The city game starts at The Mosaic Fountain. It will take you between 2 to 3 hours to complete and you can also explore at your own pace: pause the game and resume anytime from the location where you paused it. You will finish at White City Mark. As you solve challenges, the story unfolds and exact directions on your phone will guide you to the next location. Ready for an adventure? After your booking you will receive an email with instructions on how to download and play the game on your phone. You can play on your own, in a large group or in several smaller groups that compete against each other and meet at the final stop of the game. We recommend that each user purchases a ticket for an optimal experience, although several people can share a phone.
