Uncle Roy All Around You (URAY) is a pervasive game[1] made by Blast Theory.
"[3] Players "on the street" set out on a journey to find a fictional character called Uncle Roy.
[4] Street players were presented with a map that they could pan around and subsequently mark their location upon.
The street players are asked if they are willing to "commit to help a stranger for the next year and if so, whether they are prepared to release their personal contact details".
Actors were used in some scenarios of the game and operators were some times required to deal with technical issues.
