Simple Spider Solitaire is a Palm version of one of the more popular two-deck card games around, which you may have played in Windows XP or Vista.
The main aim of Simple Spider Solitaire is to remove all of the cards from the tableau. The cards are dealt into 10 piles, face down apart from the top card. You must then assemble piles running down by rank or in-suit sequence in order to clear the tableau. You can use spaces but they can only be filled with groups of 13 cards in sequence headed by a King.
Never having played this one before, I found Simple Spider Solitaire quite confusing to start with. Luckily, there is a comprehensive help system, and Simple Spider Solitaire will even show you the cards that can be moved.
What I loved about Simple Spider Solitaire is the sheer range of options in it. Not only can you customize the theme of the deck, but you can also pick from a huge array of game settings, from game style options to which tools are available from the toolbar. There's also a statistics menu, where you can view basic stats about your performance over time.
It might take you a while to get used to the rules, but overall Simple Spider Solitaire makes for an enjoyable and well presented Solitaire game.
