Tower of Hanoi
A stack of disks will appear on the left peg.
Move the whole stack to the right peg.
Click a peg to pick up its top disk, then click another peg to place it there. Click the same peg again to put the disk back down.
Only one disk can be moved at a time, and a disk can never be placed on top of a smaller disk.
Try to finish in as few moves as possible.
