Westcliff is a solitaire card game which is played using a deck of 52 playing cards. It is a variation of Klondike that is fairly easy to win; one can win this game nine times out of ten.
First, ten columns of three cards each are dealt face down, then the top card of each column is turned face up.
The face-up cards are available for play either on the foundations or on each other on the tableau. The foundations are built up by suit from Ace to King. The tableau cards, as in Klondike, are built down by alternating color. A sequence of cards formed can be moved as a unit in part or altogether. Any face-down card once exposed is turned face up and a space that is exposed as a result of emptying a column can be filled with any card or sequence.
When there are no more moves to be made, the stock is dealt to the waste pile one at a time. Any card that cannot be built yet to the foundations or on the tableau is placed on the waste pile, the top card of which is available for play. The stock can only be dealt once.
The game is won when all cards are built onto the foundations, something that is very achievable in this game.
