Core MechanicRoll d20 + attack bonus against descending Armour Class to hit in combat. Saving throws are roll-over by category (Breath, Death, Stone, Wand, Spell). Initiative is d6 per side each round. The GM (Maze Controller) tracks time, light, encounters, and resources: torches burn out, rations deplete, and random encounters escalate with noise and delay.Roll d20 + modifiers against a target number derived from the defender's Armor Class (descending AC by default, ascending AC optional). Attribute modifiers are compressed to −1, 0, or +1. Each class has a single saving throw number that improves with level. Side-based initiative is rolled each round on d6.

Best ForOSR veterans who want a traditional dungeon-crawling experience with descending AC, strict resource management, and classic class-and-level gameplay: especially fans of Barrowmaze and megadungeon play.Groups wanting the simplest possible version of original D&D: four classes, compressed modifiers, and intentional rules gaps that invite house rules and Referee creativity.
HighlightsComprehensive old-school toolkit with 11 classes and 8 races, heavy emphasis on dungeon exploration procedures (marching order, light, time), critical hit/miss tables add combat drama, designed by a megadungeon expert, extensive spell lists and equipmentAttribute modifiers compressed to −1/0/+1 keeps math fast and reduces stat dependency. Complete game in 143 pages including monsters, treasure, spells, and wilderness/dungeon procedures. A free PDF and a low-cost print edition make it one of the most accessible OSR games. Intentional rules gaps and a blank House Rules page explicitly invite customization.
ConsiderationsDescending AC and THAC0-adjacent math will alienate modern players, very large rulebook for an OSR game, tightly bound to classic dungeon fantasy, limited innovation beyond curating and polishing older mechanicsFour classes (three without the optional Thief) limits character variety. No formal skill system: the Referee adjudicates all non-combat actions. Level tables cap at 10, requiring house rules for extended campaigns.
