The goal of the game is to move the cards from the top columns to the four stacks
at the bottom, ordering them from ace to king.

When moving cards on the top columns you should follow these rules:

   - you can move a card on top of another card of different color and
     successive value, e.g.: you can move the three of spades on top of
     the four of diamonds.

   - a heap of cards can only be moved together, or you can move the topmost
     card.

   - you can only move kings to empty columns.

Clicking on the deck in the bottom left corner of the table will turn 3 cards
at once. You can pick the topmost card and move it either on the top columns
or on the stacks on the right, if possible.
