With millions of players logging in on a regular basis, there’s no doubt that World of Warcraft is one of the most popular games of all time. And for those super-fans who think they know everything about the long-running MMORPG, quiz site Sporcle is host to a new game where players must name each zone in the Eastern Kingdoms – with only five minutes to do so.

For the uninitiated, the Eastern Kingdoms in World of Warcraft consist of 33 unique locations that players will visit to further their character’s story, as well as complete the many side quests that the huge, open-world game has to offer. Naming them all would prove to be a challenge for even the most dedicated WoW fan, yet at the time of this article’s writing, the average user score sits at a respectable 77%.
