The goal is to build 4 sequences from King to Ace and then move them to the foundation. You can place a card on another card if the card is smaller than the other card by one. Also, you can move several cards at once, if the top card is smaller than the other card by one and the cards are in sequence. You can place a card or sequence of cards on an empty space. You can press the pile of cards on top and then more cards will be added to the columns. Use the mouse to double-click or drag the cards. You can move a built sequence to the foundation by double-clicking or dragging the King.
