Rapper Jay-Z has hidden pages of his upcoming autobiography, Decoded, around the world.
Fans have been asked to answer questions on the hip hop mogul as part of an online competition to find the pages.
Online interactive maps will help fans to visit the cities that include Las Vegas, London and New York in order to find them.
The first participants to find a page will win a signed copy of the book, with all winners being eligible to win the big prize - a ticket to see Jay-Z and Coldplay in concert on New Year's Eve in Las Vegas.
Decoded will be released in stores from November 16.
