404

Solve the puzzles and reveal the conspiracy. If you enjoy riddles, brainteasers or escape room games, 404 is for you:

• A mysterious book, packed with over 65 hidden messages
• No puzzle instructions - you must work out what to do
• Every code has a unique design and a unique solution
• Reveal the story as you solve
• Hints are available for every puzzle, should you need them

404 can be solved entirely offline but you can verify your solutions on the book's dedicated website, which you can also reach by scanning the QR barcode on every puzzle page. The website features intelligent checking, to encourage you and provide assistance if you are on the right path but haven't quite found the answer.
