Ravensgate Deep

How to start

1. 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.
2. The game loads. The fire door shuts behind you at the head of the stair, the whole complex below, the lamp reading 20.
3. Get the power up, then spend it. Restore the station's standby power, then choose how to spend it: the battery can carry the lights or the hoist, never both at once. Decide how long you can afford the lights.
4. Take a save. Say "save" at any point for a code that holds your place, your lamp, your breakers and your pockets. To resume, open the game again in a new chat and paste the code once it loads, or use aigamecards.com/resume.

Questions

Why can't I have the lights on and the hoist running?

The standby battery carries eight amperes. The lights draw five; the hoist draws five and needs the shaft fan, which draws three, so the way out takes all eight on its own. With the lights on, walking between lit places costs nothing; in the dark, every move costs lamp. Choosing when to switch is the puzzle.

Can I get stuck?

Yes. At least one route runs one way only, and the game tells you what it will cost before you take it, and again whenever you ask. A move your lamp cannot pay for in full is the last move you make, so check the lamp before you commit.

How is this different from asking ChatGPT to run a text adventure about an abandoned station?

Freehand, the station is generated as you speak. The corridor is north until you go north twice, the bar you left behind is back in your hands, and the shaft opens once you sound frustrated. Ravensgate Deep carries its map: eleven places, their exits, what lies in each of them and the answer to every lock are written into the card before you arrive. The flooded tunnel is still flooded on your second pass, a dead lift stays dead until you power it, and you can be stuck.

Is anything sealed or verified, like the mystery cards?

No. Ravensgate Deep is hand-built and checked: no hash, no dice, nothing to verify at the end. The map and the answers are written on the card and the AI reads them, which keeps the station fixed. In a sealed mystery the hash does a different job: it proves the AI did not move the culprit after you started guessing.

How long is it, and can I stop partway?

Forty-five to seventy minutes solo. Say "save" at any point for a code carrying your place, your lamp, which breakers are closed, what is in your pockets and what you have already opened. Paste it into a fresh chat with the card and you are standing in the same room with the same lamp reading. There is also an emergency telephone in the signal cabin, and "I give up" works anywhere at all — both call the crew down, both end the run at ten points, and both are far below any climb.
