You are invited to discover the captive souls, the spirits and the mysterious skeletons of Cologne with an interactive city exploration app. You will be guided step-by-step to the cursed buildings where they carry out their eternal punishments while you learn all of their stories. Brace yourself and come explore Haunted Cologne, all with the help of your smartphone.

Each clue will lead you from one place to another, giving you exact directions, so you won’t need a map, a GPS or a guide. When you solve it and guess the answer, the secret story of that place is unlocked. Along the way, you’ll find horror stories that will give you the chills. Dare you go on this tour?

Complete the tour at your own pace as there's no time limit, though around two hours is normally enough. Pause the game at any time, and restart whenever you want from the last place you visited.

For larger groups, one person can purchase access for the entire group by selecting the number of people in the group. All group members will be able to play the city game on their smartphone. Alternatively, each person can purchase their own voucher.

You can play as a group and solve the clues together as you walk, or you can split into smaller groups/teams and compete against the others. Each person can also play on their own, separate from the group, and meet the group at the end.
