Spider Solitaire (2 suits)

Two-suit Spider Solitaire deals 104 cards in spades and hearts, four decks of each, into ten columns. Any card goes on one a rank higher, but only a run of one suit moves together, so you build in mixed colours when you must and sort each suit out as columns open up. It is the classic Spider: hard enough to think about, gentle enough to win often.

The rules are classic Spider: five more deals of ten wait in the stock, and a new deal needs every column filled. Clear all eight runs from king down to ace to win. Every deal is checked by a solver before you see it, so it can be won, and undo and hints are unlimited; play into a dead end and the table offers to rewind to the nearest position that still wins. The daily deal is always two suits, the same for everyone. Want it easier or harder? Try one suit or four.
