Core MechanicPbtA framework — roll 2d6 plus ability modifier, with 10+ as a strong hit, 7–9 as a hit with complication, and 6 or less as a miss. Mysteries have no pre-written solution; players gather clues through the Meddling Move, then use the Theorize move to propose a solution and roll to see if it is correct. The Theorize roll adds the number of clues found minus the mystery's complexity rating (6–8). Putting on a Crown after any roll lets a player bump the result up one tier at the cost of marking narrative consequences on their character sheet.Roll d100 equal to or under your skill percentage. Success tiers at half (Hard) and one-fifth (Extreme) of the skill value. Bonus and penalty dice adjust the tens digit. Failed rolls can be pushed for a second attempt at greater risk.

Best ForGroups who want a collaborative mystery game where players piece together clues and collectively theorize solutions, blending cozy small-town charm with creeping cosmic horrorInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.
HighlightsGold ENnie Award winner (Best Electronic Book 2023), no predetermined mystery solutions — players collaboratively theorize the answer from gathered clues, dual-tone structure balances cozy daytime vignettes with dangerous nighttime investigation, Crown mechanic lets players trade long-term character consequences for immediate fictional do-overs, spawned the Carved from Brindlewood third-party design frameworkSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.
ConsiderationsKeeper must improvise heavily since mysteries have no fixed solutions, Day/Night move split requires tracking time of day carefully, the dark conspiracy campaign arc may not appeal to groups who only want standalone mysteries, combat is not a focus and physical danger is resolved through the same general moves as everything elseChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaigns
