Important: You cannot access your gamecode via the Tripadvisor ‘ticket’ link. It will be manually generated and sent to you by message after booking.
No time slot needed — play any day, any time during daylight hours. All you need is a smartphone with a web browser.
The game is designed for adults or teens with an interest in history, walking, and light problem-solving. It’s an adventure walk — not a race — so take your time. Pause for a drink, explore side streets, or rest when needed. Use the /ROUTE, /HINT, or /SKIP commands to get help or move faster.
The route is 5km, starts and ends at Trafalgar Square, and is fully wheelchair and buggy accessible via six step-free detours.
Once you activate your gamecode and begin, you’ll receive a message that sets the scene and sends you on a journey across London using visual clues and location-based tasks. Every step brings you closer to the final solution — if you can spot it.
Expect moments of doubt, glimpses of truth and plenty of intrigue. All you need is a phone and a steady nerve.The game is available in 11 languages: English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, and Arabic.
There is no guide to meet you — your guide is your phone. Your Viator booking reference (BR-…) is your ticket. Go to the start point for the trail, open play.sidewalks.co.uk on your phone, tap "Booked on Viator?" and enter your reference. Everyone in your group should do this.
