HBO has taken their marketing to the next level for Game of Thrones Season 8. The network went ahead and hid six actual Iron Thrones replicas around the world and teased their locations on social media. The first tease started last week, and so far, five out of the six have been located by fans who have followed the clues. HBO has yet to comment on the matter, but they probably underestimated hardcore Game of Thrones fans.

It didn't take long for fans to discover the first Iron Throne in HBO's Game of Thrones quest. The first picture showed a replica of the throne surrounded by some mossy rocks in a forest. Alex Bowring and Tom Maullin-Sapey of Oxford were the first to locate the Iron Throne of the Forest in Puzzlewood, which is located in Gloucestershire, U.K. The two were rewarded with a special crown and bragging rights. The throne remains and fans can now go take pictures on it if they can locate it.

In addition to the Puzzlewood location, the Game of Thrones quest has brought fans to Bjorkliden, Sweden (Throne of the North); Atienza, Spain (The Throne of Joy); and Beberibe, Brazil (Throne of Valyria). The fifth Iron Throne, The Throne of Ice, was just discovered in Babcock Creek in Tumbler Ridge, British Columbia, Canada, by Kevin and Birgit Sharman. As for the sixth and final Iron Throne, that is a mystery at this time. However, it probably won't be for long as Game of Thrones fans from all of over the world are on the hunt.

HBO has yet to announce the sixth Iron Throne clues, but it is expected to do so shortly. The promotional campaign is unique and immersive, giving fans something else to look forward to while they all wait for Game of Thrones Season 8 to premiere in April. We're getting close and this global scavenger hunt has been a cool way to get the hardcore fans united in something other than looking for how the hit HBO series will finally end and who will be alive to claim the real Iron Throne.

That's not all that HBO cooked up to promote Game of Thrones Season 8. Fans can head over to For the Throne to figure out what they are willing to do for the Throne. Fans are able to go on the physical quests, or they can bleed for the throne. And while that sounds pretty weird, it's actually a clever way of getting people to donate blood to the Red Cross. Finally, hardcore fans can check out some one-of-a-kind props from the show that have been customized by fans. Game of Thrones is certainly going big for the beginning of the end.
