Book Your Mission

Stop a Villain. Save London. Look Really Closely at Buildings.

Professor Blacksheep is building S.U.N.S.C.R.E.E.N. — a mind-control satellite disguised among the City's skyscrapers. His Reality Rewriters have hidden rocket silos inside office blocks and surveillance drones behind monuments. A defector known only as "K" is feeding you intelligence, but the clock is ticking.

Your weapon? The P.H.O.N.E. — a Portable Hub for Optimal Navigation and Espionage. With it, you'll match window patterns on Cornhill, crack a shield sequence at the Royal Exchange, trail coded signs through Leadenhall Market, and ultimately shut down the satellite near the Monument.

Secrets Hiding in Plain Sight

A City Built on Secrets

The Royal Exchange has stood at the heart of London's commerce since 1565 — and its courtyard lamp posts still bear the shields of the twelve Great Livery Companies. Leadenhall Market has occupied the same site since Roman times, its ornate Victorian ironwork concealing centuries of history beneath its arches.

What Everyone Else Walks Past

Every day, thousands of commuters stream past heraldic shields mounted on lamp posts, inscriptions set into the pavement, and coats of arms carved into facades — without a second glance. During Mission SUNSCREEN, those overlooked details become your puzzle pieces. You'll never look at a drain cover or a Victorian column the same way again.

🔥 1666: Great Fire of London — The Monument still marks where it started
🏪 Roman era: Leadenhall Market has occupied this site for nearly 2,000 years

Clues You'll Decode Along the Way

  • The twelve Livery Company shields guarding the Royal Exchange courtyard
  • Pavement inscriptions near the Monument that spell out a hidden word
  • Leadenhall Market's ornate signs — each one hiding a letter of a code
  • A "London's Burning" nursery rhyme wired into a circuit-board cipher
  • A Cornhill statue whose silhouette, accessories, and plaque each hold a key
  • Building facades near The Gherkin that double as combination locks
"When a man is tired of London, he is tired of life; for there is in London all that life can afford."

What Agents Say

★★★★★

"Best team activity in London"

"We did this for a work team-building day and it was brilliant. The puzzles are genuinely clever — you have to really look at the buildings around you. We found details in the City we'd walked past for years without noticing."

— Sarah M. · Team of 5, March 2026
★★★★★

"Like being in a spy film"

"The storyline is fantastic — decoding statues, cracking combination locks on building facades, the whole thing feels like you're actually on a spy mission. The Royal Exchange puzzle was incredible."

— James & Family · TripAdvisor, February 2026
★★★★★

"The Royal Exchange puzzle blew our minds — we must have walked past those lamp post shields hundreds of times and never looked twice. Genuinely one of the cleverest things we've done in London."

— Agent Recon, Glitch Hunters
★★★★★

"Brought my parents over from Canada and they loved it. We hit The Gherkin, Leadenhall Market, the Monument — felt like a proper London tour but with a spy plot holding it all together."

— Agent Maple, Glitch Hunters
★★★★★

"We did this for my hen party — six of us racing around the City cracking codes. The bit where you realise The Gherkin is the villain's satellite had us crying with laughter. Finished up at The Candlemaker. 10/10."

— Agent Veil, Glitch Hunters

Frequently Asked Questions

Where does the mission start?

The mission starts near Cannon Street station in the City of London. After booking, you'll receive exact starting coordinates and instructions. The nearest Tube stations are Cannon Street, Bank, and Monument — all within a 5-minute walk.

Can we play at any time of day?

Yes! The game is available 24/7 — you can start whenever you like after booking. However, we recommend playing during daylight hours (especially in winter) as you'll need to observe architectural details on buildings. Weekends tend to be quieter in the City, giving you more space to explore.

How many people can play?

Teams of 2-6 players work best. Everyone plays on the same team using your phones as spy gadgets. For larger groups (corporate events, hen/stag parties), you can book multiple teams who start at the same time and race each other — we've had groups of 50+ playing simultaneously!

What devices do we need?

You'll need at least one fully charged smartphone per team (we recommend one per person for the best experience). The game runs in your phone's web browser — no app download required. Make sure you have mobile data or the ability to load web pages.

Is the route accessible?

Yes! Mission SUNSCREEN has a step-free route option, making it our most accessible outdoor adventure. The City of London's flat streets and wide pavements are suitable for wheelchairs and pushchairs. All puzzle locations are visible from ground level.

Can we take breaks during the game?

Absolutely. There's no time limit, so you can pause whenever you like — grab a coffee, take photos, pop into Leadenhall Market for lunch, or stop at any of the City's many cafes and pubs. The game picks up right where you left off.

Is it suitable for children?

Yes! Families love it. Children aged 8+ can engage with most puzzles, and younger kids enjoy the spy storyline and exploring the City. The route is pushchair-friendly. We recommend at least one adult per team to help with some of the trickier ciphers.

Do we need escape room experience?

Not at all. The built-in hint system guides you if you get stuck — no puzzle expertise required. The game is designed to be challenging but achievable for everyone. First-timers often tell us it's what got them hooked on puzzle games!

How is this different from the Canterbury mission?

Mission SUNSCREEN in London is a completely different adventure with unique puzzles, a different storyline, and the City of London as your playground. Canterbury's "Mission Save The Word" explores Chaucer's legacy through medieval streets, while London's mission is a full spy thriller involving satellite security, encrypted statues, and hidden codes across iconic landmarks. If you loved one, you'll love the other!

Where should we meet before starting?

We recommend meeting at Cannon Street station — it's the closest station to the starting point and has cafes nearby if you want to grab a drink before you begin. From there, it's a 2-minute walk to the exact starting coordinates you'll receive after booking.

Your Mission Awaits, Agent

Professor Blacksheep's satellite won't shut itself down. Assemble your team, charge your phones, and report to Cannon Street. The City's secrets are waiting to be cracked.
