The dungeon map generator digs a complete mini-dungeon in one click: five to seven chambers connected by corridors, drawn in the classic parchment-on-dark style of old module maps, under a name like The Sunken Vaults of Maldra. Each map arrives with an entrance marker, a stair, a treasure cross, usually a skull where something waits, and a one-line hook — which is everything a GM needs to run a site tonight and nothing they'd have to erase.
How the dungeon is dug
Rooms are placed on a twelve-by-twelve grid, sized two to four squares a side, and spaced so no two ever touch. The generator then chains them along the route a delver would walk, connecting each chamber to the next with an L-shaped corridor. The dressing follows the route's logic: the triangle marks the way in, the skull sits early where a guardian would, the stairs turn up mid-route hinting at a level you haven't rolled yet, and the red X waits in the last chamber, because treasure at the entrance is a trap and everyone knows it. Grid squares are drawn inside every room, so distances read at a glance for any system that counts them.
A map is a prompt, not a finished adventure
Five to seven rooms is deliberately small — it's the one-page-dungeon size, the side-quest size, the "you have forty minutes of session left" size. Keying it takes minutes because the map already asks the right questions: what's in the guarded second room, what did the mapping expedition miss, where do the stairs go? The name and hook do the same work from the other direction. The Weeping Cisterns of Urgath, where the lower level floods at every new moon, is half an adventure before you've written a word. Roll three maps and pick the one whose shape suggests a story; discard-and-reroll is a legitimate design method when rolls are instant.
At the table and on the VTT
The map is player-safe by design — marks hint at what's ahead without spoiling specifics, so you can drop the image straight into a VTT or a handout as the "old survey map" the party bought from a retired delver. Whether it's accurate is your call; the caption's warning that every survey disagrees about the room count is a license to improvise. For theater-of-the-mind tables, the GM keeps the image and narrates from it. For grid play, the PNG scales cleanly — each map square is a crisp 16 units in the source art.
Free SVG and PNG downloads
Both formats are free for your games, streams, and campaign notes. The PNG is a high-resolution render ready for Roll20, Foundry, Discord, or print — parchment tones hold up well on a black-and-white printer. The SVG is the original vector file, editable in any vector tool if you want to add room numbers, secret doors, or your own key.
Name the rooms, stock the halls
A dungeon needs contents, and the text generators next door provide them. The dungeon name generator writes a deeper history when the site graduates to campaign centerpiece; the ruins name generator and cave name generator cover what the place was before it went wrong; and the temple name generator answers the question the stairs keep asking — what, exactly, was worth building this far down?
