The Manchester, UK-based game is a high-tech version of hide and seek where players can interact online and on the street and work together to search for an elusive "Uncle Roy".
The companies behind "Uncle Roy All Round" say the game changes the way the players interact with the city, which sounds enlightening and all that but we have a sinking suspicion that this hunt for the phantom Roy will turh out a little more like "Waiting for Godot".
