Spider Solitaire: 4 Suits
Four-suit Spider is the full game: 104 cards, all four suits, no simplifications. Every rule matches the Spider you already know, but four card families compete for the same ten columns and clean in-suit runs stop happening by accident. In the published methodology-v2 cohort, players completed 20.6% of 843 eligible starts (95% CI 18.0–23.5%).

Why 4 suits is the expert game
At one suit every build is automatically in suit; at two you manage a boundary; at four, in-suit runs must be engineered several moves ahead. Column space is scarcer than it looks — four families need sorting room — and each ten-card stock deal punishes an untidy board four times harder than the one-suit game does.
The six, five and four of spades move together onto the seven of spades. The hidden card underneath flips face up.

Honest odds
Players completed 20.6% of 843 eligible four-suit starts in the published methodology-v2 cohort, with a 95% confidence interval of 18.0–23.5%. Current Random two-suit starts measured 17.6%, but the cohorts and player selection differ, so those figures cannot show that four suits causes a higher completion rate. Four suits remains the expert ruleset as an editorial judgment based on four-way suit conflicts, limited recovery space and the planning needed to preserve movable runs.

Four-suit strategy in brief
Everything from two-suit play applies, doubled: flips first, in-suit wherever possible, columns emptied deliberately. Add two habits — never deal the stock while an unprepared column will catch a random card, and watch where Aces and Kings land: Aces end runs (nothing stacks on them) and Kings start them (they stack on nothing), so their placement often decides the game.

Surviving 4 suits
No habit makes four suits easy. These make it winnable.
01Plan two moves out+
Play the board, not the move. Before each action, ask what it unblocks two moves out — at four suits, one-move thinking loses quietly and permanently.
02Break suit deliberately+
In-suit or know why not. Off-suit builds are for emergencies and for exposing flips; be sure which one you are doing.
03Guard empty columns+
Guard your empty columns. They are the only re-sorting space you will get; refill them only for a flip, a King, or a long in-suit run.
04Use undo to compare+
Undo is analysis, not weakness. Rewinding to test a different commitment is how four-suit lines are found — unlimited undo, no penalty.
05Prepare every column+
Count what the stock will do. Ten cards land on ten columns every deal; if three columns cannot absorb a random card, fix them before dealing.
06 · FAQ
4-suit Spider FAQ
Is 4-suit Spider the hardest solitaire?
It is among the hardest widely played variants as an editorial judgment based on four-way suit conflicts, limited recovery space and the planning required to preserve movable runs. Published player completion rates are separate, self-selected cohorts and are not a mathematical difficulty ranking.
Is 4-suit Spider ever winnable?
Yes. Deal solvability and player completion answer different questions. Players completed 20.6% of 843 eligible starts in the published methodology-v2 cohort, while the separate solver evidence estimates what may be possible with an ideal line of play.
What changes from 2 suits to 4?
No rules change at all — only the deck. Four card families instead of two means in-suit runs need planning instead of luck, and every column is contested by twice as many suits.
Should I learn on 4 suits directly?
We would start at two suits because it teaches the same-suit movement rule with fewer suit conflicts. Move to four suits when building and protecting clean runs feels deliberate rather than accidental.
How many cards and suits are in play?
104 cards — two full decks, all four suits. 54 start on the tableau across ten columns; 50 wait in the stock and arrive ten at a time.
Why do I keep losing early?
Usually the first stock deal hits an unprepared board. Before dealing, flip what you can, shorten mixed stacks, and try to hold an empty column — the deal is the moment a bad board becomes a dead one.
