There are no foundations. Instead, you build downwards on the seven piles on the table. You don't have to follow suit, but when you do, you may move entire suits in one move. When you have a complete suit from ace to king, you can double-click it to remove it.

This is one of the two single-deck variations of Spider. This variations is the one I've seen in other computer solitaires. The deal is like Klondike, in 7 piles, and all the gameplay is just like Spider.
This is a pretty hard game to win. If you want an easier kind of Spider, try Itsy Bitsy Spider.
>Topic<Rules
The cards are dealt in seven piles (the table), with the top card open and the others closed. The cards are dealt as in Klondike, with different number of cards in each pile (7-6-5-4-3-2-1). The rest of the cards form the hand.
On the table, you may build in falling sequences. Sequences in one suit may be moved as a unit.
Any card may be played on a free space.
When you click on the hand, one card is delt to each pile.
Once you have a full suit, from ace to king in one suit, you may double-click it to remove it.

I don't want to comment on strategy here, since I find Spiderette so hard that I can't claim to know how to solve it.

I learned this game from other computer card games. It is not in any of my card game books. Thus, it seems as if Spiderette is less generally accepted than Spider, with Itsy Bitsy Spider being the "small Spider" of some areas.
