The Towers is a simple mathematical puzzle, which consists of three rods and a number of disks of different sizes which can slide on any rod, thus forming a conical shape. The rules are simple:

• Only one disk can be moved at a time.
• Each move consists of taking the upper disk from one of the rods and putting it on another one
• No larger disks may be placed on smaller disks.

Use 1, 2, 3 to move the disks. Alternatively, you can click the rod you want to select. Use the ESC key to abort your current turn.
