Klondike 10.2 is a Universal Carbon application and requires Mac OS X 10.2 or later, except for 10.2.2-10.2.4, which Klondike does not support due to font handling problems.
Klondike allows you to magnify or shrink the entire tableau, including the cards, by resizing the window.
Klondike will remember the enlarged window size only if your shareware registration was paid after June 30, 2001. A reduced price upgrade registration is available for users who registered prior to this date.
Start by selecting which solitaire game you wish to play. Choose the game by selecting Klondike, Canfield, Racing Demons, Golf or FreeCell from the Game menu. If you also wish to adjust other options, choose Preferences from the Klondike menu to display the dialog, use the popup list to select the game, then adjust the other options. Click OK when you have made your selection.
Press the Play or Replay button in the Scores sheet, or choose New Game or Replay from the File Menu. The Game window will be brought to the front and Klondike will deal the cards. If you pressed the Play button, Klondike will first shuffle the deck; Replay allows you to try again using the previous shuffle.
The dealing action is animated by default, so you see the cards moving to their positions. You can bypass the animation and jump directly to the game by pressing the Escape key (or typing Cmd-.), or turn it off by deselecting Deal Cards in the Animation pane of the Preferences window.
It is easy to play Klondike. You move cards between the deck, tableau, and foundations by dragging them with the mouse. Position the mouse pointer on the card you wish to move, press and hold the mouse button, and move the pointer to the destination pile. This will drag an image of the card along with the mouse pointer. When the outline of the moving card touches a legal destination, the destination will be highlighted. Release the mouse button when the highlight appears and the card you "picked up" will move to the destination.
If you don't see any legal moves, you can have Klondike highlight them for you by choosing Show Legal Moves from the Help menu, or typing Cmd-S.
To move an entire face-up pile of cards, position the mouse pointer on the highest card (i.e., the one deepest in the pile) and drag the pile. To move only part of the pile, drag the card you wish to move. Note: in Klondike, Canfield and Racing Demons this is not a legal move; you will need to hold down the Option key to drag part of the pile, and will be assessed a scoring penalty.
To turn up the top card in an uncovered, face-down pile, position the mouse pointer on it and click once. Clicking is also used to turn up the next card (or cards) in the deck.
As a shortcut, you may double-click on a card to move it to the destination. If there are multiple legal destinations, Klondike will try to pick the one which will lead to maximum score.
You can also use a contextual menu to move a card or pile, which allows you to specify the destination you desire for this move. To call up the contextual menu, position the mouse pointer on the card(s) you wish to move and click the secondary mouse button (or hold down the Control key while you click the mouse button).

If you wish to retract a move, choose Undo from the Edit menu. This will also restore the previous score (except for the elapsed time component). Up to 256 levels of Undo are available. Redo is available once an Undo has been performed.
The Enter key may be used as a shortcut for Undo.
If you wish to see the suits of the cards in the middle of a face-up pile, position the mouse pointer on any of those cards and press the mouse button without holding down the Option key. The pile will be expanded to fill the screen as long as you keep the button depressed.
When you start Klondike it automatically opens the Game window, which contains the layout; and displays the Scores sheet, which contains a dialog for setting the number of players and their names, choosing the next player, and viewing high scores. You may move and resize the Game window as you like, and Klondike will remember where you left it from one run to the next.
The Scores sheet is displayed when you start Klondike. Use the check boxes to designate the number of players in the game, and type their names in the adjacent edit text boxes. Select the next player using the radio buttons. To start the game, press the Play or Replay button. The sheet will go away and the game will begin.
The list of high scores can be reordered by clicking in the heading of the column you wish to determine the sort order.
Press the Reset button to clear the top 10 scores displayed in the right half of the Scores window. Holding down the Option key while clicking the Reset button will also clear the total game count.
You may also open a Help window by selecting Klondike Help from the Help Menu. This will display a list of available help topics. Clicking on a topic will display more detailed information. Click in the window's close box to close a Help window.
Choose About Klondike to display information about the version of Klondike you are running and the scalable font being used to draw the suit symbols.
The File menu contains three selections: New Game, Replay, and Import Scores....
When the Scores window has not been closed or hidden, choosing New Game or Replay to end a game brings the Scores window to the front. Press the Play or Replay button, or choose New Game or Replay once more, to start the next game.
During game play, shortcuts for these items are available on a contextual menu. Choosing New Game or Replay from the contextual menu will start another game in a single action.
Import Scores... allows you to import the option settings, total game count and high scores from an earlier version of the game or deck file.
The Edit menu allows you to Undo the last 256 moves you made in the game, or Redo any of those.
The Game menu allows you to select which solitaire game you wish to play. If you use this menu to choose a different game while playing a game, a confirmation dialog will appear.
The Help menu allows you to open the Klondike Help window or Show Legal Moves. The Klondike Help window offers explanations of Rules, Play, Scoring, or History (about this version of Klondike). You are now reading the text describing Play. Show Legal Moves will highlight legal moves available in the current layout of cards. While Klondike is showing the legal moves, you can bypass remaining moves by pressing the Escape key or the combination Cmd-.
