A Puzzle box is an item received from a Treasure Trail. Players need to complete the puzzle in order to receive their next clue. There are Four possible pictures on the puzzle box, being a Castle, a Tree, a Troll, and a Bridge with a fifth, depicting a gnome glider, seen during Monkey Madness. They are similar to the real worldSlider Puzzle. Occasionally, players will need to solve Puzzle boxes in order to complete a hard or elite treasure trail. One must also be solved during the Monkey Madnessquest.
Puzzle boxes contain a scrambled image that players must work to unscramble by clicking on tiles to move them to an empty space. Once the puzzle box is completed, players need to talk to the NPC who gave them puzzle to receive the next clue or the reward. In elite trails, solving the puzzle automatically presents the player with the next clue or the reward upon closing the window. As with all puzzles, logging out will reset the puzzle, even if it has already been completed. If players want their puzzle reshuffled, they should destroy the box (not clue) and ask the NPC for another.
Some of the newer puzzle boxes have a 'hint' in the bottom left hand corner that shows the player the image of the completed puzzle.
Players could get a puzzle box from Ali Tist in central Falador, south of the west bank, but they are different from the normal ones, as they don't have a picture puzzle. They are used for the Void Stares Back quest. When the solve option is selected, the player tries a few times, but gives up.
