The square at Arsenaalplein hums with ferry whistles and the low, steady motion of the Western Scheldt — a city that pushes you toward questions as easily as the tide pushes barges. Here you pick up a virtual calling card: your phone, the Loquiz app, and a plot that unfurls across streets and quay-side alleys. The case of Balthasar drops you into a detective’s cadence: read, observe, puzzle, move.
Terneuzen’s past is practical and maritime — a 19th–20th century port town that grew around shipyards and trade. Its cobbled streets and warehouse facades keep the memory of cargo and crossings visible, and local culture still orbits the river; cafés and small shops make good pit stops between clues. Geology matters here too: the Western Scheldt estuary carves channels and creates a working waterfront where currents and tides shape the town’s pace.
The game is story-driven and family-friendly, playable in English and several European languages, and takes about two hours at a relaxed pace. Practicalities are simple: start at Arsenaalplein, one device per group (1–4 players), and you can begin anytime on your booked date. Expect walking on flat pavement, photo tasks, code-cracking, and digital characters who nudge you toward the next lead.
Bring a charged phone, a power bank, and comfortable shoes. Start earlier in the day for softer light and fewer interruptions, and factor in weather — wind off the estuary can flip an umbrella quickly. The experience is about observation: slow down, read the street, and let the city reveal the clues.
The official start location is Arsenaalplein in central Terneuzen; the instructions email explains check-in and how to launch the Loquiz session.
Plan for about two hours at a relaxed pace; faster teams can finish sooner, and you can pause and resume as needed.
One ticket covers a group of 1–4 players using a single device; buy additional tickets for larger groups.
Difficulty is easy and family-friendly, but the route uses public streets and some uneven pavements — check mobility needs before starting.
City Game operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
