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.
• | 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. |
• | 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. |
