I booked this event for my friends, who have birthdays around the end of March. There was 6 of us total.
It was exhilarating, working together to try and solve the clues. Every one of my friends had a great time and wanted to do it again. We plan on doing it again and buying all the tickets, so we're not joined by other folks we don't know. Communication is paramount in order to win.
I'd highly recommend this activity for some friends, a team-building event or a family.
