Short version: This is for you if you want lots of unfurnished, unpopulated, one-page dungeon maps, and tables of random room contents.

The first section is "100 Original Maps," except it's 82 maps, not 100. Then you get "77 Other Maps" that were published previously, apparently. The 77 figure is accurate, so that's 159 maps in total, not 177.

All the maps are one-pagers with about one or two dozen rooms. None of them have overlapping layers.

The maps don't include grids or scale indicators. There's no indication of room height.

A few dungeons include pits, but the majority of changes in depth are marked as stairs -- no slopes, ladders, chutes, or other options. There lots of doors; none of them are marked as secret doors.

Every dungeon has an evocative name (such as "The Warehouse of Sprax"). There's no description, backstory, or hooks, so the name is just for inspiration.

Very few of the dungeons have multiple entrances, and fewer still have entrances in different parts of the map. From an in-world perspective, a single entrance is a dangerous single point of failure, whether you're a dungeon resident or a dungeon delver. Blocking the sole exit entombs or imprisons everyone inside. From a gaming perspectve, a single entrance diminishes player agency. It doesn't give the players any choice over how to enter or leave. If you like jaquaying a dungeon, you'll want to doctor the maps to add another outside entrance. A few of the random table results could give you alternate exits to the outside.

Most of the maps allow multiple paths that the players could take through the dungeon, so that's good for player agency. Some maps are fairly linear instead.

In every map, the rooms are unnamed, undescribed, and unfurnished. If what you really need is a layout, you're in luck. If you want a furnished dungeon, you're out of luck, unless the random tables fill that need for you.

There are no natural features or water sources on the maps. Everything is either a room or a hallway, and almost all of them are rectangular with vertical and horizontal sides (very few diagonals or curves). You can roll up a well or river randomly on the tables (only a 1% chance of each, each time you roll), so you'll probably want to doctor the maps yourself if you want water in there somewhere.

Seemingly all of the maps assume an underground environment. There are no windows on any map, for example, although you can roll one up randomly on the tables. In many cases, you could declare that portions of the map are above ground, and then you'd add windows, outside entrances, and so on as desired.

The "1d100 Dungeon Encounters" section offers 49 pages of random tables (1 initial table, 48 pages of subtables). You start with a table of 100 entries: 4 character types (dwarf, halfling, human, or elf), 7 mundane animals (rodent, wolf, etc.), 1 "monster" (a ghost), several room types (pantry, barracks, etc.), a couple of dozen fixed features (a tree, a bridge, etc.), and dozens of entries for loose items.

Regarding room types, you can easily come up with several that aren't represented in the tables, especially if your dungeon has a particular purpose or theme (a community, a monstrous lair, a stronghold, a holy site, a secret hideaway, catacombs, etc.). You'd have to come up with your own themed room types.

The initial d100 result leads you to subtables that add a few details. For example, if you roll up a vase, you can then roll for its size, position, and contents. If you roll up a human, you then roll for the human's size, disposition, and profession. Some subtables indicate that the result is magical or valuable, leaving most of the details up to you.

The product info says it's system-agnostic, but the tables make occasional references to d20 terms and concepts (damage dice, alignment, etc.). There's not much of it, so you could easily tweak it for a different system.

You'll often need your improv or creative skills to put the tables to good use. The table results might give you, for example, a note with a poem of death on it, a book that's sitting on a raised dais, or a wolf. But then what? Why is that wolf there? What makes that book interesting, valuable, useful, challenging, or dangerous to the players? What's the poem's connection to the dungeon or the adventure? The tables hand you a prop (or a being), but the rest is up to you.

What it all comes down to is that you get 159 empty dungeon maps and tables of random room contents.

Excellent resource, expecially for the price. The maps (177!) are one page spreads of varying complexity, with an old-school stylized black and white look. For me the random tables really make this product shine. The maps themselves are unfilled by detail, furnishings, etc, but the amount of inspiration in the large number of tables will easily help make the dungeons come alive. I particularly recommend this for new Game Masters or GMs with less time for prep, but it is also a very good buy for GMs who simply want A LOT of material to work with at a reasonable price.

This is probably one of the single best resources I own as a Game Master. This book gives almost everything a GM needs to create a complete adventure for a night of fun. You can pick any of the 177 maps and just roll randomly to fill the adventure with tons of unique and interesting encounters and events. The level of creativity the author went into is truly mind blowing to me. Whether I want to just throw together an adventure for the evening, or want to spice up a detailed campaign this book is extremely useful. The reasonable price is an added bonus as well.

This is fantastic to get some dungeons designs all set for you to put monsters in for your players to adventure in. Open ended so you can do what you want in them. Fantastic for a DM that needs to put something together quickly for an adventure.

great product would have paid twice as much. I use it every time i build or at least i take something from it everytime.

I have to disagree with the last reviewer. This product is worth its asking price. Each dungeon costs you a little over 3 cents and you have a large variety to chose from.

At it's current price point ($5.99), this just isn't worth the money spent. The first half of the document is a collection of featureless dungeons with no real rhyme or reason to them. You would really be better off making the dungeon as you go at the table.

The random tables are ok, I guess, but none of them are particularly exciting. The overall layout is sparse to say the least. The maps are poorly drawn dyson style maps with seemingly random fonts for the dungeon names. The tables are all grey scale basic tables you would see in a basic word processor. Other than that, everything is white and bland without any sort of layout design.

With the large amount of quality products on this site, this product just doesn't earn the price point it is listed at. If it got dropped to $1 or "pay what you want", I would have rated it at 2 stars instead.
