It is very simple. You need phone/tablet with an internet connection. Laptop will work as well, although running around the city with a laptop might be considered strange. Then gather a team of up to 5 people. Every team needs a leader, so someone is accountable for bad results and praised for good. Team lead needs to sign up and create an account. Once this is done browse through available mazes and make a purchase. That's it, you now have access to the maze whenever you are ready. To make life easier, you can share your team's login details with team members. This allows them to participate and read the clues with you. Although, you can always consolidate power to one device and gather your group around you for a better team bonding experience!
