Five secret contacts. A decoder wheel, cipher cards, and clues hidden in the streets themselves. Five letters that name the keepers — and unlock the vault. A rival agent walks the same trail. You have two to three hours to crack it all.
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.


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

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

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.
Each holds one piece of the ledger — and one Zurich landmark. Find them in order.
One ~3 km loop covers the banking heart, Europe's largest church clock, the Chagall windows, the twin-towered Grossmünster and the Roman birthplace of the city — ending on a panoramic hill. No spoilers — the puzzles are yours.

Prefer a platform you already use?
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.
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.
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.
