FAQs
What does this dungeon generator create?
Dice Cove generates instantly in your browser with a clickable map, themed room stocking by party tier, secrets you can hide for player handouts, lock-and-reroll, local history, and shareable seed URLs — plus Markdown, Discord, JSON, and PNG exports (including a player map without secret doors).
Is the same seed always the same dungeon?
Yes. Seed plus your filters (size, theme, level band, density, corridors, doors) determine the layout and room key. Share the URL and anyone opens the identical delve.
Can I give players a map without spoilers?
Turn off “Show secret doors (DM)” for the on-screen map, or use Player map PNG under More export. Room secrets stay in the DM key either way when you copy Markdown.
Can I keep the map and reroll hooks?
Lock rooms (layout + key), name, or overview, then click Reroll unlocked. Locked fields stay; wanderers and hooks can regenerate independently.
Does generation run on a server?
No. Everything runs in your browser. Nothing is uploaded; history is stored only on this device.
How does this relate to the town and world generators?
World sketches continents, town zooms into a settlement, and this tool delves the dangerous places between — use them together for full campaign prep.
