Tower of Hanoi

Stack all the discs on the first peg in order of size, with the largest disc on the bottom and the smallest on top.

Move discs one at a time, taking only the topmost disc from any peg for each move.

Place a moved disc on an empty peg or on top of a larger disc, never on top of a smaller one.

Plan your sequence of moves to gradually shift the smaller discs out of the way while relocating larger ones.

Repeat this process, moving discs among the three pegs, until the full stack is rebuilt in its original size order.

The puzzle is complete once every disc has been transferred to a different peg from where it started, in the same stacked order.
