Here we have something new. A fully 3D interactive D&D map which is a fully interactive puzzle for your players.

This is based off this reddit post here

The Puzzle
At the center of a room there is a 20’ by 20’ lowered section in the floor, divided into 16 square pressure plates (4x4). The pressure plates are in no way concealed or disguised -- they are meant to be seen.

A spell or other effect that can sense the presence of magic, such as detect magic, reveals an aura of evocation magic coming from the pressure plates.

Applying at least 100 lbs of force activates a plate. Removing the weight deactivates the plate. Players will probably use their own body weight to activate plates, but are not required to.

In the center of each pressure plate, a glowing glyph appears based on the number of activated plates adjacent to it. Diagonally-adjacent plates do not count.

The glyph that appears is as as follows:

Scroll: 1 activated plate is adjacent

Sword: 2 activated plates are adjacent

Throne: 3 activated plates are adjacent

If there are 4 adjacent activated plates, no glyph appears (and any existing glyph disappears). Boom

The Solution

The puzzle is solved when all of the following conditions are met:

There are at least 3 Sword glyphs (easy mode: require only 2)

There are at least 3 Scroll glyphs (easy mode: require only 2)

There are an equal number of Sword and Scroll glyphs

There is exactly 1 Throne glyph

The text the players found earlier is a clue to these conditions.


When the puzzle is solved, all glyphs disappear and the pressure plates no longer react to weight. You can decide what happens as a result based on the needs of your dungeon or area. It could be a forcefield bridge appearing, secret chamber opening, door unlocking, or anything else you need.

For my campaign, blue flames appeared surrounding the pressure-plate platform according to the number of players on it. Once all players got on, it solidified and lowered into the cavern beneath like an elevator.


Example Solutions

X's indicate activated pressure plates.

The Danger
Every carrot needs a stick!

If you're players stand in a way that all 4 are adjacent to a single plate. The plate will erupt in flames damaging all surrounding players. The amount of damage is up to you. I would go with D6 per level of fire damage with a DC 14 Dexterity saving throw. Half damage on a success.


If at any point there is more than 1 throne glyph, the room begins spawning mobs to combat the players.

For my session I used a D6 Table. With the following options. My party has 6 level 8 players so keep take that into account before you drown your players in mobs they can't handle.

D1 -- 4x Skeleton / 2x Skeleton Alchemist
D2 -- 6x Strahd Zombie
D3 -- 4x Wight
D4 -- 6x Mummy
D5 -- 1x Banshee
D6 -- 2x Greater Zombie
