Working alongside our parent company 72Point, we worked with Heathrow Express to create a mind boggling puzzle to get them some visual press coverage.

The puzzle features 3 different tracks that look like they lead to the airport. The challenge is to find the only track that actually does go to the airport. (The correct answer is track B!)

In addition to making The Mirror in print (a first for our puzzles), it also made on various news sites including The Mirror’s site.
