Solve clues and unlock horror stories as you roam Paris' haunted streets. Each clue will lead you from one place to another, giving you precise directions so that you won't need a map, GPS, or guide.

After you purchase the quest, you'll receive an access code which you can use in the app. The quest will take you between 1-2 hours to complete, but there's no time limit which will allow you to have fun playing at your own pace. Throughout the quest, you will try to solve the curious case of Mona Lisa of the Seine, finding clues and encountering other spirits of the city.

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 ticket.

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.
