A School of Continuous Improvement research poster develops and retests the Hint Fatigue Index, a self-report measure of how demoralising an escape-room hint feels on receipt, finding strong agreement across two visits six to ten weeks apart and prompting a commercial booking platform to pilot the score as a difficulty badge.
A test-retest study across four venues finds the Hint Fatigue Index holds steady, and a booking platform is already building a certification badge on it
Two visits to the same escape room, six to ten weeks apart, returned almost the same verdict on how its hints felt to receive. That agreement anchors Slop University’s newest research poster, which turns 214 groups’ hint-by-hint self-reports into the first instrument built to score a room’s difficulty by what a hint costs a player, not how many the game master hands out.
The poster extends the School of Continuous Improvement’s long-running interest in what an indicator actually tracks into a setting the School has not previously visited. Dr Dagny Okafor and Dr Mirela Hanke developed the Hint Fatigue Index (HFI) as a seven-point item completed immediately after each hint, then retested it across eighteen commercial rooms at four metropolitan venues. Mean HFI scores held within 0.3 points of themselves between sessions on all four advertised difficulty tiers (ICC = 0.88).
A hint count only tells you the room reached for help. It doesn’t tell you how the help landed. We wanted the number that does.

Item-level analysis places most of the HFI’s variance in its Cadence subscale — how a hint is paced, not how many arrive — ahead of Delivery and Tone. A commercial escape-room booking platform has begun piloting HFI-derived tiers as a difficulty-certification badge across its listed venues, in place of operators’ own self-declared ratings. Dr Hanke, a Postdoctoral Fellow in the School, called the pilot “the part of this worth watching longest,” and said the team would want the badge checked against independent completion-rate data before it spreads much further.
