An
interactive solution system, where you track every move by yourself,
is presented above. Choose the respective challenge from the popup
menu and then only click the "+" (or "-") to see the next (or
previous) single move of the entire slide or the respective disk at
the rotation spot. The "+" and "-" keys on your keyboard can be
useful for this as well. The counter shows you how many moves are
required for each challenge to be solved.
