Spider Solitaire strategy
Better Spider play is mostly sequencing: uncover hidden cards, keep an empty column when you can, delay the stock, and prefer same-suit builds. On SpiderImp, fewer moves rank above faster time.
What should you do first?
Expose face-down cards as soon as it is safe. Every hidden card you skip is information you do not have when the next deal lands. Turnovers often matter more than making a pretty mixed stack.
How do you use empty columns?
Treat an empty column as workspace, not a dump. Park a run, unpack a mixed column, then refill the hole before you deal. If Deal is disabled, you still have an empty—see the dealing rule.
When should you deal?
Deal when you have no useful tableau move, not as soon as the button lights up. A deal adds ten cards and can bury the empty-column plan you were one move from finishing.
Same-suit vs mixed builds
Single cards may sit on any suit of the next rank, but only same-suit sequences move as a group. Temporary mixed builds are tools; convert them back to same-suit as soon as you can, especially in 2-suit and 4-suit.
How do modes change the plan?
1 suit: almost every stack is movable—focus on turnovers and empty columns. 2 suits: protect same-suit chains; Daily Challenge is a good practice length. 4 suits: expect more blocked piles; Undo and Hint are fair helpers, not cheats. Compare modes: 1 vs 2 vs 4 suits.
How should you think about the score?
SpiderImp ranks moves, then time. A slightly slower win with fewer moves beats a rushed win. Details: scoring.
