‘The Go Game’ is a high-tech urban adventure game where teams of 5 adults are given cell phones with large screens, digital cameras and a mission that is constantly updated via hidden hints and the wireless web. Contestant teams, many corporate, many just groups of friends, set out in a major city competing to find clues, complete tasks and venture into the bizarre. ‘Go’ is a board game taken to the next level, where the ‘board’ is San Francisco, the ‘rules’ are reality, and you are the ‘pieces.’
