In Canfield Solitaire the goal is to move all the cards to the 4 foundation piles located in the upper right corner of the game.The foundation piles are built in suit from Ace to King.
You can use the middle 4 piles to hold the cards temporarily while you build up the cards in the foundation piles.
Build the middle piles up in descending order with alternating colors.
If you have used all the stock cards and cannot put all the cards on the foundation, then it's game over. Be warned this game is very difficult and the odds of winning are quite low, so perseverance is a must.
