The game card is the entire game, about 13k characters: every scene and rule, and the answers the AI referees from. Paste it into an assistant that can't open links, without reading it first: it gives the game away. The Skill installs The Gilt Horologe into Claude on any plan: download it, then turn on code execution under Settings → Capabilities and add it at Customize → Skills → + → Upload a skill.
The Gilt Horologe is a one-night heist RPG for one or two players inside a living clockwork vault that winds shut behind you, run by your AI game master. 1–2 players, 1–2 hours a run, free to play inside ChatGPT, Claude, or Gemini. No signup and nothing to install: open it in your assistant, paste the play prompt into another, or paste the whole card where links don't open.
How to start
- Open it in your AI. Tap Open in ChatGPT or Open in Claude, and press send, or paste the play prompt into any assistant that can open links. No paid plan required.
- The game loads. The AI loads Ironquill, our small rules system for AI-run role-playing, and sets you on the counting-house floor at the last chime.
- Run the heist. Describe what your crew does. The AI narrates, rolls the dice (in code if your app can run it, otherwise off the printed dice tape), and voices the warden, the vault's old servant, and the vault itself, while the wind clock counts the night down.
- Save when you stop. Ask for a save code before you close the chat; mid-heist is fine. To resume, open the game again in a new chat and paste the code once it loads, or use aigamecards.com/resume.
Questions
- What do I need to play?
- A chat window and about ninety minutes. Open it in ChatGPT, Claude or Gemini, with no signup, download or paid plan, and the vault opens on the next line. Dice are rolled in code if your app can run it, otherwise off the printed dice tape on the card, and save codes are plain text, so nothing about the night lives outside the conversation.
- What kind of game is this?
- A one-shot heist for Ironquill, our original tabletop role-playing system, run by an AI game master. You have one night inside a living clockwork vault to reach its heart and get out before it winds shut. Expect one 60 to 120 minute story with a clock working against you the whole way.
- Can I play solo?
- Yes. The Gilt Horologe is built for one or two players. Solo, the AI runs the vault, the warden, and every other character while you play your thief; the one deadly crossing always has a safe, clever route so a lone player is never forced into a coin-flip death. With two, you share the crew and split the decisions.
- What happens if I run out of night?
- The wind clock, the night's countdown, decides that. It advances at the start of every scene whether you fumble or not, so playing slowly cannot stall it, and a fumbled roll can tick it again on top. When it fills, the vault locks: anyone still inside is shut in until the next night, and a crew that got out with nothing has failed the job.
