The legend of the Towers of Hanoi refers to a stack of 64 rings that when shifted the world will come to the end. Truth be told the sun would burn out long before anyone could finish the 18 sextillion moves required.
Only moving one piece at a time, and never stacking a bigger piece on a smaller piece, move the tower from the peg on the left to the peg on the right.
The tower can always be solved in 2n-1 moves where 'n' is the number of rings used. See how few moves you can use.
