Last updated 21 July 2026. The honest limits of what this software can do for you.
Clue Stack helps you design, validate, test and manage puzzle sequences. It does not assess physical safety, structural integrity, fire compliance, emergency egress, electrical safety or occupancy limits. Nothing in the product should be read as certification of any kind. Your venue's compliance with local law and your own inspection routine remain entirely your responsibility.
Simulated results are probabilistic models built from behavioural profiles, not predictions about any specific group. Solve time spreads, stall heat maps and difficulty curves are decision aids for comparing versions of your own room. They are not a substitute for real playtests with real people, and we recommend never opening a room to the public on simulated data alone.
Validation confirms that your sequence is reachable, free of circular locks and free of orphaned puzzles. It cannot tell you whether a puzzle is fun, fair, culturally appropriate or solvable by someone who has not seen the answer. That judgement is yours.
Clue Stack models your props and control systems and does not currently actuate them. Wiring notes, firmware versions and reset checklists are records you maintain. Always verify against the physical installation before a shift.
We back up regularly and export freely, but you should keep your own copy of any room you would be devastated to lose. Export is one click and always free, including on the Sketch tier.
Clue Stack is in active development. Features described on this site may change and beta workspaces will occasionally show rough edges. We will tell you plainly when something is experimental rather than dressing it up.
