This is the Tower of Hanoi classical puzzle implementation in Python language
using pygame library.

The puzzle consists of three rods and a number of disks of different diameters,
which can slide onto any rod. The game starts with the disks stacked on one rod
in order of decreasing size, the smallest at the top, thus approximating
a conical shape.

The objective of the puzzle is to move the entire stack to the last rod,
obeying the following simple rules:
    - Only one disk may be moved at a time.
    - Each move consists of taking the upper disk from one of the stacks and
      placing it on top of another stack or an empty rod.
    - No disk may be placed on top of a disk that is smaller than it.

    and choose another tower. Select target tower by second mouse click.
    The disk will move onto the target tower, if the game’s rules do allow
    such move.

    Also you can use numeric keys (1, 2 or 3) for quick selecting the towers.
