Igra Diskova

## Description

_Igra Diskova_ is an adaptation of _Towers of Hanoi_ where disks from left
most stick need to be moved to the right most stick. The easier variant also
allows to move disks from left to either of the two remaining empty sticks.
The game contains 8 discs which vary in diameter, starting with largest on the
bottom and smallest on top, and 3 sticks. When moving between sticks, disc can
be carried and placed only on top of disc with larger diameter.
