The Tower of Hanoi is a mathematical game or puzzle, which can also be used as a simple stacking toy for a young child. The pattern includes knit and crochet versions.

For the puzzle, a number of rings are arranged, on a post, in size order, to form a tower. There are two spare posts. The object of the game is to move all the pieces onto another post to form a new tower, with the pieces in the same order as the original.

Rules:

• Only one ring may be moved at a time.
• A ring can be moved onto any rod and placed on top of the pieces that are already there.
• No ring may be placed on top of a smaller ring.

Instructions are given for making seven rings but you can add more if you wish (as shown in the photos)

Some of the photos show the disks on specially made posts. The pattern suggests alternative ways to make the posts using easily available items.
