Jay Z has been closing the gap between the Internet and reality in an ongoing competition with the most impressive of prizes.

The '99 Problems’ rapper teamed up with Microsoft’s search engine Bing to create an international, and viral, scavenger hunt as part of the promotion for his new book ‘Decoded’. Contestants have been looking for pages of Jay Z's memoir, which have been strategically hidden in cities across the world.

Originally, winners of the contest were given the opportunity to attend his New Year’s Eve concert with Coldplay, but now he has upped the stakes and the prize has been extended to lifetime Jay Z concert passes.

The contest will close on November 20 and one winner will be picked from those who have been able to find every clue on the hunt.
