Explore the Dublin buried beneath your feet, a Dublin of English invaders, run with an iron fist by the Catholic Church and built by the Vikings. Uncover their stories by playing a quest with your friends, significant other, or family.

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.

After you book the quest, you’ll receive instructions on how to play by e-mail. The tour will take you up to two hours to complete, but there’s no time limit, so go at your own pace. You won't need a guide, just download the app, go to the starting point and be ready to begin the adventure.

If you are a large group, 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 smartphones. 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 other groups. Each person can also play on their own, separate from the group and meet the group at the end.
