If you’re looking for a fun, engaging way to explore the streets of Liège, Belgium, the Walter Case escape game offers a unique twist. This private, self-guided adventure takes you on a detective journey through the city’s historic streets, solving puzzles and engaging with the environment in a way that’s both entertaining and insightful. It’s a great choice for groups of friends or family wanting a different kind of sightseeing experience, all for around $23 per group—quite reasonable for the two-and-a-half-hour adventure.
What makes this experience stand out is how it combines storytelling, interactive puzzles, and a city tour into one package. I especially appreciate how flexible it is—you control the route, decide which suspects to question, and explore at your own pace. From the reviews, it’s clear that many find it boosts their appreciation for Liège’s sights without feeling like a typical tour. Plus, you get a fun, photo-filled summary at the end to remember your detective work.
Two things stand out as particularly appealing: First, the storyline involving blackmail and a ticking bomb adds a real sense of urgency and excitement—especially with only two hours to save the day. Second, the game’s flexibility and the support offered—with 24/7 online assistance—helps keep things running smoothly, even if your phone battery starts to wane. One practical tip from reviewers: bring an external charger because phones tend to drain quickly during the game.
However, a possible consideration is that smartphone and battery management are crucial—this isn’t a tour you can do without your device fully charged. Also, since food and drinks aren’t included, you might want to plan for a snack break afterward.

How the Story Unfolds: Blackmail, Suspense, and a Race Against Time

The narrative kicks off with you stepping into the shoes of a private detective investigating a seemingly mundane case of blackmail against a billionaire CEO. But things quickly escalate: you learn that a bomb has been planted somewhere in Liège, with just two hours on the clock before it explodes. The stakes are high, and you’re the only one with enough leads to stop it.
Throughout the game, you’ll question suspects, search for clues, and make decisions that influence how the story progresses. As one reviewer, Charles, put it, “The story is well built, and the tour allows you to discover the city without physical strain.” The game feels more like an episode of a crime series than a typical city walk, adding layers of excitement. The tension increases as the countdown ticks down, creating a sense of urgency that keeps everyone engaged.
What to Expect During Your Detective Mission

From there, the game guides you through various parts of Liège, such as the Place du Marché and other notable spots, all while integrating puzzles and story elements.

An important aspect is how much you look around and pay attention to your surroundings. The clues hinge on visual details, street signs, and small local features—so don’t rush through. As AnneLise noted in her review, “It’s a good way to discover the city,” adding that bringing multiple phones and an external charger is practical because phones tend to drain quickly.
