🎮 Tower of Hanoi: How Close to the Minimum?

Move every disk from tower A to tower C, one at a time, and never let a larger disk sit on a smaller one. Four rounds of 3, 4, 5 and 6 disks share a single 180-second clock, each round paying in proportion to how close you come to the minimum number of moves (2ⁿ−1), and whatever time is left when the last round falls turns into bonus points. Once you see the rule, three disks take seven moves and six take sixty-three.
