This game is a bit different, but once you have mastered the idea, can be fun.
The idea of the game is to use up the thirteen cards in the stock pile (top left), and complete the four foundations (top right).
The game begins with one card in the first foundation. This sets the pattern for the other three foundations, which must be started with the other cards of the same value. Once started, each foundation is built on using the next card of the same suit (i.e. in ascending order). When the foundation has a King on top, this can be covered by the Ace of the suit.
The four working columns (bottom right) can be built up in decreasing order, with each card of alternate color. Whenever one of the working columns becomes empty, then it can be filled by a card from the either the stock pile or the discard pile.
Cards in the deck (bottom left) can be turned over onto the discard pile three at the time (next to the deck), and when appropriate, the cards in the discard pile may be moved to the foundations or the working piles.
When all the cards in the deck have been moved to discard pile, they can be turned back over (to the deck again) by clicking where the deck was.
If you go right though the deck without being able to place a card, then you cannot win, and will have to start again.
As a hint, if a working column becomes empty, then it is usually better to place a card from the stock pile in it, rather than a card from the deck.
