The aim of Beleaguered Castle is to build all four suits up from ace to king.
First all aces are freed and put into four foundations.
Player is dealt remaining 48 cards into eight piles, 6 cards in each pile.
Foundations are built up by suit whereas tableaus are build down regardless of suit.
Once a card is played on a foundation, it can't be removed.
Only top card of a tableau is available for play to either another tableau or a foundation.
Empty tableau can be filled by any card.
The game is won after all cards are moved to their foundation piles.
