Spider is an extremely popular column based solitaire card game. The game is played with two decks of cards, and you can ignore the suits when building columns. From each column you can only move the top card, or a fully packed series of cards. A fully packed series is a run of cards in order that can't be grabbed from it's middle. Don't worry, I dim any cards you aren't allowed to move to make things easier for you.
Your goal is to build a column of cards from King to Ace. Once you have a column like this, it's removed from the game. You need to remove all the cards from the 2 decks in order to win. If you get stuck, you can deal more cards from the deck by clicking on it at the bottom of the game screen.
