CS596 Project

1) Design and implement a program to play the solitaire card game klondike. A user of the program should not be allowed to make illegal moves. Optional features of the program include, but are not limited to providing the user with hints, allowing backtracking and allowing the user to save games. The rules for klondike are given below. You will be graded on your design, program and documentation.

2) (Optional) Design a program to play spider. What parts of the design for klondike can be reused in spider? How would your klondike design change if you were designing a program to play both spider and klondike? The rules for spider are given below.

## How solitaire games are played[1]

All solitaire games are played with one or more full packs of 52 cards each. A pack of cards contains four suits, each identified by its symbol, or pip: spades, hearts , diamonds and clubs. Clubs and spades are black, hearts and diamonds are red. Each suit contains thirteen cards: ace (A), king (K), queen (Q), jack (J), 10, 9, 8, 7, 6, 5, 4, 3 and 2. Most solitaire games proceed in the following way:

Some or all of the cards are distributed face up in some distinctive array, forming the tableau. The tableau together with any other cards dealt at the outset are often called the layout.

The initial array may be changed by building. Certain cards of the tableau are immediately available for play, while others may not be played until certain blocking cards are removed.

The first objective is to release and play into position certain cards called foundations. The ultimate objective is to build up the whole pack onto the foundations, and if that can be done the game is won.

If not all of the pack is laid out in the tableau at the beginning, the remainder of the pack forms the stock, from which additional cards are brought into play according to the rules of the game. Cards from the stock which can find no place in the tableau or on foundations are laid face up in a separate pile called the talon or waste pile.

In some games, the layout includes a special packet of cards called the stock; any remainder of the pack not dealt out at the beginning is then called the hand.

In many games a vacancy in the tableau created by the removal of cards elsewhere, called a space, is of capital value in manipulating the tableau.

The rank of cards in solitaire games is: K (high), Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A.

### Klondike

CARDS - One pack.

TABLEAU - 28 cards in 7 piles. The first pile, one card; the second, two cards; and so on up to seven. The top card of each pile is face up; all others are face down.

Deal from left to right by rows; first row: one card face up and six face down; second row: a card face up on the second pile, and one face down on each other pile; and so on.

FOUNDATIONS - The four aces. Each ace, as it becomes available, must be played to a row above the tableau. Foundations are built up in suit and sequence.

OBJECT - To get the four suits built up onto the foundations up to the kings.

BUILDING - Any movable card (from tableau, stock or talon) may be placed only on a card next-higher in rank than the bottom card of the unit, and of opposite color. If more than one card is face up on a tableau pile, all such cards must be moved as a unit. Example: (diamond)3, (club)4, (heart)5 may be moved as a unit onto (spade)6 or (club)6. When there is no face-up card left on a pile, the next card below is turned face up and becomes available.

SPACES - May be filled only by kings.

STOCK - The rest of the pack after the tableau is dealt forms the stock. Turn up cards from the top of the stock one by one and build each if able. The stock may be run through only once. (Variant. Go through the stock by threes without limit.)

TALON - Place unusable stock cards face up on a talon pile. The uncovered card of the talon is always available for play, provided the next card of the stack has not been turned.

### Spider

CARDS - Two packs shuffled together.

TABLEAU - Ten piles of five cards each, dealt by rows. The first four cards of each pile are dealt face down, the top cards face up. All play is made on the tableau; there are no foundations and no talon.

BUILDING - The top card of each pile may be moved, together with all below it which follow it in ascending suit and sequence. A sequence of available cards may be broken at any point and some left behind. Example: Pile from top down shows (heart)4, (heart)5, (heart)6, (club)7; the first one, two or three cards may be moved as a unit, but 7 may not be moved until the covering three cards are removed.
When all face-up cards on a pile are removed, the next card below is turned face up and becomes available.
A moveable unit of cards may be placed either in a space or on a card of rank next-higher than the bottom card of the unit, regardless of color or suit. Example: (heart)J may be moved onto any one of the four queens. A king can be only moved into a space.

OBJECT - To assemble thirteen cards of a suit, in ascending sequence from top down (ace to king) on top of a pile. Whenever a suit is so assembled, lift it off and discard it from the game. The solitaire is won if all eight suits are so cast out.

SPACES - May be filled with any moveable unit.

STOCK - When all possible or desired moves on the tableau come to a standstill, deal another row of ten cards face up on the tableau piles. Before such a deal may be made, all spaces in the tableau must be filled. The final deal comprises only four cards, which are placed on the first four piles from the left. (Variant. The four extra cards are added face down to these piles in laying out the tableau.)
