Run your whole escape room from the Game Master's computer

Timer, clues, room displays and automations, live on your local network. And with BOOKING, every booking sets up the room.

MASTER installs on the Game Master's computer. On your phone you can look around here and download it on the PC later.

This is an interactive demo of the MASTER console and it needs JavaScript to work. You can also download the app for free and try it on your computer.

Features

Everything that happens in the room, on a single screen

The Game Master console

  • A control bar always in view: Idle → Ready → Playing → Concluded
  • Timer with pause and more or less time
  • Alerts and background music

Text, audio and video clues

  • To one screen or to all of them
  • Clue libraries in as many languages as you like
  • Templates that fill themselves in with each player's name

Room displays your way

  • Colours, fonts and an image or video background
  • Several screens at once
  • A final win or lose screen

Runs on your local network

  • No internet needed in the room
  • No hardware needed: blocks are optional
  • In six languages, and it updates itself
With BOOKING

Every booking sets up the room

Press “Ready” on the next group's booking: the language, the players, their names and the answers arrive as variables. When the game ends, the result goes back to BOOKING.

Automations

Your room on autopilot, no programming

“When this happens, do that”: you build it with blocks, like a sentence. No code and no need to call an integrator.

  • Guided modes for the classic puzzles: Sequence, List, Simon Says, Connect the Wires and Cut the Wires
  • They can end the game and add or take away time
  • They use the inputs and outputs of the hardware blocks: sensors, magnets, lights and sound
With BOOKING

Press Ready and the room already knows who is coming

The language, the players, their names and the booking's answers load as variables, ready for your clues and automations. And the clue language switches by itself.

  • Bookings for today and the next 7 days, in the Bookings tab
  • If the internet goes down, it carries on with the last saved list
  • When the game ends, BOOKING gets the result and the game times
Clues

Clues that call each player by name

Type {jugador_1} in the clue and, when you send it, it is replaced with the name that came with the booking.

  • Text, audio or video, to one screen or to all of them
  • One library per language: with Ready, it switches to the group's language by itself
  • Or write the clue on the spot, from the console

Questions

About MASTER

Do I need hardware?

No. MASTER works on its own. The hardware blocks add automations with your room's props.

Does it work without internet?

Yes. The game runs on the room's local network. Internet is only needed to update the app and to get the bookings from BOOKING; offline, it carries on with the last saved list.

Does it work on Mac or Linux?

Today only on 64-bit Windows 10 and 11.

Does it update itself?

Yes: it updates itself, it is free and what you tell us decides what comes next.

Is there any warning when installing it?

Yes: Windows shows SmartScreen because the installer is not signed yet. You get past it in three clicks, and we explain how on the Download page.
