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 Low Water into Claude on any plan: download it, then turn on code execution under Settings → Capabilities and add it at Customize → Skills → + → Upload a skill.
Low Water is a solo lighthouse-horror one-shot: keep the light burning through one night on the rock. Solo, 45–75 min 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 relief boat sets you on the rock at dusk. The lamp is cold and the keepers' boots stand by the door.
- Keep the light. Ration the oil, wind the beam, and read the log. Two watches of oil in the lamp, five charges in the store below — seven in all, one to spare if you waste none.
- Save your watch. Ask for a save code when you stop. To resume, open the game again in a new chat and paste the code once it loads, or use aigamecards.com/resume.
Questions
- What kind of horror is this?
- Slow lighthouse horror. You relieve an offshore light and find the keepers gone. You spend the night keeping the lamp lit and the beam turning while something climbs the rock. There is no gore: the barometer falls, the keepers' boots stand by the door, and voices call up the stair.
- How is it different from the other horror card, Vigil: White Static?
- Different setting and different engine. Vigil is videotape horror paced by printed dice rolls. Low Water is a lighthouse siege you run with no dice; how you ration the oil, wind the beam, and refuse the voices is the whole game. The danger rises as the tide falls and whenever you slip, and it drops back when you hold the light and do not answer.
- Can I lose, and can I win?
- Both are reachable. Keep the light burning to first light and you live. Let the oil run out or the beam stop and it climbs; go down the stair to answer the voices and it takes you. There is no unavoidable death and no dead end. Careful rationing and refusing the offers is a winnable night.
- Can I stop if it gets to be too much?
- Yes. Say "stand down" at any point and the watch ends safely with no final scare. The AI honours any limit you set. Low Water runs in ChatGPT, Claude, or Gemini, and a save code lets you break off and finish the watch later.
