Systems Index: Dungeons and Dragons and Dices

Status: Active Created: 2026-03-28 Last Updated: 2026-03-29 Source Concept: design/gdd/game-concept-v2.md

Overview

A solo-first dice roguelike where you roll dice, make Yahtzee-style hands, and deal damage. Collect passive relics that warp scoring rules and active consumables/innate abilities for dice manipulation. Branching map with combat, elite, rest, shop, and boss nodes. The Balatro-inspired chips×multiplier scoring creates emergent build synergies through relic stacking.

Co-op multiplayer is a future addition using the existing v1 networking layer.
