Mission SUNSCREEN by Glitch Hunters

London turns into a game board. Mission SUNSCREEN by Glitch Hunters is a City of London walking spy adventure that plays like a treasure hunt, guided by a web app on your phone. You follow a storyline where you’re the hero trying to save the world, with clue after clue pushing you to the next spot.

I love the self paced format, where you can pause and restart as you please. I also love how the puzzles make you look twice at London’s architecture and odd little details you’d normally walk past.

One drawback to plan for: you’ll spend a lot of time staring at your phone, so in heavier areas like weekday lunch it can feel crowded, and you’ll need to watch for cyclists while you’re figuring things out.

Key highlights worth planning for

• Phone guided spy storyline that turns the City into a living puzzle
• Stop to stop flexibility, letting you move at your team’s pace
• Royal Exchange, Leadenhall Market, and the Monument as built in anchors
• About 4,000 steps on foot, with built in breaks for food and drinks
• Team play for 2 to 6 people, with options to split for a head to head race
• Fully wheelchair accessible, so mobility needs don’t have to kill the fun

Mission SUNSCREEN in plain English, the spy game vibe

This isn’t a sit and listen tour. It’s a hands-on London game built around clues, riddles, and puzzles you solve as you walk. A web app on your phone gives the direction and the next challenge, so you’re not relying on a constant stream of spoken narration.

The storyline framework helps the whole thing feel like one continuous mission, not three random photo stops. In practice, you’ll move from spot to spot, solve something at each stage, then get your next objective. It’s a smart way to keep you engaged, because the game mechanics do the work of holding your attention.

And since you can play at your own pace, you’re not forced to sprint. You can linger if a clue takes longer, or slow down if you want to just absorb what you’re seeing between tasks.

Price and time value, what $17.73 buys you

At $17.73 per person for about 3 hours, this game is good value for one main reason: you’re paying for activity time, not just information. You’re getting an organized route across the City, a guided puzzle system through an app, and built in breaks where you can grab food and drinks.

From real experience patterns, these games often land near the lower end if you get moving quickly. One group finished in just under 3 hours, while another took closer to 2.5 hours with a slower start that smoothed out once they got the hang of the flow. Translation for you: plan on around the stated time, but don’t be surprised if your team clicks and finishes faster.

Also, the price is per person, which matters if you’re traveling with friends, siblings, or a family group. It’s easy to split into teams of 2 to 6 without paying for an oversized private coach situation.

Where to meet at Cannon Street and how the route feels

You start at Cannon Street Greater, Cannon St, London EC4N 6AP, and the game ends back at the same meeting point. That matters more than you might think. In a city where you can lose time easily, having a clear start and finish point keeps your day structured.

It’s also near public transportation, which is a win if you’re mixing this with other London plans. And since it’s a private activity, you only share the experience with your group, not a big public crowd.

On your feet, you’re looking at roughly 4,000 steps. That’s a distance you can handle with breaks, but it’s not a “stroll only” activity. If your plan for the day includes lots of other walking, put this early enough so you’re not running on empty by the end.

Stop 1: Royal Exchange Building, starting the puzzle in a real City landmark

Your first anchor stop is the Royal Exchange Building London. Starting at a major, recognizable City site is a smart design choice. You’re orienting quickly, and the area gives the game a sense of place right away.

What makes this stop useful for you is the way puzzles tend to push your attention. Instead of just seeing a facade, you’re hunting for clues in the surrounding details. That’s the main payoff people talk about: you notice architecture and oddities you would normally skip.

A practical consideration here is crowding. The City can be busy, especially on weekdays around lunch. If you’re sensitive to noise and people brushing past you, choose an off peak time.

Stop 2: Leadenhall Market, a natural scene change during the game

Next up is Leadenhall Market. This is the point where the experience often feels like it shifts gears. Market areas change the pace visually and rhythmically, and the game uses that by giving you a new set of tasks to solve.

Leadenhall Market is also a good “team check” moment. By now you’ve started the web app flow, you’ve learned how your team communicates about clues, and you’re figuring out the small habits that save time. Some groups race early. Others take a few minutes to get in sync. Either way, this stop is where momentum tends to decide your finish time.

One small warning based on how the game works: because you’re frequently checking your phone while walking, you’ll want your group to agree on a system. For example, one person can focus on the next instruction while another reads the surrounding clue elements. It reduces bumping and keeps you from doubling back.

Stop 3: The Monument to the Great Fire of London, where the clues pay off

The final landmark stop is the Monument to the Great Fire of London. Big city monuments tend to do one thing well for puzzle games: they act like a strong geographic “map point.” Even if you’re not a London expert, you can orient around the monument area and keep moving with confidence.

