Hanoi is a simple terminal version of the known classical game Tower of Hanoi, written in Bash.

During the game, the user can move left and right, pick disks and drop them in other stacks.

The aim is to move all the disks from the ORIGIN pile to the DESTINATION pile, in as little moves as possible

If I correctly remember the minimum number of moves required to get all the disks from one tower to another, 10 layers is going to be a slog.

    The minimum number of moves required to solve a Tower of Hanoi puzzle is 2**n − 1, where n is the number of disks. 1023 for 10 disks, 5011 for 9 disks (updated max disks in the game). Recursion to the max.

    More moves for less disks?

    Yup, this is fat finger mathematics. The correct number is 511, somehow zero got in the way.

    I might be just tired, but it took me a stupidly long second to get that minimum number of moves formula - not to nitpick, but isn’t that exp. usually written as 2^n - 1 ?

    Didn't know it had a name but that makes sense... I remember playing a minigame puzzle like that as a kid in KOTOR
