The Merchant’s Cipher

Decode the cipher that could bring down the Square Mile.

City of London2.5-3 hours

Centuries ago, a merchant in the City of London left a cipher hidden in the streets. Now someone is using it to move money and secrets - and your job is to crack the code first.

The Merchant’s Cipher takes you through the heart of the Square Mile: past the Bank of England, through Leadenhall Market, and along alleys that have seen centuries of trade and intrigue. The puzzles mix real history with a modern thriller plot.

You’ll need logic, teamwork, and a good eye for detail. The quest is aimed at 2-6 players and is best played on a weekday or weekend when the City is quieter and the architecture is easier to appreciate.

Whether you work in finance or just love a good puzzle in a historic setting, The Merchant’s Cipher will show you the City in a whole new light.
