Liège escape game: Solve puzzles while exploring the city

A two-and-a-half-hour detective hunt through Liège's streets, puzzles and suspects

The Walter Case is a self-guided urban escape game played on the streets of Liège using a mobile app. You investigate a blackmail plot, hunt for a hidden bomb and choose which suspects to question and which neighborhoods to search, with the story shifting based on your decisions. The game runs for about two and a half hours and includes 24/7 online support, a city tour woven through the gameplay, and a photo summary of your adventure at the end.

The experience

You arrive in Liège with a free afternoon and a smartphone. The Walter Case starts the moment you open the app: a billionaire CEO is being blackmailed, and intelligence suggests a bomb is hidden somewhere in the city with two hours on the clock. You become the private detective tasked with finding it. The game sends you into the streets to search specific locations, examine your surroundings for clues, and piece together which leads matter. Every choice you make (which suspect to interrogate, which route to take through the neighborhoods, which area to search first) shapes how the investigation unfolds.

The app guides you from one puzzle to the next, but you decide the path. You'll walk through different parts of Liège, noticing details you might otherwise miss: a storefront, a street corner, a public space that holds a clue. Solving each puzzle unlocks the next lead. The countdown is real in the game's logic, even if you can take as long as you need in actual time. Your team works together to decode the riddles, spot the hidden details and stay ahead of the fictional clock.

When you finish, the app generates a summary with photos from your adventure: a record of where you went and what you solved. Support is available around the clock if you get stuck. The game stays valid for up to three years, so you can return to Liège and replay it, or send the link to friends who want to try the same case.

Top questions

What languages is the tour guided in?

Live guide in English, Spanish, French, Italian and Dutch.

Can I play the Walter Case with my family, or is it only for groups of friends?

The Walter Case works for any team: family, friends, coworkers or a mix. You walk together, solve puzzles as a group and decide together which leads to follow, so it suits any combination of people who want to investigate together.

Do I need to know Liège before I start, or will the game teach me the city?

The game itself is the tour. You'll visit different neighborhoods and landmarks as the investigation sends you there, so you learn the layout and discover parts of the city while solving the case: no prior knowledge needed.

What happens if I get stuck on a puzzle?

Online support is available 24/7 to help you move forward if you hit a wall. You can contact them through the app whenever you need a hint or clarification.

How much walking is involved, and can I do this if I use a wheelchair?

The game involves walking around the city to reach different puzzle locations. All areas and surfaces you'll visit are wheelchair accessible, and transportation options are available nearby if you need them.

Do I need to bring anything besides my phone?

You'll need a smartphone with the app installed and enough battery to last the two and a half hours. Food and drinks are not included, so bring water or plan a café stop if you want refreshment during the game.
