Daily Tower of Hanoi

A new puzzle every day at 00:00 UTC, the same for everyone. Solve it to tick the day off.

How it works

Each day’s puzzle is a shuffled position of six disks on three pegs. It is the same for everyone, it changes at 00:00 UTC, and it is always at least 32 moves from solved, so it is never an almost-finished board.

The calendar

Every day since 1 October 2026 is open, so you can catch up on days you missed; a solved day gets a star. Playing a solved day again is practice. Your results are kept on this device only, so clearing your browser data clears the stars.
