The castle is quiet in the dead of night. All of the residents are fast asleep, oblivious of the nimble robber sneaking around the walls. Fortunately, the guardians of the legendary castle`s treasure don`t sleep - or, perhaps, they do... just for a moment? When a light-fingered thief catches two guards nodding off, he can steal the treasure that they`re supposed to guard. You have to uncover the right sleepyhead chips before the hunt for the precious treasure coins can begin in this memory game for crafty thieves.
