How to play Spider solitaire
Spider uses two decks dealt into ten columns. You can place any card on a card one rank higher — a 7 on any 8 — and move a group of cards together when they are in order and all the same suit. When a column holds a complete run from King down to Ace in one suit, it moves off to the foundation automatically. Clear all eight runs to win. Any card or same-suit group can go into an empty column.
Dealing and controls
When you run out of moves, tap the deck at the top right to deal one new card onto every column — five deals in total. Fill any empty columns first, then deal. Drag cards with your mouse or finger, or tap a card to send it to the best spot. Hint shows a useful move, and undo works as many times as you like.
Tips
One suit is relaxed, two suits is a good challenge, and four suits is for experts. Build same-suit runs whenever you can, turn over face-down cards early, and treat empty columns as precious — they let you rearrange long runs. Your best time is saved for each mode.
