Klondike solitaire

Klondike is the solitaire most people picture: seven columns of cards, stacked downwards in alternating colours, with four piles to fill from ace to king. Turn over cards from the stock when you run out of moves. Some versions here deal three cards at a time, which is noticeably harder than dealing one. Start with Klondike Solitaire or Klondike Solitaire Paradise.
