Dordrecht riddle tour: Solve a historical mystery

You receive access via email after booking and start whenever you like. Hints keep you moving if you get stuck. Suitable for ages 12 and up, playable solo or with others on a single phone.

The experience

You arrive in Dordrecht with a free afternoon and a smartphone. Instead of wandering, you unlock a riddle game that turns the city into a puzzle. The game sends you to six stops (each one a real building or square with genuine historical weight), and at each one you observe your surroundings carefully to answer a question. The Aardapelmarkt shows you picturesque houses and the Woolweaver's Docks; the Wijnstraat holds the Huis De Onbeschaamde, named for a naked statue carved into its facade; the Stadhuis and Grote Kerk anchor the city's political and spiritual past. The riddles are not trivia: they ask you to notice details, read plaques, look at the architecture itself.

The mystery threading through it all is real. In 1672, the De Witt brothers were assassinated in Dordrecht: a turning point in Dutch history. But a document has surfaced claiming a different version of events. The riddles guide you through the evidence, and by the time you finish, you have solved it yourself. If you get stuck, hints appear to keep you moving. There is no dead end. You can play alone on your phone or hand it to a friend and solve it together, both of you watching the same screen.

After you book, an email arrives with a link and access code. You start whenever you want: no fixed time, no guide waiting, no crowds. The whole game takes one to two hours depending on how long you linger at each stop. Children under 12 can play with adult help, and strollers work fine on Dordrecht's streets.
