Choose how many levels you want to play with and start. The rules are simple. 1-your goal is to remake the stack on the Right stand 2-you can only move one bar at a time 3-you can only place the bar if the base is of a higher number than the one you are placing Your moves are tracked and it tells you how many you can complete it in You can also press space to see the list of gods (people who have beaten the 10 tier level)
Tower of Hanoi is an old "game" that is supposed to end the world when a 64 tier game is finished by some monks. However that would take 18,446,744,073,709,552,000 moves to complete so I think we are safe for a while. You can play the original here: https://www.mathsisfun.com/games/towerofhanoi.html But that only goes to 8 tiers, and mine is 10 so I am clearly better.
