Office Spider Solitaire - Spider solitaire with one, two or four suits
The difficulty here is determined by the number of suits: one, two or four. The more suits, the more difficult it is to complete Spider Solitaire to the end. You need to clear the table by lining up rows of the same suit from king to ace. At the beginning there are ten piles on the table: four of six cards and six of five, with only the top card exposed.
The card can be placed on any card one higher, even of a different suit: the seven of spades will fall on the eight of hearts. But you can transfer several cards at once only if they are in a row and of the same suit. Any card fits into the empty column. If you want a version with an average number of suits at once, there is Spider Solitaire 2 Suits.
