This variation of "Spiderette" is by Morehead and Mott-Smith.
One deck of cards
Object: Play all cards to the foundation.
Tableau: 7 piles.
Rank is built down. Cards can be any suit.
If a pile is empty, you can play any card.
You can pick up and play a group of cards in sequence. Cards must match the same suit.
Stock: Holds the 31 undealt cards.
Plays one card face up to each tableau pile.
Foundation: 4 piles.
You can only play a fully assembled ace-to-king sequence of cards. Cards must match the same suit.
Difference:
The tableau piles are dealt 3 cards each rather than in the 1-thru-7 style of Klondike.
With fewer cards buried, odds of winning should increase.
