The most fiendish form of Solitaire I have found. It really requires thinking and planning, unlike Klondike. I suspect Windows doesn't include it because then NO ONE would get any work done. It is almost as addicting as E2

Like most solitaires you play black on red or a color on itself,in descending numerical order. The object is to get a string from King down to Ace all of the same suit,at which point you can discard the string. Winning obviously means all cards get discarded.

The kicker is that when you have finished all moves for one turn, you have to slap down ten new cards across the array, totally obliterating all your careful strategies.

You can play this demon game at http://www.idiotsdelight.net/spider.html. The game is easier if you use the options to lower the number of cards in the stack and to "allow unfilled spaces."
