How to play

  • Only the top disc of a peg can be moved.
  • A disc may never be placed on a smaller one.
  • Move the whole stack from the left peg to the right one.
  • The minimum number of moves is two to the power of the number of discs, minus one.
  • A hint plays the next move of the perfect solution.

Tips

  • With an odd number of discs the first move goes to the target peg; with an even number, to the middle one.
  • The smallest disc moves every other turn, always in the same direction.
  • Between two moves of the smallest disc there is exactly one other legal move — make that one.
  • Do not plan the whole sequence: plan where the largest disc needs to go and repeat.
