Solitaire: Also called Klondike.

Rules and basics:

The object

Build four stacks of cards, one for each suit, in ascending order, from ace to king.

The table

Solitaire is played with a single deck of 52 cards. The game begins with 28 cards arranged into seven columns. The first column contains one card, the second has two cards, and so on. The top card in each column is face up, the rest are face down.

Four Home stacks are positioned at the upper-right corner. This is where you build the piles needed to win.

How to play

Each Home stack must start with an ace. If you don't have any, you'll have to move cards between columns until you uncover one.

You can't move cards between columns at random, however. Columns must be built in descending order, from king to ace. So you can place a 10 on a jack, but not on a 3.

As an added twist, cards in columns must also alternate red and black.

You aren't limited to moving single cards. You can also move sequentially organized runs of cards between columns. Just click the deepest card in the run and drag them all to another column.

If you run out of moves, you'll have to draw more cards by clicking the deck in the upper-left corner. If the deck runs out, click its outline on the table to reshuffle it.

You can move a card to the Home stack either by dragging it or by double-clicking it.

Scoring

Under Standard scoring, you receive five points for moving a card from the deck to a column, and 10 points for each card added to a Home stack.

If a game takes more than 30 seconds, you also receive bonus points based on the time it takes to finish. The bonus formula: 700,000 divided by total game time in seconds. Thus, the highest possible Standard score is 24,113!
