'Game of Thrones' Launches Challenge to Find Thrones Worldwide To celebrate the hit show's final season, <br />HBO launched a <br />"For the Throne" <br />campaign in <br />anticipation of <br />the release. The latest part of that campaign <br />asks fans to hunt for six Iron Thrones <br />hidden around the world. The network has revealed a <br />series of hour-long videos<br />to serve as clues. The clips were shot with a <br />360 degree camera, allowing hunters <br />to examine each throne's surroundings. As of now, the only "prize" is the <br />satisfaction of solving the challenge. Last month, HBO <br />partnered with the <br />American Red Cross to <br />urge blood donations <br />with their "Bleed for the <br />Throne" campaign. The final season of <br />'Game of Thrones' airs April 14.
