Spider solitaire rules

Goal: To remove all cards from the table, assembled in piles before.

Rules: The tableau piles need to be built down by rank from King to Ace. In games where more than one suit is used, only piles of cards of the same suit are considered completed. Only in-suit sequences of cards can be moved together. The empty pile can be filled by any card or sequence of cards. New cards can be dealt to the tableau when none of the piles are empty.

Difficulty: Easy - one suit, Medium - two suits, Difficult - four suits.
