Core MechanicPlayers roll a pool of 1–3 d6s against a target difficulty (4 for easy, 5 for average, 6 for hard). Every challenge starts with 1 die — add a second if the challenge matches the character's stat (Agile, Brawny, or Crafty), and a third if their role applies (The Veteran, Rookie, Medic, Gizmo, Detective, or Weirdo). Success means at least one die meets or beats the difficulty. Players spend luck tokens to invoke a perk and lower the difficulty by 1, and recover luck by letting their quirk cause a problem (raising the difficulty by 1). Grit tokens absorb failure consequences; a character who runs out of grit is removed from the scene. The referee never rolls dice during a challenge — they choose the stat and difficulty, then narrate the outcome. Extended challenges (chases, fights, infiltration) deplete a shared pool of effort tokens, one per success.Roll d20 + modifier vs. target number 10. Boons and banes (d6s) add or subtract from the roll, canceling each other out.

Best ForGroups who want a quick, comedic cosmic-horror RPG that pairs Baywatch-style melodrama with the Cthulhu Mythos. Tuned for pickup play and 2-4 hour sessions, with three tonal modes (Casual, Standard, Horror) that retune lethality without changing the core rules.Groups who want fast, dark fantasy with streamlined d20 mechanics and a sense of impending doom.
HighlightsThree difficulty targets and a 1–3 d6 dice pool make up the entire resolution system. Three tonal modes (Casual, Standard, Horror) adjust grit recovery rate, retuning the same rules from sitcom-style play to deadly survival horror without changing any mechanics. All heroes share a universal Slow Motion quirk — narrating a slow-motion moment recovers a luck token but raises the current challenge's difficulty. Adventure generator combines random Objective, Location, and Complication tables for pickup scenarios; also includes an Elder Gods & Cults table, a Monster Maker, and a mapped Sunset Hills setting.Fast character creation, quick sessions, single boon/bane mechanic replaces most modifiers, 11 levels keep campaigns short
ConsiderationsMechanically minimal — no advancement track beyond optional luck and grit cap increases, no gear lists, no tactical combat structure. Pacing assumes 2–4 hour sessions rather than multi-arc campaigns. Setting is anchored to Sunset Hills, California; running the game elsewhere requires reskinning the included cult, NPC, and location tables. Three difficulty values and a maximum 3-die pool give coarse resolution — granular skill differentiation is not the design.Dark horror tone limits genre range, setting tightly coupled to core rules
