🕷️ Spider Solitaire

Objective: Remove all 104 cards by completing eight same-suit sequences from King down to Ace.

The tableau: The game begins with 54 cards in ten columns. Only the top card of each column is face-up. Moving cards can uncover and automatically turn over the next face-down card.

Building: Place any face-up card on a card exactly one rank higher, regardless of suit. For example, any 9 can be placed on any 10.

Moving sequences: A single face-up card can move by itself. A group can move together only when every card in the group is in descending order and all cards share the same suit.

Empty columns: Any single card or valid same-suit sequence can move into an empty column. Empty columns are especially useful for reorganizing mixed-suit stacks.

Stock: The remaining 50 cards are dealt in five rows of ten. Tap the stock to add one face-up card to every column. You cannot deal while any tableau column is empty.

Completed runs: A full same-suit King-to-Ace sequence at the bottom of a column is removed automatically. Complete all eight runs to win.

Difficulty:

• 1 Suit: All cards use Spades, making sequence building much easier
• 2 Suits: Spades and Hearts are mixed across the deck
• 4 Suits: All four suits are used, creating the full challenge

Scoring: You begin with 500 points. Each move or stock deal subtracts 1 point, and each completed King-to-Ace run adds 100 points. Undo also costs 1 point.

Tips:

• Prioritize moves that uncover face-down cards
• Build same-suit sequences whenever possible so they can move together later
• Protect empty columns until you can use them to reorganize a difficult stack
• Before dealing a new row, make every useful move available on the current board
