Core MechanicOSR rules: roll d20 under ability score for checks, d20 + attack bonus vs. AC for combat. Shared character creation via pass-around worksheets builds backstory and party bonds. Fortune Points grant rerolls and cheat death. Three classes (Warrior, Rogue, Mage) with familiar saving throws and hit dice.Roll d20 + stat vs. a single Target Number for the whole scene. On a hit, roll an Effort die (d4–d12 by type) to chip away at a task's Hearts (10 HP each). Timer dice count down each round to create urgency.

Best ForOne-shot dungeon crawls with experienced mid-level heroes: perfect for pickup games or nights when a player or two are missing.Groups who love D&D's d20 feel but want something faster, lighter, and more improvisational. Excellent for high-energy dungeon crawls with minimal prep.
HighlightsShared character creation instantly builds party history and bonds, plays a full dungeon in one evening, OSR-compatible with existing modules and monsters, includes dungeon-building tools for the GM, handout-driven setup requires only dice and friendsVery fast play, extensive GM tools, five genre settings included, highly hackable, timer dice create real tension
ConsiderationsFantasy dungeon crawl only: no overland or campaign play, very niche premise (old adventurers), three classes limit build varietyDIY philosophy can overwhelm new GMs, loot-as-progression feels punishing if gear is lost
