Treasure
A treasure is something "unknown" located on the earths surface.
A player with a Treasure Finder facility may locate treasures at intervals defined by the facility's level. The treasures are then displayed to all nearby players.
A treasure consists of 5 different pieces, one for each color. A player may only claim the one in his/her color. Tip: Team up with players of other colors and make a joint treasure hunt.
A treasure lasts for 24 hours before it disappears.
What the treasure contains is unknown until you claim it but a tip is that currently a good way to get Extenders is claiming treasures. (NOTE: Might change in the future.)
