Puzzle Post Escape Room in an Envelope - The Blunder

Are you ready to be thrown into a world of secret messages, voyages and drama? Each Puzzle Post Escape Room game begins as soon as you open the envelope...

In 'The Blunder', James Tenison has been on an adventure through China when he realises what a terrible mistake he's made back home.

An excruciatingly embarrassing (and potentially career-ending) message meant for someone else is due to be delivered to his whole company unless you stop it.

Solve all nine puzzles that James has left you, break into the online vault where the message is hidden and delete it before it's too late.

You will certainly need to think outside the envelope!
