Radio puzzle Hidden in the room is the correct AM station. When you land on the correct station a specific audio clip plays to lead you in your journey!

Door Knocker

The door knocker puzzle is a very flexible puzzle. It can be programmed to support any style of knock at any length. The speed of the knock does not matter!

The knocker was used in tandem with a magnetic lock. When the correct knock is used the door unlocks and opens itself.

Piano

This was a custom built installation for a local Escape Room. It is a fully working Piano that the users can play for fun. It is until the user inputs in the exact combination of keys (hidden in the room) will it trigger a success. In this instance the success releases a magnetic lock & plays a custom sound.

Breaker Box

The breaker box is a fully programmable circuit box. When the correct input is made a success light is turned on and a relay is fired triggering any prop, from a Light to a magnetic lock on a door.

In this above example, the breaker box is used in tandem with a Bingo board. When the correct circuits are made, numbers on the bingo board are illuminated.

Room Escape Timer

This is a custom built Room timer management system with the ability to communicate inside the room with text.
