After purchasing your quest, you will receive a code which grants you access to the quest in the app (the app is free to download). Along the way, you'll pass by the House of the Devil, you'll find out about the organ traffickers at the Bucharest Post Office, and you'll discover many other strange places and stories of the city. The quest can be played at any hour, but it is recommended that you try it at night for the authentic haunted experience. It will take you between 1 -2 hours to complete, but there’s no time limit which means you can finish it at your own pace. Each clue will lead you from one place to another, providing you with exact directions, so you won’t need a map or GPS. When you get the correct answer, the secret story of that place is unlocked, making you your own guide for this adventure. 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.
