50 Clues is an immersive puzzle game that offers the experience of an escape room but played at home. Combine objects, solve puzzles and decipher codes to complete the story – with the aid of a web app.

The Pendulum of the Dead is the first episode of the murderous ‘Leopold’ trilogy. Help Maria escape from the hospital to find her son, before it’s too late…

Contains graphic violence. Unsuitable for children.

What’s in the box?

  • 54 oversized cards

How to play:

To begin you will need a pen and paper and a smartphone or other internet enabled device.

Take the deck of cards and check that all the cards are in the right order and upside down with the number one card at the top.

Then turn the top card over. Card two is a reference card and card three gives you the backstory to the events in the game. The text should be read aloud so that everyone involved can follow.

From here on out, follow the instructions on the cards to solve the puzzles and use the web app to progress the story further with more hints and clues.

Get ready to be immersed and work together to unravel the mysteries that follow!


Continue the adventure with Part 2 and Part 3 in the 50 Clues series.

Each game can be activated 30 times.
