Spider Solitaire is a column based solitaire card game.
In this game you can ignore the suit and your goal is to build down the columns from King to Ace. It's played with 2 decks of cards and the columns are removed when you've built down the columns from King to Ace. You can move either the top card in any column, or a fully packed series of cards. A fully packed series is a full series of cards that can not be picked up in the center. To make things a bit easier, I've dimmed the cards you can't move, so you should be able to pick out the cards your able to move pretty easily.
