Your briefing

Zurich, winter 1943

A neutral city, gleaming and quiet — and beneath it, the busiest crossroads of secrets in Europe. A banker who has seen too much wants out. Before he vanished he split a record — the Turicum Ledger — among five trusted contacts across the old town.

Find all five. Learn who really held the gold. Then open the vault.

You play a newly recruited agent. Your kit is your edge; your handler is one scan away. And somewhere on these streets walks Der Habicht — the Hawk.

How it works

A real kit. Real streets. Real clues.

✦ ✦ ✦
STEP 01

Read the city

At each landmark, a durable detail — the clock's numerals, a count of towers, the windows of Chagall — gives you a secret key.

STEP 02

Work the cipher

Set your decoder wheel to that key and decode the contact's intercepted message. Nothing is handed to you — you crack it.

STEP 03

Open the vault

Collect five letters that name the keepers — then use that name as the key to crack the final cipher and uncover the twist. Stuck? Your handler gives nudges, never answers.

Questions, answered

✦ ✦ ✦
Do I need an app or signal?

No. The game is a printed kit — a map, a decoder wheel and cipher cards. The only digital part is an optional QR “handler” for hints, which runs in any phone browser with no install.

How hard are the puzzles?

Clever but fair. You learn one simple cipher method, then apply it at each stop using clues you read off the real city. If you're ever stuck, your handler gives escalating tips — never the full answer.

How long and how far?

Two to three hours over a ~3 km loop, mostly flat with one short scenic hill at the finale. Go at your own pace and stop for coffee anytime.

Good for families?

Yes — great for ages ~10+ with an adult. A wholesome spy adventure with no scary or graphic content.

When can we play?

Any day, any time — it's self-guided. Daylight is best for reading the city and enjoying the views.

Refunds & reschedules?

Free reschedule up to 24 hours before your chosen start. Full terms at checkout.
