Agnes is member of the ever-famous Klondike solitaire family. 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. The tableau piles are built the same as in Klondike, down by suit and in alternating colors. Ranks in this game wrap around, so a king or pile starting with a king can be played on an ace. Free tableau spaces can be filled by any card or pile starting with a card that's one less than the foundation seed. The other difference is how the deck is dealt- click the top of the deck to deal one card to each of the seven reserve piles. The top card of each reserve can be played on the foundations or the tableau, empty reserve slots will remain empty until the next deal. When the deck is down to two last cards, they're transferred to the normal wastepile and both are available to play.
Since the foundation starts of with one card and many cards are exposed for play at once, Agnes is a game that allows for much more skill and higher odds of winning than its more popular parent.
