AI Game Cards

D&D-style RPG prompts for ChatGPT, Claude & Gemini

Updated

Tabletop role-playing adventures your AI runs as game master: three one-sitting stories and a campaign's first chapter. Free, no signup. Each game is a ready-to-play prompt (we call it a game card) that you open in your own AI assistant.

A tabletop RPG played with an AI is a role-playing game in which the assistant runs the world, the other characters and the rules while you play your own character. The card supplies a complete rules system and the dice, so outcomes come from fixed numbers the assistant has to follow.

How does an AI run a fair role-playing game?

With no rules in front of it, an assistant playing game master agrees to everything. Nothing tells it what a hard climb costs, so danger stays a matter of tone: you are told a fall would be deadly, and somehow you never fall. All four cards on this shelf run Ironquill, our own small rules system, which sets the numbers before you sit down: what each skill is worth, what happens as your Strain (harm, fear and fatigue, counted from 0 to 6) climbs, and what happens when a clock fills.

Dice are rolled in code if your app can run it, otherwise off a published dice tape: a list of d20 rolls generated from the card's id and version and printed on the card before you start. Every roll is shown, as d20=NN from code or tape#N=NN from the list. A tape roll can be checked against the list at /verify/, and your save records your place on it.

Every reply ends with a one-line status readout we call the ledger: scene, Strain, what you carry, any running clocks. The state sits on the page, where a long session cannot lose it as the chat scrolls away, and the same line is what your save code is built from when you stop.

Questions about D&D-style RPGs

Can ChatGPT or Claude really be a game master?

Yes. Voicing characters, describing a room and reacting to a plan nobody expected are things assistants do well. What they do badly is referee their own story: nothing stops them softening a consequence they have just described. A game card closes that gap with a written rules system, dice the narrator does not choose and a status line printed every turn, so the hard calls follow the card.

Do I need to know tabletop RPGs to play?

No. The game master explains each rule the first time it comes up and offers ready-made characters to choose from. Ironquill is small on purpose: a Calling, six skills, one Strain track (Bramblewood's gentler version calls it Fluster) and the odd clock, so a first session goes on the story. If you have played tabletop games before, the nearest comparison is a light narrative system, where skills matter and a single roll rarely ends a scene.

How long is a session, and can I stop in the middle?

From 30 minutes for Bramblewood to about 3 hours for The Severed Spire. Say save at any point and the game master prints a plain-text save code holding your characters, their gear, any clocks and your place on the dice tape. Start a new chat with the card, in the same assistant or a different one, paste the code, and you pick up at the same scene. The Severed Spire is Chapter 1 of a planned three; Chapters 2 and 3 are not out yet, and the save you take at the end of Chapter 1 is what will carry your company into them.

Can I play with friends?

Yes, at one screen. Bramblewood takes up to four players, who share its three woodland friends and take turns deciding; The Toll at Blackbridge, The Severed Spire and The Gilt Horologe take two, one character each. One person types for the table, and a save keeps every character, so a group can stop and resume together. Every card can also be played and finished solo.
