The True Genius line brings together brainteaser puzzles and links each design with an ancient civilization including China, Aztec, Rome, Greece and Egypt. The puzzles are finished in an antique style to look as though they might actually be artifacts from long ago. The True Genius line offers a wide variety of price points, difficulty levels and solve types - filling in the gaps of any store's puzzle section or standing alone as a comprehensive collection of brainteasers. To solve the Dendera, you will twist the top layer of the maze to open new pathways for both of the ball bearings to navigate from their respective start to finish paths through the constellations of the ancient night sky.
