You open the app and the city leans in: cobbled alleys, guildhall façades, and the hush that lives between tram clatter and café chatter. L'Alchimiste sends you into Brussels as a detective of old, piecing together accusations of witchcraft through character-driven puzzles that use streets, squares and details most visitors pass without notice.

You open the app and the city leans in: cobbled alleys, guildhall façades, and the hush that lives between tram clatter and café chatter. L'Alchimiste sends you into Brussels as a detective of old, piecing together accusations of witchcraft through character-driven puzzles that use streets, squares and details most visitors pass without notice.
The game threads fiction through real history — Grand Place’s 17th-century guildhalls, narrow lanes that once witnessed public debate, and urban folklore about alchemists and accusations. Geology shows up in the stones beneath your feet: compacted cobbles and sandstone façades that bear soot from centuries of city life. Cultural touches — multilingual plaques, comic-strip murals, and the Belgian habit of lingering over coffee — add texture to each clue.
Expect 90–120 minutes of mostly flat walking, stopping at waypoints to scan, read and solve. The app guides you; there’s no live guide, so navigation and basic map reading help. Families and mixed-ability groups can move at their own pace, and photos at the end recap the adventure.
Practicalities: bring a charged smartphone, local data or offline maps, and comfortable shoes for uneven cobbles. Start earlier in the evening to avoid peak tourist crowds around Grand Place, and keep an eye on tram tracks when you’re glued to the screen. The game runs daily and can be accessed across a flexible window, so schedule it when you can focus on clues and the city’s small, revealing details.
The experience is designed for about 90–120 minutes, but you can take longer if you explore or stop for breaks.
Yes — the game is family-friendly and physically easy, though some puzzles may require reading or adult help.
You can access the game any time between midnight and 11:30 p.m.; choose a start that suits your schedule and daylight preferences.
It is self-led via the mobile app — there’s no on-site guide, so you navigate and solve independently.
Coddy operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
