Dimensional Dungeons

About Dimensional Dungeons

Dimensional Dungeons adds limitless procedurally generated dungeons to Minecraft! These dungeons are all placed in a single, separate dimension which can be accessed from a portal anywhere on the Overworld. (Such as in your base!) This makes the dungeons themselves renewable and it provides challenging, replayable content.

The dungeon dimension limits building and block breaking. This allows for a proper adventure mode-like experience on a survival server. For example, I can use pistons in my traps without giving the player free pistons. Obstacle courses can't be bridged over. Combat can't be trivialized by building fences around mobs. And light and darkness matter when you can't place torches!

Besides challenges in room design the dungeons are also randomly populated with enemies and worthwhile loot! Many rooms with valuable treasure chests require solving a puzzle that will test your knowledge of Minecraft game mechanics. Currently all of the builds are 'vanilla' and no modded blocks or command blocks are used. The goal is to feel vanilla-lite and to be fair to the player.

For modpack designers and server admins there is also a powerful config file which allows for customization of the block protection in the dungeon dimension and many other features. Also the rooms themselves are configurable in the common config so admins can remove existing rooms or add custom rooms. 

In Game Information

To get started you'll need to build a portal, craft some blank keys, and "activate" your blank keys. This video describes everything.

Here is a German showcase from VegaCraft which shows a much newer version of this mod:

 Additional information can be found on the new Dimensional Dungeons Wiki! There is also a Patchouli guidebook if you (optionally) have that installed.

From The Developer

TEN MILLION official downloads! Recently Dimensional Dungeons has grown beyond what I ever thought possible. I'm glad so many players have decided to make Dimensional Dungeons a part of their worlds. 
Thank you, everyone.

This is my first Minecraft mod and I'm very proud of it, but not too proud to listen. Please report bugs, issues and suggestions anywhere you'd like - either here on Curse, on Github, or in the Dimensional Dungeons Discord. I read every ticket and comment. The Discord also has a lot of information about modding this mod and making it do interesting things in modpacks. If you would like spoilers for the puzzle rooms I'll share those too. Puzzle spoilers are now also on the Wiki!

Permission is automatically granted to use this mod in any modpack. I would appreciate a link back to this page, please. If there is a feature or config setting I can add to make your modpack more interesting just request it in the comments and I'll consider it. I care a lot about mod compatibility.

Recently, updates to this mod have been focused on porting to the latest version. Minecraft itself has undergone a lot of internal changes from 1.20.1, to 1.20.4, to 1.21.0, to 1.21.5, and now 26.1. Each of those versions have enabled new and fun datapacks, but broke Java mods a big way. And I support that. Because what helps datapacks, helps Java modding in the long run too.

Latest News

Last updated: May 6th, 2026

Finally 1.21.10 is here! I've only made two "blog posts" on this page in the last year: one for the release of 1.21.1, and one for the release of 1.21.4. And both posts made excuses for how long those ports took me as a developer. There have been a lot of invisible technical changes, but I think I'm finally through the worst of it. Version 26.1 could prove me wrong? But I may also choose to plant and start working on new features again!

At this point I don't think I can update 1.20.1 anymore. That version had a good run, and it recently crossed 1 million total downloads (across 9 jars) for Dimensional Dungeons. But the code is too different from the latest. And Minecraft itself is too different. (You'd be surprised how many seemingly normal builds break between versions.) Right now I'm currently considering an update for 1.21.0 (with 1.6 million downloads already), moving on to the absolute latest 26.2, or staying on 1.21.10. I'm not sure what the modding scene needs. Your feedback to me could make the difference! Please let me know in the comments or in Discord which of those 3 options you'd rather see me persue.

Also, shoutouts to the modpack FTB Stoneblock 4! I learned that Dimensional Dungeons was being included when they reached out to me for permission to redistribute my mod. I thought this pack was a lot of fun and I love what they did with DD. I've always said that I wanted DD to be highly configurable and customizable for modpacks. And I don't want to spoil it, but they did something very unique and very custom for DD.

UPDATE 5/24:

Porting to 26.1.2 is complete! This port was actually very easy, but only since I was already on 1.21.11. I'm definitely going to stay on this version and work on features and rooms. But first, a short backport of the new textures to 1.20.1 and 1.21.1 since I know many players are still on those versions. This is really the last jar for 1.20.1, I hope.

FAQ:

Q: Can you add a config option to add loot from other mods if they are installed?

https://github.com/AllenSeitz/DimDungeons/wiki/Datapacks-for-Dummies

https://github.com/AllenSeitz/DimDungeons/wiki/Basic-Dungeon-Loot-Tables

Even though there is an official way to do this without mods I'm still considering it because of how high the demand is.

Q: Help! I'm stuck on the puzzles.

A: Try the official spoiler wiki! Official Puzzle Solutions

Q: When I try to activate a key, I see particle effects and hear a sound, but the key remains unchanged.

Q: There are structures from other mods overlapping the dungeon. (Or, mobs from other mods are spawning and I don't want them to.)

A: Those mods shouldn't be blindly inserting themselves into every biome and dimension that is installed. But if they are then hopefully they have a blacklist and you can add either dimdungeons:dungeon_dimension (the dimension id) or dimdungeons:biome_dungeon (the unique biome) to their blacklists. The biome "category" of my dungeon biome is "none" which should be a clear sign to these mods to skip adding structures. Consider reporting the issue on their bug trackers if it is causing a problem for you. If you need to whitelist or blacklist the new building dimension that dimension id is dimdungeons:build_dimension.

Q: My players are being treated as if they are outside the worldborder (suffocation damage, red tint) when they enter a dungeon. How do I fix this?

A: Unfortunately because of a bug by Mojang the /worldborder command would set the worldborder size for every dimension all at once prior to Minecraft 1.19.2. In other words the worldborder appears the same size in every dimension. This cannot be easily changed or hacked around on my end. And although the algorithm for building the dungeons in the void has changed from 1.16 to 1.18 to 1.20, all versions will likely exceed your reasonable worldborder of 5000 or 10000 blocks very quickly.

This is regrettable because Dimensional Dungeons is the ideal mod for providing renewable exploration within a limited worldborder!

The only fix I can offer is to download another mod that fixes this bug. If you search Curseforge for Forge mods with "worldborder" in their title you should be able to find something that works for any version of Minecraft that I've also released for.

For Public Server Operators (updated May 8th, 2022 for the latest version of 1.18.2) - still relevant in 1.21

Dimensional Dungeons is designed to offer "renewable adventure" and should be a wonderful addition to your server. Your Overworld won't be covered in these structures, and players won't have to generate or explore hundreds of chunks to find them. If you have a small world border then maybe this mod can help you solve the problem of your players looting everything within the border and leaving nothing for future players?

All dungeons are placed in a single dimension with 8 chunks of void space between. This helps to keep players from loading multiple dungeons and it provides other benefits. The teleport coordinates of each dungeon are determined when the corresponding key is activated, but the dungeon isn't built until the key is placed in a keyhole. Since 1.18.2 building dungeons causes minimal lag.

It is safe but unnecessary to reset the Dungeon Dimension. Your old looted and forgotten dungeons will sit in unloaded chunks forever. And players will be able to create new dungeons forever. There is no need to "free up space". However if you do choose to reset the dimension then players will be unable to exploit old keys because each key can only build a single dungeon. Additionally, there is also a safety feature in place to detect when a dungeon has been deleted and then politely inform the player, rather than continue and teleport them into the void. So in short, by resetting the dimension, you're really just invalidating all of the used keys on your server. (But this may be what you want.)
