Spider Solitaire

How to play

1. Two packs, 104 cards, all of one suit, or of two or four suits if you choose. The ten columns hold 54 cards: six in each of the first four and five in each of the other six, only the top one face up. The stock holds 50.
2. Any card goes on a card one rank higher, whatever its suit.
3. Several cards move together only as a run of one suit in descending order. An empty column takes any card or run.
4. Tap the stock to deal one face-up card onto every column, five deals a game. You cannot deal while a column is empty, unless fewer than ten cards are left on the table.
5. A complete one-suit run from king to ace goes to the foundations by itself, and a face-down card turns up by itself once the cards above it are gone.
6. Alone, you can undo any move as often as you like, a deal or a card turned up included, and your score goes back to what it was before it. In a race you can undo only moves that revealed nothing.

Points and winning

• You win by completing all eight runs before time runs out. Running out of time, or pressing Finish, is a loss.
• You start with 500 points, lose 1 for every move and every deal, and gain 100 for each completed run. Completing all eight adds a point for every second left. Playing alone, if you are stuck and press Finish with time left, you get a point for every second left, up to 100 for every run you have completed. In a race only completing all eight earns the bonus.
