Spider type. 2 decks. No redeal.
Group all the cards in sets of 13 cards in descending sequence by alternate color from King to Ace and move such sets to the foundations.
The decks are separated. From one deck, four cards are dealt to each of eleven tableau piles, with alternating cards face-up and face-down (the bottom and third from the bottom cards are face-down). The remaining eight cards from that deck are combined with the other deck to form the talon.
Tableau piles are built down by alternate color, and any card or valid sequence of cards can be moved between tableau piles. Any valid card or sequence can fill empty piles.
The object is to group the cards in sets of 13 cards, from King to Ace in an alternating color sequence. Such groups can be moved to the foundations.
When there are no moves left, you can deal one card from the talon to each tableau pile. The game is won if all cards are grouped into sequences and moved to the foundations.
