From the manufacturer:
Historical figures, events and cultures have all left us clues to secrets, treasures and myths. Passed on by a chosen few who have succeeded in masking the secrets, it is now time to follow the clues and attempt to uncover their mysteries. Galileo, Newton and Einstein: three historical visionaries known for revolutionary mathematical, mechanical, astronomical and scientific discoveries. But each used previously discovered theories, tools and visions in order to advance their own. These scientists may simply have left us clues on which to build. Or could it be that their allegiance and associations are the real formula and part of an even bigger meaning. Welcome to a journey through 7 unique puzzles. Venture the trail and the clues and possibly solve the mystery. The Equation is the 2nd puzzle in this line of 7 where you are challenged to arrange the puzzle pieces within the boundaries to construct a base. The completed puzzle then becomes part of a series of clues needed to solve the overall puzzle. Once complete, the Equation base combines with a section of the DaVinci Code Puzzle to reveal a clue to the next part of the mystery.
