Cri's Spider

Free and no ads, just the game.

Spider solitaire uses two decks of cards and a tableau of ten stacks.
The hard level uses four suits, medium, two suits, easy, only one.

The Spiderette version of the game is a size-reduced version of Spider, using one deck and a tableau of eight stacks.

Cri's Spider let you to draw new cards even when there are empty stacks.
I simply don't like the dynamic of play of requiring to break some piles to fill empty stacks before drawing new cards.
