Challenge scroll

Challenge scrolls are logical problems posed to the player by an NPC. They appear in Medium and Hard clues in Treasure Trails and have two steps to it: first the player has to find the right NPC to speak to (when they get a cryptic or anagram clue), and then they have to solve the riddle, to advance along their trail. Thus, challenge scrolls don't count as a regular clue. To complete the scroll, view the question on the scroll, then speak to the NPC which gave it to provide the answer. When the correct answer is provided the challenge is complete, and the player will receive either the next clue, or the reward. It is also possible able to obtain more than one challenge scroll by asking the NPC players got it from with a full inventory. Every time players talk to the NPC, another appears on the ground that they can pick up. However, if they already have one in their inventory or bank, they cannot pick another one up.

List of solutions
The following is a list of all known challenge scrolls and their solutions. The riddles are usually fairly simple, but sometimes call on trivial facts such as 'How many animals are in the Ardougne Zoo?' This list will allow players to bypass counting animals.
