Free tableau spaces can be filled by any card or pile starting with a card that's one less than the foundation seed.
Ranks in this game wrap around, so a king or pile starting with a king can be played on an ace. The tableau piles are built the same as in Klondike, down by suit and in alternating colors.
The first difference between Agnes and Klondike is that the top of the deck is dealt to the first foundation the rest of the foundations are built up by suit starting with this card's rank. However, its rules are changed to make the odds of winning the game easier. Agnes is member of the ever-famous Klondike solitaire family.
