Your guide to Tower of Hanoi
A careful first move helps you understand the round. Move the complete stack of discs from the left tower to the right tower without placing a larger disc on a smaller one. Try the rule on the board, then read the next instruction. Choose three to eight discs. All discs begin on the left tower. Keep the goal in mind before your next move.
One puzzle with adjustable disc count from three to eight. Disc counts are settings, not separate game entries. Undo is available; refreshing restarts.
One thing to notice as you play
Keep the goal in view while choosing a move. An empty tower accepts any disc; an occupied tower accepts only a smaller disc than its top disc. Start a new round when you are ready to try again.
