A blank grid has no key yet. Paint some rooms and place props, and the read-aloud writer will describe what you drew.

Read-aloud writer

Turns this layout into boxed text to read at the table, plus three tactical hooks. Uses AI; the map itself never needs it.

Quick answer: Press New five-room dungeon to roll exactly five connected rooms on 5-ft squares. The map key tells you which room is the entrance, the puzzle, the trick or setback, the climax and the reward, and each room is dressed to match.

The five rooms and what they are for

The structure comes from Johnn Four’s Five Room Dungeons, a widely used prep method. Room 1 is the entrance and its guardian: a reason the place has not been looted already. Room 2 is a puzzle or roleplaying challenge that cannot be solved with swords. Room 3 is a trick or setback that drains resources or raises the tension. Room 4 is the climax, the big fight. Room 5 is the reward, revelation or twist. The generator splits the map into exactly five areas, connects them in order and dresses each for its role.

Three ways to use this map

  1. A sealed vault opens for the first time in a century, and room 3 is the reason it was sealed.
  2. The puzzle in room 2 is a ghost who wants to be heard, not a lock.
  3. The reward in room 5 is a letter proving the patron lied.

Who lives here? Build one easy encounter for room 1, nothing or a social encounter for room 2, a hazard for room 3 and a hard or deadly fight for room 4, then check them in the encounter builder. Check the difficulty for your party in the encounter builder, then use the read-aloud writer under the map for boxed text.

Questions game masters ask

What is a five-room dungeon?

A short adventure structure built from five beats: an entrance with a guardian, a puzzle or roleplaying challenge, a trick or setback, a climax and a reward or twist. It fits one session, and the rooms do not have to be literal rooms.

Do the rooms have to be in that order?

No. The order is a default that builds tension. Many GMs put the setback after the climax, for example, a collapse as the party escapes with the treasure.

Can I use the five-room map in any system?

Yes. The map is 5-ft squares, which suits D&D 5e and Pathfinder, and the five-room structure is system-neutral.
