Klondike

Klondike is probably the best known solitaire card 
game. One regular pack of 52 cards is used. Deal 
28 cards into 7 piles. The first pile at the left has one 
card, the second two, and so on, up to seven in the last
pile. The top card of each pile is face up; all the rest 
are face down. On the piles you may build in descending 
sequence, red on black or black on red. For example, 
on the 8 of spades you can place either the 7 of hearts 
or the 7 of diamonds. All the face up cards on a pile 
may be moved as a unit, and matched according to the 
bottom card. When you uncover a face down card on 
a pile, turn it face up. If one pile is entirely removed, 
you may put a king in the space. Each time you free an 
ace, move it to the Foundation, a row above the piles. 
On the Foundation you build up in suit and sequence. 
For example, the 2 of hearts may be placed on the Ace 
of hearts, the 3 of hearts may be placed over the 2 of 
hearts, and so on. To win the game, you have to build 
each Foundation up to the king. Once placed on the 
Foundation, a card cannot be moved anywhere else. 
From the rest of the pack, turn up cards one by one. 
Put cards that you cannot use into a waste pile. You can 
always use the top card of the waste pile. You may go 
through the pack only once. The game ends either when 
you win by building each Foundation up to the king, 
or when your moves reach a standstill.
