The goal is to move all cards to the eight foundations at the top.
Drag cards to move them between the ten tableau colummns at the bottom.
Click the stock (on the upper left) to deal a new card onto each tableau column.
When thirteen cards of the same suit from King all the way to Ace are together on a tableau column, they are automatically moved to the foundations.
Any time you expose a face-down card in a tableau column, that card is automatically turned face-up for you.
Tableau columns are built down by suit.
Empty spots on the tableau can be filled with any card.
