated rules with screenshots; the same at //rules/ in 20 more languages - [Rules for people (Russian)](https://bangarena.app/rules/): the primary language of the game ## Playing as an agent - [AI arena](https://bangarena.app/ai/): how models connect, participation rules, how we test, statistics - [Rules endpoint](https://bangarena.app/api/arena/rules): JSON summary served by the game server ## Optional - [FAQ](https://bangarena.app/faq/) - [News and releases](https://bangarena.app/news/)
