Sultan Solitaire Card Game

Just take a time-out, have a rest and try our new card play!
Sultan is quite an extraordinary and even exotic solitaire.
It is not very difficult and never demands from you brain-storming – just as, for example,
Diamond or, Up-and-Down. Its aim is to relax your mind and take your mind off any troubles.
Nevertheless, for the sake of success, you need to develop the strategy of your own, otherwise, you will loose.
Your task is to surround the King ('the Sultan') in the very middle of the tabletop with the Queens.
The cards are laid out following the suit, ascending, starting from the Ace.
You are welcome to select any of four difficulty levels – just for whetting your appetite.
