The objective of the game is to shift the entire stack of disks from one rod to another rod following these three rules : Only one disk can be moved at a time. Only the uppermost disk from one stack can be moved on to the top of another stack or an empty rod. Larger disks cannot be placed on the top of smaller disks.

Why is the Tower of Hanoi problem important?

The Tower of Hanoi is a simple mathematical puzzle often employed for the assessment of problem-solving and in the evaluation of frontal lobe deficits. The task allows researchers to observe the participant's moves and problem-solving ability, which reflect the individual's ability to solve simple real-world problems.

Why is it called Towers of Hanoi?

The name 'Tower of Hanoi' refers to the capital city of Vietnam. When Lucas started to market the puzzle, French newspapers were full of reports about the siege that France had on the city of Hanoi against the Chinese.

What can we learn from Tower of Hanoi?

What is Tower of Hanoi in psychology?

The Tower of Hanoi is a classical puzzle applied in the psychology of problem solving and skill learning. In the standard wooden version, it consists of three vertical pegs and a variable number of disks, usually three to five, with increasing diameter.

Why is the Tower of Hanoi always solvable?

Since a Sierpinski triangle is connected, it is possible to move from any given legal position to any other, and so any Towers of Hanoi position is solvable.
