Spider Solitaire Rules
You can play Spider Solitaire with two standard 52-card deck (no Jokers). This is called Four Suits Spider solitaire and it's the most difficult variation. You can only play One Suit Spider solitaire - also 104 cards but only one suit (e.g. the Spades) is used. There's also Two Suits Spider solitaire where two suits (e.g. Spades and Hearts) are used. Both are much simpler that Four Suits. After shuffling, a tableau is set up of a total of 54 cards, placed into ten columns. In each column, all of the cards are placed face down except for the last one which is upturned. The remaining cards are placed in the stock at the lower right of the layout (face down).
Your goal is to build stacks of card on the tableau forming descending suit sequences (from King to Ace). If a whole sequence is formed in one of the columns it is removed from the tableau completely. When all 104 cards are removed (as separate King to Ace sequences), you win the game.
You can move an exposed card to another column in the tableau if the movement creates a new continuous descending sequence (regardless of suit). You can also move a packed descending sequence of the same suit (they are highlighted for your convenience) as a group. That's why it's always better to form sequences of the same suit if possible. In case you already have some emptied columns on the tableau you can also move any exposed card or same-suit descending sequence there.
If you find yourself out of constructive moves you can click on the stock in the lower-right corner and deal a new card to every column on the tableau. But for you to be able to do this there must be no empty columns (you can move any card of sequence to fill an empty column).
