Spider

An easy one-suit Spider with two decks. Put cards in descending order and clear eight complete runs from King to Ace.

1. This is one-suit Spider: 104 spade cards in ten columns. Your goal is to remove eight complete runs, each ordered King, Queen, Jack, 10 down to Ace.
2. Place a card or a descending run on a card one value higher. For example, move 8–7–6 onto a 9. A valid run can move together; a broken sequence cannot. Any available card or valid run can fill an empty column.
3. Face-down cards turn over automatically when uncovered. A full face-up King-to-Ace run at the bottom of a column is removed automatically and earns 13 points.
4. Click the stock to deal one new card to each of the ten columns. Every column must contain at least one card before you deal. There are five extra rows in the stock, and dealt cards do not have to fit the cards beneath them.
5. Click the first card of the run you want to move, then click the destination column. Clear all eight runs to win with 104 points. Undo lets you take back a move or a dealt row.
