# RELAY project > RELAY is an independent studio making story games that run inside AI tools such as Codex. Players learn by giving AI tasks, checking its work, and building things they can keep. Start with RELAY Day, a free solo game with three missions, or explore The First Signal, a longer story playable alone or with friends. RELAY Day takes about 30–45 minutes and introduces working with AI through creating a personal digital pet. No coding experience is required. The First Signal starts with Chapter I; the Full Edition includes three chapters, five roles, bonus challenges, and an Ability Atlas based on the player’s work. RELAY Day is an introduction, not a prerequisite for The First Signal. The game itself and access to the AI tools are separate. A free RELAY game does not include a ChatGPT/Codex subscription or unlimited AI usage. Check the relevant game page for setup, required features, account limits, and any additional API costs. The website has English, Russian, German, and Spanish pages, but language coverage differs by product. A translated landing page does not establish that the game is released in that language. Non-Russian purchase buttons currently open a release-notification form rather than checkout. Current availability, contents, requirements, and prices are on the product pages; displayed prices alone do not imply that purchases are open. English prices are in USD, German and Spanish prices in EUR, and Russian prices in RUB. The links below use the canonical public domain. Chapter I and the Full Edition share a pathname: keep `?offer=chapter-1` when linking to Chapter I. Articles are written for their respective languages and are not necessarily translations of one another. RELAY is independent of OpenAI; mentions of ChatGPT or Codex describe the tools used to play. ## Start here - [Studio — English](https://relay-project.com/): Overview, game editions, upcoming stories, and FAQ. - [Студия — Русский](https://relay-project.com/ru): Russian overview and game selection. - [Studio — Deutsch](https://relay-project.com/de): German overview and game selection. - [Estudio — Español](https://relay-project.com/es): Spanish overview and game selection. ## RELAY Day: free introduction - [RELAY Day — English](https://relay-project.com/games/relay-day): Three missions, pet creation, setup requirements, and the starting file. - [RELAY Day — Русский](https://relay-project.com/ru/games/relay-day): Russian game overview and instructions for starting. - [RELAY Day — Deutsch](https://relay-project.com/de/games/relay-day): German landing page; check current game-language availability before starting. - [RELAY Day — Español](https://relay-project.com/es/games/relay-day): Spanish landing page; check current game-language availability before starting. ## The First Signal: Chapter I and Full Edition - [Chapter I — English](https://relay-project.com/games/first-signal?offer=chapter-1): First chapter, beginner tasks, two main roles, requirements, and release notification. - [Глава I — Русский](https://relay-project.com/ru/games/first-signal?offer=chapter-1): Russian first-chapter landing page, contents, and current purchase options. - [Full Edition — English](https://relay-project.com/games/first-signal): Complete story, all five roles, solo and team play, Ability Atlas, and edition comparison. - [Полное издание — Русский](https://relay-project.com/ru/games/first-signal): Russian Full Edition contents, requirements, and current purchase options. ## Handbook and PDF quick reference - [Handbook — English](https://relay-project.com/handbook/en/): Practical reference for working with AI, prompts, tools, models, and troubleshooting. - [Handbook — Русский](https://relay-project.com/handbook/): Russian practical reference. - [Handbook — Deutsch](https://relay-project.com/handbook/de/): German practical reference. - [Handbook — Español](https://relay-project.com/handbook/es/): Spanish practical reference. - [PDF cheatsheet — English](https://relay-project.com/handbook/RELAY-Day-cheatsheet-en.pdf): Downloadable quick reference. - [PDF-шпаргалка — Русский](https://relay-project.com/handbook/RELAY-day-cheatsheet.pdf): Russian downloadable quick reference. - [PDF-Spickzettel — Deutsch](https://relay-project.com/handbook/RELAY-Day-cheatsheet-de.pdf): German downloadable quick reference. - [Guía rápida en PDF — Español](https://relay-project.com/handbook/RELAY-Day-cheatsheet-es.pdf): Spanish downloadable quick reference. ## Architect’s Notes: articles and tutorials - [Architect’s Notes — English](https://relay-project.com/notes): English articles about AI practice, Codex, agents, MCP, and making games. - [Записки Архитектора — Русский](https://relay-project.com/ru/notes): Russian articles and project stories. - [Notizen des Architekten — Deutsch](https://relay-project.com/de/notes): German articles and practical guides. - [Notas del Arquitecto — Español](https://relay-project.com/es/notes): Spanish articles and practical guides. - [Learn AI by playing](https://relay-project.com/notes/learn-ai-by-playing): How a story game connects AI tasks with results the player can inspect. - [Codex for beginners: the first task](https://relay-project.com/notes/codex-for-beginners-first-task): A practical starting point for a first Codex project. - [Игра с нейросетью](https://relay-project.com/ru/notes/igra-s-neyrosetyu): The cycle of a task, AI-assisted work, a checked result, and the next story choice. ## Optional - [Privacy Policy — English](https://relay-project.com/privacy/en): Personal data and subscriptions. - [User agreement — English](https://relay-project.com/terms/en): Terms for using the site and products. - [Политика конфиденциальности — Русский](https://relay-project.com/privacy): Russian privacy policy. - [Пользовательское соглашение — Русский](https://relay-project.com/terms): Russian terms. - [Sitemap](https://relay-project.com/sitemap.xml): Full list of indexable pages; use the curated sections above to choose a starting point.
