A tableau layout is dealt the same as Klondike. A game of Spiderette can then begin.
The original Spiderette rules use all four suits from a single deck of playing cards, but the game is very difficult to win that way. Spiderette One Suit and Two Suit game variations exist that still use 52 cards, but only use the Spades in the one suit game and Spades and Hearts in the two suits game. Extra decks of cards are required to make up the numbers. This makes Spiderette considerably easier.
The object of the game is to build cards of descending suit sequence from King to Ace. e.g. K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A within the tableau columns. When such a sequence has been formed, it is automatically removed to one of the four foundations. When all 52 cards have been played to the foundations as four separate King to Ace sequences then the game is won.
All building is carried out on the tableau columns with the foundations not really participating in the game much. You may move any exposed card from the end of a tableau column to another tableau column if it creates a descending sequence (regardless of suit). e.g. 5 on 6 or 2 on 3. You may also move a packed descending sequence of cards as a group to another tableau column but only if they're of the same suit. e.g. 9, 8, 7 on 10 or 10. Therefore, you should try to pack cards of the same suit if you have a choice, otherwise you'll find the game blocks quickly. If you manage to create a complete descending sequence of cards from King to Ace of the same suit, e.g. K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A then it will be transferred to one of the foundations automatically. Empty tableau columns may be filled by any card or a packed descending suit sequence of cards. When no more constructive moves can be made on the tableau, touch the stock to deal another card to each of the tableau columns. You must fill all empty spaces in the tableau before you can deal cards from the stock, even if it means breaking up a sequence you have already packed.
