The Game Master’s Book of Traps, Puzzles, and Dungeons – A Review with Bonus Content

Every great dungeon is more than just a collection of monsters and loot—it’s filled with deadly traps, devious puzzles, and chambers designed to test the wits and resilience of any adventuring party. The Game Master’s Book of Traps, Puzzles, and Dungeons is a fantastic resource that delivers all of these elements in one well-organized package. Whether you need a fully designed one-shot, a last-minute puzzle to stump your players, or a way to make your dungeons more than just combat arenas, this book has you covered. You can check out my last review here.

A Full Session of Play in Every One-Shot

The book includes three one-shot adventures, each designed to provide a complete session of play. These adventures are self-contained, meaning they can be run as standalone experiences or slotted into an ongoing campaign with minimal effort. The encounters are balanced, creative, and packed with traps and puzzles that force players to think beyond their character sheets.

Traps That Do More Than Just Hurt

Not all traps should just deal damage and call it a day. This book divides its collection into four categories:

• Painful Traps – Simple yet effective, these traps primarily cause physical harm.
• Deadly Traps – Reserved for high-stakes encounters, these can outright kill the unwary.
• Disruptive Traps – Designed to cause inconvenience rather than harm, forcing creative problem-solving.
• Complex Traps – Multi-stage contraptions that challenge both player strategy and character abilities.

Each trap comes with details Trigger and Flavor, Result as well as Investigating and Disarming.

Puzzles: Engaging the Mind, Not Just the Sword

Sometimes, the best challenge isn’t a monster with high AC but a riddle that makes players pause and discuss. This book delivers puzzles in three categories:

• Rhymes and Riddles – Classic wordplay and logical puzzles that feel timeless.
• Ciphers – Codes and symbol-based challenges for a more intellectual twist.
• Getaway Puzzles – Obstacles that must be solved under pressure, often in pursuit or escape scenarios.

Each puzzle includes comes with a solution, but a good game master should always be willing to take something that is either close enough or fits, even if it is not the correct solution.

50 Ready-to-Use Dungeon Chambers

Sometimes, you need a dungeon fast, and this book makes it easy with 50 fully detailed rooms ready to drop into any adventure. Each chamber includes:

• A unique theme or challenge
• Room features that interact with players and enemies
• Treasure, secrets, and lurking dangers

These chambers can be combined to create an entire dungeon or used as standalone set pieces.

For those who enjoy improvisation, the book includes a random generator for traps, puzzles, and dungeon elements. If you don’t want to pick a challenge, you can just roll and let fate decide.

Bonus Dungeon Chamber: The Echoing Vault

Description

As the party enters this chamber, they see a massive stone vault resting on a raised dais, covered in arcane sigils that seem to shimmer and shift. Surrounding it are six pedestals, each holding a small stone tablet etched with strange symbols. The room’s walls are covered in deep claw marks, and the air hums with an unnatural resonance, as if something is listening.

The Problem?
This vault can only be opened by speaking the correct word, but the room remembers everything that is said and begins repeating words back at the party—sometimes harmlessly, sometimes dangerously.

The Echo Trap

Each time a character speaks aloud, roll 1d6 and consult the following effects:

The correct word to open the vault is a riddle hidden in the room’s symbols. The answer is inscribed on one of the stone tablets, but the tablets have been shuffled, and picking up the wrong one causes a spectral guardian to emerge and attack.

Possible Solutions & Outcomes

• Players who remain silent can study the symbols and attempt Intelligence (Investigation or Arcana) checks to determine the correct phrase.
• Players who experiment with the echoes might uncover the pattern, using trial and error to isolate the safe words.
• Players who blurt out dangerous phrases may unleash chaos before they solve the puzzle, fighting off summoned creatures, illusory copies of themselves, or worse.
• If they solve it, the vault opens, revealing a cache of ancient treasure, a forgotten relic, or a long-lost secret.

Why This Chamber Works

• It challenges players to think before they speak, adding tension and forcing creative problem-solving.
• The random effects ensure no two groups will experience it the same way.
• It fits into any dungeon, adding mystery and danger without relying on combat alone.
