Instead of thinking:
  1. "Where do I move the top (smallest) disc?" and then
  2. "How do I move everything else?"
try thinking
"Where do I move the bottom (largest) disc?" along with
"What must happen before I move the bottom disc?" and
"What must happen after I move the bottom disc?"

Oke,

These questions I can answer.

- Where do I move the bottom (largest disk) ?

To the last peg, which do not contain any disk then.

- What must happen before I can move the bottom disk ?

I have to move the disk which above that disk.

- What must happen after I move the bottom disk ?

All the other disk must be placed above that disk.


As I see it it seems a base case for the first and second disk that there are no disk anymore on that peg.
Then the last peg (3th) contains them all on the right order if you do all the steps according to the rules.
