You step off the market square and the city rearranges itself into clues: cobbles that shift underfoot, the Belfry watching like a patient jury, alleys that dare you to choose a direction. The Walter Case drops you into Mons as a ticking investigation—an imagined blackmail spirals into a race to find a hidden bomb within 150 minutes.

You step off the market square and the city rearranges itself into clues: cobbles that shift underfoot, the Belfry watching like a patient jury, alleys that dare you to choose a direction. The Walter Case drops you into Mons as a ticking investigation—an imagined blackmail spirals into a race to find a hidden bomb within 150 minutes. Your phone is the only badge you need; choices you make alter the route, suspects, and puzzles.
Mons sits at the crossroads of Wallonia and French Flanders, its streets shaped by centuries of trade, coal mining and military history. The belfry—UNESCO-listed—keeps the same skyline the game uses as a landmark while Baroque and neo-classical facades mark old money and industrial reinvention. Beneath the touristic gloss there are working neighborhoods and parks where urban wildlife slips past: kestrels lift from church ledges and red foxes haunt the outskirts at dusk.
Practicalities are straightforward: the self-guided experience lasts about 2.5 hours and supports teams up to six. The app leads you between 35–45 missions with 24/7 online support; public transport and accessible routes mean most groups can join. Wear comfortable shoes, carry a portable charger, and factor in weather—Mons’ spring and autumn can shift from sun to showers in an hour. Start early to avoid crowds on the Grand-Place, and leave time after the game to explore museums or a local café. This is a puzzle-first way to see Mons: fast-paced, civic, and surprisingly local—no props required, just curiosity and a charged phone.
The app provides the precise start point in central Mons—typically around the Grand-Place—and the finish is reached by following in-app directions as you complete missions.
The activity supports teams of up to six players using a single booking and device per team.
Yes—routes are chosen to be accessible where possible and public areas used in the game are generally wheelchair- and stroller-friendly.
