Crack The Code To Reveal The Sender

An immersive mystery game that begins as soon as your open the envelope!

The Missed Flight


Write, record or snap your secret message – remember, the recipient won’t be able to see this until they crack the code.


We stash your message in our online vault, we pack up your Puzzle Post and we pop it in the actual post.


Once it lands on their doorstep, they have to complete the puzzles inside, log in to our vault and reveal the secret message.

Absolutely fantastic!! Received this as a Christmas present and it provided hours of entertainment. So so clever and well put together! Really enjoyed it so much, would highly recommend, a great gift idea for something a bit different!
