The Story

This next-level outdoor escape game takes you to various locations in the heart of Zwolle. You'll discover places in the city center you've never seen before.

In this two-hour experience, you and your team will ensure that the vanished cyberterrorist Neil Warren and his secret data are brought to light!

Meanwhile, you also have to make sure you don't get caught during the mission. You must proceed carefully, because otherwise…

De Klokkenluider is an outdoor escape room in Zwolle where you travel along a route of approximately 2.5 km through the historic city center. This game is perfect for friends, family, or a corporate outing looking to discover Zwolle in a completely different way.

You play independently via a hint system on your phone, without a game master on-site, at your own pace. Book De Klokkenluider at The Great Escape in Zwolle and combine the game with a terrace or dinner in the center if desired.

Language — This game is played in Dutch. Looking for a game in English? The Boobytrap can be played in English. (https://thegreatescape.nl/en/escaperooms/the-boobytrap)
