Penguin Solitaire uses 52 cards. 49 cards are dealt into 7 tableau piles (7 cards per pile). Seven cells (reserves) are placed above the tableau piles. Four foundation piles are placed to the right of tableaus. The first card dealt to the first tableau pile is the "penguin". This will be the starter card of the foundation. The three other cards of the same rank are moved to the foundation piles during the deal.
The object of the game
To free the "penguin", and to build the foundations up in suit, wrapping from King to Ace as necessary.
The top cards of tableau piles and cards from cells are available to play. You may build tableau piles down in suit. One card or group of cards in the proper sequence can be moved from pile to pile. When one of the tableaus is empty it may be filled only by a card (or a group headed by a card) one rank below the starter card. The top card of any tableau pile can also be moved to any cell. Each cell may contain only one card. Cards in the cells can be moved to the foundation piles or back to the tableau piles, if possible.
