After you buy the quest, receive an access code that you can use in the app. Begin your quest around Sighisoara's magnificent fortress by solving clues that will unlock stories, all on your smartphone. Along the way, discover fascinating stories of the towers, buildings, and people of Sighisoara. Follow a less crowded path around the old citadel, explore hidden passages, and discover amazing life stories of the ancient locals. The entire game will take you from 1.5 to 2 hours to complete, but there’s no time limit, you can finish it at your own pace. You won’t need a guide, just download the app, go to the starting point and you're ready to begin your city exploration 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 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.
