Spider Solitaire – 4 Suits

Four suit Spider Solitaire is the full, unforgiving version of the game: two complete decks, all four suits, eight King-to-Ace sequences to assemble. The rules are identical to easier modes — build downward, move only single-suit runs as groups, deal from the stock when stuck — but with four suits in play, almost every placement blocks something. The question is never "is this move safe?" but "which damage can I best afford?"

Win rates drop sharply here, and that's the point. A won 4 suit game is a genuine achievement — the format has been compared to a puzzle you must partially solve blind, since a third of the deck starts face down and five stock deals are waiting to bury your work.

1. Plan before you touch a card. At the start of each position, read all ten columns and decide which one or two you're digging. Reactive play loses at 4 suits.
2. Treat off-suit builds as debt. Every mixed placement must eventually be unwound through an empty column. Take on debt only to reveal cards or prevent worse damage.
3. Fight for empty columns — then hold them. With four suits, an empty column is the only tool that untangles mixed stacks. Opening one is almost always worth sacrificing tempo elsewhere.
4. Complete runs opportunistically, not obsessively. Forcing a suit to completion too early can strand cards you needed as landing spots. Sometimes a finished run should wait a move or two.
5. Count the stock. Five deals of ten cards are coming. Before each one, tidy aggressively and note which columns are one flip from a reveal — attack those first after the deal lands.
6. Accept the losses. A meaningful share of 4 suit deals cannot be won by anyone. Judge yourself on decision quality across many games, not on any single result.

What's a good win rate at 4 suits?

Winning 10–20% without undo is strong play; experts using undo to explore lines reach considerably higher. Nobody wins consistently — some deals are simply dead.

Is it mostly luck?

Over many games, skill dominates: a strong player wins several times more often than a beginner on identical deals. Any single game, though, can be lost to the deal.

How should I prepare?

Win consistently at 2 suits first. The habits that are refinements there — in-suit discipline, guarding empty columns — are survival skills here.

Does using undo count as cheating?

Undo at this level is an analysis tool, like reading variations in chess: look ahead, back out, choose better. Playing without it is the purist path — both are legitimate.
