Random Dungeon Generators

One of our favorite tools for TTRPG nights are random dungeon generators. A random dungeon generator is a tool, often used in role-playing games like Dungeons and Dragons, that creates a map of a dungeon or other type of underground environment randomly.

The generator uses algorithms (or dice, cards, random elements) to generate the layout, rooms, corridors, and traps of the dungeon. Players can use the generated map to navigate through the dungeon, discover hidden rooms and treasures, battle monsters, and uncover secrets. Random dungeon generators are often used to create unique and challenging game scenarios, as no two generated dungeons will be exactly the same.

Random Dungeon Generators come in a variety of forms from websites to books to dice and tile sets. All of these methods are fun ways to create dungeons on-the-fly. Many of the books listed can also help you fill your dungeon with treasures, traps, and foes along your adventure.

What is One Page Dungeon?

One Page Dungeon (OPD) is a format for creating and sharing role-playing game (RPG) adventures that can be played in a single session. As the name suggests, these adventures are designed to fit on a single sheet of paper, with all the necessary information and details condensed into a concise and easy-to-read format.

The concept of the One Page Dungeon was first introduced in 2009 by Alex Schroeder, a Swiss programmer and avid RPG player. Schroeder challenged himself to create a complete RPG adventure that could fit on a single sheet of paper, and then shared his creation online for others to use and build upon.

Since then, the One Page Dungeon format has become popular among RPG players and designers, with annual contests and compilations of the best entries. The format encourages creativity and resourcefulness, as designers must come up with clever ways to fit all the necessary information into a limited space.

One Page Dungeons can be played with a variety of RPG systems, from classic games like Dungeons & Dragons to newer indie RPGs. They typically include a brief introduction and background, a map of the dungeon or adventure site, descriptions of key locations and encounters, and any necessary rules or guidelines for the players.
