Interactive electronics
Reliable brains and senses for props that notice, decide and respond without exposing the technical machinery to the player.
PF–01 Independent puzzle engineering · UK
Custom escape room props & electronics We make impossible ideas behave.
Bespoke escape room props, interactive electronics and team games, designed from the first spark, engineered for the real room, and built to reset for the next crew.
ESP32 + microcontrollers
Sensors + physical controls
Wired + wireless systems
Mechanical integration
Made for UK projects
Your idea does not have to fit inside a catalogue.
Maybe it is a bomb-defusal challenge that makes a whole team sweat. A crackling Morse radio that hides a code in plain sound. Or a wall, case, console or curious object that reacts exactly when a player has earned it.
PuzzleFoundry joins the electronics, code, mechanics and player experience into one purposeful build. You bring the moment you want to create; we work out how to make it real.
Capabilities / A–D
One workshop.
Every moving part.
Fewer hand-offs, fewer mystery boxes. We can take responsibility for the full interaction, from the thing a player touches through to the logic, signal and physical response behind it.
Control & connectivity
Custom room-control systems can link props, track puzzle state and give game masters clear resets, manual overrides, hint triggers and show cues. Wired, wireless or hybrid is chosen around the real room.
Physical mechanisms
Locks, latches, movement and tactile controls integrated with the electronics, enclosure and practical reset flow.
Experience integration
Puzzle logic, feedback, fail-safes, game-master overrides and reset behaviour shaped into a system your team can actually run.

01
Past build · Team challenge
Bomb-defusal game
A tense, multi-stage physical game built around clear controls, timed logic and the delicious pressure of having everyone shout at once.
- Interaction Multi-player coordination
- System Physical controls + timed logic
- Design goal Tension without confusion
02
Past build · Electronic prop
Old-school Morse radio
A tactile encoder and decoder wrapped in the language of vintage radio: knobs, sound, signalling and just enough mystery to make a message feel discovered.
- Interaction Encode + decode
- System Audio + microcontroller
- Design goal Character with clarity
The next entry could be yours. We are interested in the awkward, ambitious and “is that even possible?” briefs, not just another keypad in a box.

From first sketch
to final reset.
The process flexes around the job, but the questions stay practical: what should players feel, what can fail, who resets it, and how will it survive the hundredth run?

01
Brief
Define the moment
We turn the player experience, venue, constraints and budget into a buildable technical brief.
Output / agreed direction -
02
Prototype
Prove the tricky bit
The uncertain interaction, mechanism or signal path gets tested before polish makes changes expensive.
Output / working proof -
03
Build + playtest
Make it earn trust
Hardware, firmware and mechanics come together, then get challenged by realistic use and reset cycles.
Output / tested system -

Finish + handover
Fit the real world
We finish around the environment and plan the controls, documentation and practical handover.

Reset route mappedBypass W2 mapped
A useful game-master view, scoped around how the room is actually run.
The magic should feel mysterious. The operation should not.
Interactive props live a harder life than ordinary gadgets. Different players pull, press and improvise. Staff need fast answers. Every new group expects the same moment to work.
-
01
See what the room is doing
Live puzzle status and clear diagnostics can help staff act before a small fault becomes downtime.
-
02
Reset and recovery are designed in
Known states, manual bypasses and predictable power or network recovery are considered from the start.
-
03
Serviceable beats sealed mystery
Accessible internals, replaceable parts, wiring information and a practical handover matter after install.
Where ideas become interactions.
Escape rooms
Signature props, room control, puzzle upgrades and unusual centrepieces.
Team building
Portable or installed challenges built around communication and shared decisions.
Visitor experiences
Hands-on exhibits and reactive objects that reward curiosity with a memorable response.
Events + activations
Branded interactive games, portable multi-team challenges and memorable audience participation.

Ask us something elseWhat kinds of escape room props can you build?
One-off electronic, mechanical and connected props: sensor-driven puzzles, physical controls, timed challenges, lighting and audio feedback, show-control systems, portable team games and unusual ideas that cross several disciplines.
Can you create a one-off prototype?
Yes. A project can begin with a focused proof of concept before moving into a complete, serviceable build. That is useful when an interaction, mechanism or wireless setup needs to be proven first.
Can you work with an existing room or prop?
Often, yes. We can assess an existing room, prop or game and propose a retrofit, replacement controller or new interaction while working around its space, reset and maintenance constraints.
How much does a bespoke build cost?
There is no useful one-size price: the mechanism, electronics, fabrication, finish, installation and number of units all matter. Your brief does not need to be technical; share the intended player moment, venue, timescale and working budget, and we can suggest the right level of build.
How early should we get you involved?
Early enough to shape the concept is ideal, especially where electronics and mechanics affect scenery or room layout. A developed idea is welcome too; we will start by identifying what is fixed and what still needs proving.
Can accessibility requirements be designed in?
Yes. We can discuss accessibility needs at the start and design for them explicitly: visual alternatives to audio, shape or texture alongside colour, readable feedback, reachable controls and adjustable timing. The right approach depends on the intended players, venue and experience.
Do you work on projects across the UK?
Yes. PuzzleFoundry welcomes enquiries from across the United Kingdom. Discovery and design can happen remotely, with delivery, installation and support planned around the project.
