3 Decks.   Easy (85%).  Mostly Skill.



To move two decks (or 8 suits) of cards to the foundations, to move the other deck (or 4 suits) of cards into 13 piles of 4 cards of the same rank.



8 foundation piles (top left) - build up in suit from Ace to King.


7 tableau piles (below foundations) - build down in suit.  Move groups of cards if they are in sequence down in suit.  Fill spaces with Kings or groups of cards headed by a King.   At the start of the game 7 cards are dealt to each pile, alternating face up and face down.


13 reserve piles (on right) - Cards may be played on other cards of the same rank.  At most 4 cards are allowed in any pile.  Empty piles may be filled by any card.  At the start of the game 4 cards are dealt face up to each pile.


stock (top left, face down) - turn over 1 card at a time, by clicking.  No redeals.


waste (next to stock) - top card available for play on the foundations or tableau.






In the reserve piles, cards may be played on other cards of the same rank.  For example, if the top card of a pile is a Three, another Three can be played on top of it.  The object is to move the cards so that there are 13 piles of 4 cards of the same rank, that is, one pile of 4 Kings, one pile of 4 Queens, and so on.


8 suits of cards are played to the foundations.  Note that you do not necessarily have to play two piles of each suit to the foundations, any 8 suits out of the 12 suits in 3 decks may be played to the foundations based on the suits of the starting Aces.  The remaining 4 suits are played to the 13 reserve piles.   It is important to keep track of which suits are needed in the reserve piles.
