# Overrool > Roll for precedent. Object to hearsay. Win with the law. Overrool is an adversarial legal strategy courtroom card game. Players pick a side, spend strategy tokens, deploy precedent cards, cite statutes, and push the Judge's Favor Meter to 0 (dismissal) or 100 (victory). It embeds a global corpus of real, published landmark judgments from the United States, the United Kingdom, the European Union, Canada, Australia, South Africa, and India, with client-side factual citation verification and a single multi-role LLM turn. It is an educational simulation, not legal advice. ## Documentation - [README](https://github.com/z99wE/overruled#readme): overview, architecture, and quick start. - [AUTH](https://github.com/z99wE/overruled/blob/main/AUTH.md): Cloudflare accounts, deployment, hosted inference runbook. - [PRIVACY](https://github.com/z99wE/overruled/blob/main/PRIVACY.md): what the app stores and never stores. - [DISCLAIMER](https://github.com/z99wE/overruled/blob/main/DISCLAIMER.md): not legal advice. - [SECURITY](https://github.com/z99wE/overruled/blob/main/SECURITY.md): vulnerability reporting and posture. - [CONTRIBUTING](https://github.com/z99wE/overruled/blob/main/CONTRIBUTING.md): how to contribute. ## How it works - **Bring your own key.** Trials run a single structured LLM pass (Presiding Judge, Opposing Senior Advocate, Co-Counsel) directly from your browser to your own provider key — Gemini, OpenAI, Anthropic, or Groq. No keys, prompts, or case text reach an intermediary server. - **Factual grounding.** Citations are verified against an embedded corpus; unverifiable authority is flagged as exposure. - **Account sync.** Optional Cloudflare account syncs game progress across devices (and, for the workspace administrator, into server-side hosted inference on Workers AI). ## Licensing and status Open source.
