Spider Solitaire is played with two decks of cards. Depending on the difficulty level, the decks consist of either one, two, or four different suits.
The cards are arranged in ten columns. The top card in each column is face up, the rest are face down. The remaining cards are piled in the upper-right corner of the table.
To win, you must remove all the cards from the table by building columns organized in descending order, from king to ace. At intermediate and advanced levels, the cards must also match suit.
When you succeed in building a sequentially-ordered column, it flies off the table.
If you run out of moves, click the pile at the upper-right corner of the table and then deals a new row of cards.
You arent limited to moving just one card at a time. If a run of cards are all in the same suit, and arranged in numeric order, you can drag them around as if they were a single card.
