Moriarty’s Game: The Professor’s Invitation by HiddenCity

A Fun and Unique Way to Discover London’s West End

If you’re tired of the usual sightseeing routes and looking for something a little different in London, Moriarty’s Game: The Professor’s Invitation by HiddenCity might just hit the spot. This self-guided scavenger hunt takes you through the streets of Marylebone and beyond, challenging you to solve riddles and puzzles inspired by Sherlock Holmes’ infamous foe, James Moriarty. It’s a smart mix of adventure, puzzle-solving, and sightseeing that appeals to a wide range of travelers.

What really makes this experience stand out are two things: first, you get to visit hidden corners and lesser-known sites in London that don’t typically make it into guidebooks, and second, the flexibility to go at your own pace. Whether you’re with friends, family, or just on your own, this tour offers a playful way to explore the city while engaging with a compelling story.

That said, a potential consideration is that this is not a guided tour with a person—it’s all on your phone and your own timing. If you prefer a more structured, guided experience, this might feel a bit too independent for you. It’s best suited for those who enjoy a bit of puzzle-solving and are comfortable navigating with a mobile device.

This tour seems perfect for Sherlock Holmes fans, escape room enthusiasts, or anyone looking for a different way to see London’s neighborhoods. It’s especially appealing if you’re traveling with a group that enjoys teamwork and storytelling.

Exploring the Itinerary in Detail

Starting Point: Marylebone

Your adventure kicks off at Marylebone High Street, a charming and lively part of London that’s a bit less touristy than nearby areas like Oxford Street. Here, you’ll download your clues and get ready to follow the trail.

The Treasure Hunt Across Marylebone

For about 3 to 4 hours, you’ll wander through the streets, solving riddles sent directly to your phone. The game is designed to be interactive and story-driven, with players taking on the role of detectives trying to outwit Moriarty himself. The puzzles range from riddles to logical challenges, and the clues often lead to hidden corners and landmarks that you might otherwise overlook.

Hidden Gems and Local Flavors

As some reviews point out, you’ll get to enjoy the small streets and lesser-known spots that give London its charm. The game encourages you to look beyond the obvious and appreciate the city’s hidden details. Many players enjoy the way the experience combines sightseeing with storytelling, making even familiar neighborhoods feel fresh and intriguing.

Break Points and Refreshments

One of the nice touches is that there are designated break points where you can pause the game for some food or drinks, though you’ll need to cover those costs yourself. This makes it easier to stretch your legs or refuel without feeling rushed.

End Point and Flexibility

The tour wraps up in Mayfair, another vibrant part of London, giving you the chance to extend your explorations or head back to your accommodation. Since the experience is entirely self-guided and can be paused anytime, you can tailor the timing to your schedule.

Why Travelers Love This Experience

Many reviews highlight the fun and engaging nature of this activity. One reviewer noted, “We loved it. The game took us all over a couple of neighborhoods in London and to several cool places. We enjoyed looking at all the sites along the way and seeing some of the small streets and out-of-the-way places.” This indicates that the tour isn’t just about solving puzzles—it’s also about discovering the city’s quieter, charming corners.

Another consistent theme is the knowledgeable storyline and how well the puzzles are designed. Although there’s no official guide, players feel they’re part of a Sherlock Holmes mystery, which makes the experience immersive and fun.

Considering the Price and Value

At around $40.49 per person, the experience offers a lot of value, especially considering the duration and the interactive nature. When you compare it to traditional guided tours or escape rooms, which can cost similar or more, this option provides a unique outdoor adventure that’s both affordable and flexible.

However, it’s worth noting that since it’s self-guided, you’re not paying for a guide’s expertise or commentary. The value lies in the story, puzzles, and the opportunity to explore at your own pace. If you’re a fan of Sherlock Holmes, riddles, or quirky city adventures, this is definitely worth considering.

Practical Details That Matter

• Duration: 3 to 4 hours, perfect for a half-day activity without feeling too long or too short.
• Location: Starts at Marylebone, ends in Mayfair—both central and easy to reach via public transport.
• Group size: Best for teams of 2-6 players, but you can split larger groups into smaller teams for some friendly competition.
• Booking: Most travelers book about 19 days in advance, so plan accordingly.
• Accessibility: Most travelers can participate, and service animals are allowed.
• Cancellation: Free cancellation up to 24 hours before the start, providing peace of mind for last-minute plans.

What’s Noteworthy About the Experience

While many think this is a great way to see London differently, it’s important to go in with expectations about the independence involved. This isn’t a guided walking tour with a knowledgeable guide telling you stories—it’s a story-driven puzzle game delivered via your phone. If you enjoy solving riddles and exploring at your own pace, you’ll love the freedom it offers.

Some reviews praise the knowledgeable puzzle design, making the story feel authentic and engaging. But since it relies on your phone and self-navigation, you’ll need to be comfortable with a bit of tech and map reading.

Our Take: Who Should Try This?

This experience is particularly suited for Sherlock Holmes fans, puzzle lovers, and curious explorers who enjoy storytelling and city adventures. It’s a wonderful option for groups or families who can work together, especially if you’re tired of crowded museums or guided tours.

If you’re traveling with kids, they might enjoy the game if they’re comfortable with puzzles and walking, but keep in mind it’s more suitable for older children and teenagers. If you’re after a very structured or guided tour, this might not be the best fit.

Overall, it’s a creative way to get a feel for London’s neighborhoods while participating in a playful, interactive story.
