The objective of Spider is to move all the cards from the ten card stacks at the top of the window with as few moves as possible.
The game:
The game is played with two decks of cards. When you start a new game, ten stacks of cards are laid out in a row, with the top card facing up. The remaining cards are placed in five stacks in the bottom right of the window. They are used when you want to lay new rows out.
Moving cards:
You can move cards from one row to another until you have a stack of cards of the same suit running from king down to ace. Once you have a complete stack of cards of the same suit, the cards are removed automatically.
Rules for moving cards:
You can move one card from the bottom of a stack to an empty stack.
You can move one card from the bottom of the stack onto a card of the next-highest value, irrespective of suit.
You can move a set of cards, all the same suit and in sequence, as though it was one card.
When you want a new row of cards, click the stack of cards in the bottom right corner. There must be at least one card in each stack before you can have a new row of cards.
Be careful not to remove too many cards. If you have rows without cards, you cannot continue.
