Tower of Hanoi

A very popular puzzle game. According to an Eastern legend, old monks in the great temple in the city of Benares move the 64 discs of the Tower of Hanoi. When they finish moving the entire tower, the world will end. Calculations suggest that moving 64 discs requires 18,446,744 trillion moves and would take at least 575 billion years. The fascinating Tower of Hanoi puzzle is now available as a free online Flash game. The more discs there are, the harder the puzzle is and the more moves it takes to solve it.
