Rules: Foundations are built in ascending order according to suit. The tableau piles are built in descending order according to suit. You can build only onto the topmost tableau card in each pile, but you can move multiple cards onto it. An empty space can only be filled with an available King.
Moving cards: To move the cards from one stack to another, use click-to-move. Click the card you want to move, then click the location to where you want to move it. You can also double click on a card to move it to a foundation stack. This makes it possible to use the game on devices that do not have a normal mouse. If your browser offers spatial navigation (such as Opera), you can use that to select the right card, but note that due to the number of positioned elements in close proximity to each other, the spatial navigation may have some trouble selecting the right cards. Note: Drag and drop will work, but the game has a tendency to freeze using this method--usually just as you are about to win. It is not recommended.
To start a new game: Click the "DEAL justly with me"* button or hit F5.
Options: You may select cardsets and card backs. Click the "Come and take CHOICE"** button to access these options.
