Play detective through Liège’s streets in The Walter Case, a self-guided urban escape game that blends architecture, local history and timed puzzles. Solve clues with friends as the city around you becomes both setting and suspect.
You step off Place Saint-Lambert into a city that talks back: tram bells, the Meuse sparking beyond low stone quays, and narrow streets that hide clues between bakery windows and wrought-iron balconies. The app lights up — a bomb is rumored to be ticking somewhere in town, and you have two hours and a half to chase leads, question suspects and choose the route that will defuse the plot.
Verified experiences and guided adventures in the surrounding area.

You step off Place Saint-Lambert into a city that talks back: tram bells, the Meuse sparking beyond low stone quays, and narrow streets that hide clues between bakery windows and wrought-iron balconies. The app lights up — a bomb is rumored to be ticking somewhere in town, and you have two hours and a half to chase leads, question suspects and choose the route that will defuse the plot.
Liège wears its history on its facades. Once a Roman settlement turned Prince-Bishopric and later an industrial hub, the city’s layered past shows in limestone buildings, river-carved quays, and post-industrial promenades along the Meuse. The Walter Case plays with those layers, sending you through pedestrian lanes, public squares and riverside stretches while asking you to read architecture and street life as evidence. The story adapts to your choices: decide who to pursue, where to search, and which clues to trust.
Practical edge: the game is self-guided on your smartphone, designed for roughly 150 minutes of walking and problem-solving; it’s accessible and stroller/wheelchair friendly in most sections. Expect cobbles and urban steps, intermittent crowds, and weather that can shift quickly — plan with layered clothing and a charged phone. Use public transport to begin and end at central points, and allow extra time if you want to linger at cafés or museums afterwards. Bring a power bank, split tasks among teammates, and keep an eye on the app’s clock — the story tightens as the minutes fall.