This is also where you feel the “save the world” storyline start landing. By this stage, you’ve worked through enough riddles that the game feels like one mission with consequences, not disconnected questions.

If you’re someone who likes to solve things but also wants to look up and take in the surroundings, this is a great stretch. Many puzzle hunts fail because they trap you in your screen. This one tries to keep you engaged with your surroundings too, through the way clues tie to what’s around you.

Walking smart, handling 4,000 steps and built in breaks

The game is on foot and clocked around 4,000 steps. The good part is that it includes built in breaks, where you can grab food and drinks, recharge, and strategize. That’s not just comfort theater. Breaks keep the puzzle part fun instead of frustrating.

For families and mixed age groups, breaks are what make the difference between a tour that feels manageable and one that feels exhausting. One set of ages ranging from 33 to 70 worked well partly because the pace let people reset. Another group with kids ages 12 and 14 finished in under 3 hours, which suggests the breaks plus the game structure do a lot of the heavy lifting.

My practical tip: treat the built in breaks as part of the strategy. When you get stuck, don’t just power through while walking. Stop, reassess the clue together, and pick a direction. You’ll usually solve it faster.

How the app guides you, and how to avoid getting stuck

The game uses a web app on your phone to guide you through the route. You’ll solve clues, riddles, and puzzles that unlock what comes next in the storyline. In real use, the flow is designed to be easy to follow, so you’re not constantly guessing where to go.

If you get really stuck, there’s a way to see the answer. That prevents the classic “we’re done” moment. You might not love using it, but it’s a useful safety net, especially for kids or if you’re playing during a short London window.

One more note from the experience style: the navigation can require you to check your phone frequently. There’s also a preference signal from one review about how text clues might be better than photos for walking in busy central London. That lines up with the reality of City streets: it’s smarter to keep your eyes up when you can, and to move as a team.

Best time to play, when the City makes the game easier

Timing changes the whole feel of this kind of activity. On weekdays around lunch, central areas can get crowded, and since you’re looking at your phone, it can add stress. On weekends, it’s often quieter, which makes it easier to focus on puzzles and your surroundings.

If your schedule allows it, I’d aim for a time when you’re not stepping into peak commuter chaos. The game itself supports breaks, but you’ll enjoy the experience more if you’re not constantly squeezing past crowds while trying to decode clues.

Weather is a factor for any walking game. One group specifically recommended picking a day with good weather, which is a sensible rule. You’re still doing a lot of outside walking.

Team play for families, friends, and coworkers

This game works especially well in groups. You play in teams of 2 to 6 players, and you can split into multiple groups for a head to head challenge. That makes it easy to travel with siblings, friends, or colleagues who want something active but not overly competitive in a scary way.

I like that it gives you different social modes. You can cooperate like a family, or you can race like game night. One group described splitting into boys and girls teams and genuinely racing to finish. It’s exactly the sort of setup that turns a cloudy sightseeing day into a shared story.

For families, it’s also a solid pick because the puzzles are described as clever, with some harder than others. The result is that kids feel included, adults stay engaged, and nobody gets stuck just because they missed one complex step.

Accessibility and practical comfort for your day

The route is fully wheelchair accessible. The game is designed as on foot movement, about 4,000 steps, but accessibility is explicitly supported, which is important for planning.

Service animals are allowed as well. And since it’s close to public transportation, you’re not forced into long awkward transfers with mobility constraints.

If you have mobility needs, I’d still plan your pacing. The ability to pause and restart helps here. It means you can slow down to match your body, without losing the mission.

Small challenges worth knowing, so you’re not surprised

Even with the high ratings, there are a couple considerations that matter.

First, phone time. The design uses your phone heavily, and that can feel distracting if you want a purely scenery based walk. If you love puzzles and don’t mind screen checking, you’ll be fine. If you hate looking down constantly, it might annoy you.

Second, cycling and busy streets. Because you’re focused on reading and looking around for clues, keep your situational awareness high. One review specifically flagged cyclists, which is just common sense in the City.

Third, starting slower is normal. One family noted a slow start the first time, which is likely because teams need a minute to understand the app flow. Once you’re rolling, the experience tends to move smoothly.

Should you book Mission SUNSCREEN by Glitch Hunters?

Book it if you want London that feels like a game, not a lecture. I think it’s a great fit for people who like puzzles, enjoy walking at a manageable pace, and want to see the City’s architectural details through a mission style route. It’s also an easy recommendation for families with teens and for mixed age groups because the experience structure and built in breaks keep everyone in the loop.

Skip it if your ideal day is low tech sightseeing, minimal screen time, or quiet wandering without any “work” element. If you already know you hate phone guided experiences, you’ll probably feel annoyed more than entertained.

If you go in with the right mindset, Mission SUNSCREEN is a clever way to turn a few hours in the City into a story you actually remember.
