Frequently Asked Questions

Frequently Asked Questions about Dungeons TOME.

How does Dungeons TOME work?
Dungeons TOME is a web-based tool for generating random dungeons. The algorithm uses a modified version of the method in the Dungeon Master's Guide (DMG), but should be suitable for any RPG.

Why create another random dungeon generator?
I couldn't find a random dungeon generator based on the rules provided by Dungeons & Dragons (D&D) in the DMG. Under the (possibly naive) assumption that the dungeons produced by the DMG were especially well-suited to D&D games, this generator came into being.

What are the differences between Dungeons TOME and the method described in D&D?
The are two major differences:
Firstly, Dungeons TOME has no 'trapezoid' shaped room, which is one of the possible rooms that can be implemented in the DMG method. The reason this hasn't been implemented is that the DMG has no real guidance as to the shape of the trapezoid.
Secondly, where the DMG refers to circular or octagonal rooms, those rooms will have square corners. The reason for this is that trying to work out if a square can or cannot be entered is, game-wise, annoying.

Are there any plans to implement more accurate trapezoid/circular/octagonal rooms?
Originally I thought that this wouldn't be possible, but I have come up with a way of doing it. I'm now undecided. Probably I will relent and implement it :)

Is it free to generate dungeons?
Yep. There are no ads and no requirement to provide an email address.

Will this always be free?
The basic dungeon generator will always be free. In the future there may be optional premium features such as full-colour dungeon maps, which may ask for a small donation to be made.

What can I do with the dungeons created by Dungeons TOME?
Dungeon images are licensed under the Creative Commons Attribution-NonCommercial 4.0 International License. You can click the link for a very simple (non-legalese) summary of what you can and cannot do. However, the major restriction is that you cannot use the dungeons for anything commercial. You cannot sell the dungeons, put them in a book that you sell, or put them on a website with adverts, for instance. If you want to do one of these things, please get in touch and request permission.

Can I use/print/give away the dungeons for use in my game?
Yes, unless you charge for your game.

Can I link to you?
Sure. Please link to

Are there any other RPG tools that you recommend?
If you aren't aware of it already, you should check out Donjon, which contains a huge number of random generation tools for RPGs.

Do you have any plans to release the source code?
No. But if it looks like I might abandon it completely, I'll probably open-source it.

I have a question that you didn't answer!
