The treasure hunt can be built in the Game space of the Games room in a player-owned house. It requires 49 Construction to build and when built, it gives 800 experience. The player must have a hammer and a saw in their inventory to build it.
When activated, a treasure fairy will give each player a treasure stone, and will then hide somewhere in the house. The players must feel the stone to locate the fairy. Every time the stone is activated it will update the player from the last time it was touched, getting either colder or warmer. When hot the player is close to the fairy. Whoever finds the fairy first is the winner.
