Escape Rooms
Sluice
A surge shuts you into the Ferrand pumping station, and the only way up runs through five of the dead engineer's machines; the exit code was hashed before the water came.

Works with ChatGPT · Claude · Gemini. Free, no signup.
Opens ChatGPT or Claude with the play prompt ready; press send if it hasn't started. Same link on your phone as on your desktop. Another app? Copy the play prompt into it, or, if it can't open links, copy the full game card below. What works where.
No web access, or want it as an installed app?
The game card is the entire game — every scene, rule and answer, about 13k characters. Paste it when your assistant can't browse the web. The Skill installs Sluice into Claude on any plan: download it, then turn on code execution under Settings → Capabilities and add it at Customize → Skills → + → Upload a skill.
Sluice is a free escape room you play inside ChatGPT, Claude, or Gemini. Five machines, one chain, and an exit code sealed before the outer gate dropped. Solo, 20–40m a run. No signup and no app — open it in your assistant, or paste the play prompt anywhere else.
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 card commits the escape code to a SHA-256 hash, then drops the outer gate behind you.
- Work the mechanisms. Trace the circuit, order the valves, read the gauges, set the gears; each answer keys the next while the glass falls.
- Escape and verify. Say the code at the crown hatch, then hash the published reveal to check the seal held.
Questions
- Can an AI run a logic puzzle escape room?
- Yes, because it isn't the one solving. Elias Ferrand set the plant down in the order it must be worked, and every mechanism — the fuse board, the valve order, the gauge bank, the gear train, the pipe schedule on the crown hatch — already has its one answer written on the card. The station will not show you a machine until the one before it is solved, and it has no answer to give but the one Ferrand wrote down.
- How is the ending kept fair?
- The tide can't be argued with and neither can the code. Its SHA-256 fingerprint was fixed before the card shipped; the station reads that fingerprint to you as the outer gate falls, and once the run is over you hash the reveal and watch the two line up.
- Do I need to be good at puzzles?
- You need to be willing to be methodical. Nothing here is a cipher — it's a circuit to trace, five valves to sequence, a logic grid, a gear train, and a pipe schedule — and each has a three-step hint ladder plus an answer on request, so a stuck player pays in freeboard and keeps moving.
- What happens if I run out of time?
- The gallery goes under with you in it. At zero freeboard the water tops the last of the air and the run ends trapped, scoring nothing — a flooded gallery never scores above an open hatch. Say "save" at any point and the same mechanism, at the same freeboard, is waiting in a new chat.
- How close does the water actually get?
- The glass starts at 300 cm and only falls: 10 cm for a wrong answer, 25 cm for a hint, 50 cm to have a whole mechanism handed to you. Thinking is free. Buying all five answers outright costs 250 cm and still leaves you air; it is grinding every hint ladder to the bottom that drowns people.
- Has this room changed since it was released?
- Once. On 28 September 2026 Sluice was re-sealed as a second edition (v2.0.0): the crown hatch now reads Ferrand's pipe schedule instead of an eight-line plate, so the last mechanism draws on work you did earlier in the station. Every other mechanism and the escape code are unchanged. The first edition's seal (v1.1.0) still verifies at /verify.
12+ — themes of captivity and drowning; the fail state is a flooded gallery, and the engineer whose log you follow died in the well.
