Picture yourself the number one secret agent on earth. Now picture yourself on a mission to save captured zombies(?) from the menacing ghouls and trolls who have set riddles and traps along the way to deter you from success. They also brainwashed aliens, elves, Valkyrie and others to do their bidding.
That entire picture is just a small part of the world of trivia rescue. Prove that you are smarter and more covert than ghouls and trolls and rescue all captured zombies, defeat the trolls and save the fantasy land.
