Creepy horror games for ChatGPT, Claude & Gemini
Updated
Solo horror one-shots for 16 and over: one night shift, one night on a lighthouse rock, and nobody coming. 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.
An AI horror one-shot is a single-session scare the assistant narrates while the card holds it to the consequences. The card fixes what the threat does and when, so once you are in trouble the game follows through to an ending.

Why does AI horror go soft, and what stops it?
Assistants are agreeable, and agreeable is the enemy of horror. Left to improvise, the thing in the dark stays a rumour: the danger is described, then quietly withdrawn the moment it would cost you something, and you end up reading atmosphere with nothing at stake.
Both cards here have a fixed shape: one night shift in Vigil, one night on a lighthouse rock in Low Water, and nobody coming. The card sets out what the threat does, what your choices spend and what cannot be undone, so the escalation happens whether you engage with it or not. Vigil also draws its bad moments from a dice tape, a list of rolls printed on the card before you start, so they arrive on a fixed sequence. Low Water uses no dice: the danger rises as the tide falls and whenever you slip.
Both are built for one player alone, and neither relies on gore. The fear comes from a schedule that does not care how you are doing.
Questions about creepy horror games
Can I win, or does it always end badly?
You can win both, and neither comes down to luck. In Vigil you survive by refusing: keep your name to yourself, do not answer what is on the reels, and reach 6:00 a.m. with the Static, its dread meter, still under 8. In Low Water you keep the lamp lit and the beam turning until first light and do not go down to the voices. Play carelessly and answer everything, and either night takes you.
How intense are these, and can I set limits?
Both are rated 16+ for dread and isolation; there is no gore. Tell the assistant at the start what to keep off the table, and the card tells it to honour any limit you state. You can also stop at any moment: say "lights on" in Vigil or "stand down" in Low Water and the night ends at once, safely.
Do I need to finish in one sitting?
They are built as single sittings of 45 to 90 minutes, which is the length the dread is tuned for. If you have to stop, say save and the game prints a plain-text save code to paste into a new chat with the card later. Vigil's save also records its place on the dice tape, so the night resumes on the roll it would have reached.
