Build a tower of patience and precision in a focused offline puzzle experience. Move every disk from the starting post to a destination post while following one clear rule: a larger disk can never cover a smaller disk. Select a post and a destination, watch legal targets become clear, and learn the repeating pattern one move at a time. Choose from standard three-post challenges with 3 to 9 disks. Each challenge shows its theoretical minimum, so you can compare a careful solution with the mathematically shortest route. After completing the six-disk challenge, explore a four-post study with a verified reference value rather than an assumed universal formula. Open practice gives you room to experiment and provides a directional hint when you need a nudge. Undo and redo let you inspect your decisions, while restart makes another attempt immediate. The completion summary records moves, time, and your personal record for each challenge. Your unfinished arrangement, preferences, and records stay on the device. There are no accounts, social features, advertising, purchases, or network requirement. Use the guide to understand the hierarchy, then return to the board and make the next intentional move.
