You are the leader of the Hot ‘n' Cold Club, a group that uses its innate abilities to hone in on lost objects for distressed townsfolk. The stylus lets players lift and throw objects out of the way in 50 multi-room levels in both indoor and outdoor 3D environments. Real world physics make the search for hidden items more dynamic and fun as does the "Book Style" play that lets gamers turn the DS on its side. Three different online multiplayer modes-Hide ‘n Seek, Find the Most and Race-let gamers create their own levels by hiding objects within rooms and then sending those levels to a friend who must discover the hidden objects. These created rooms can also be shared with friends via local wireless multiplayer or the HotandColdHome.com online sharing community.
