Spider Solitaire is the computer version of the two-deck patience game, credited here to Microsoft and dated 1998. The rules predate computers entirely: you build descending runs from king to ace and, once a run is complete in a single suit, it leaves the table.

Microsoft had a specific reason for shipping card games with its systems. Bundled solitaire titles were not only entertainment, they were mouse training. Dragging a card from one column to another teaches click, hold, move and release without a single line of documentation, and Spider does it with more depth than the simpler patience variants.

1998 fits a moment when a colour screen and a mouse were assumed on every office machine. The catalogue records a top-down view, which for a card game simply means the whole table laid out in one window, no scrolling and no perspective involved.

The defining feature of Spider is that difficulty is set by suit count. With one suit it is a few minutes of tidying; with four it becomes a genuinely demanding puzzle where move order matters and an empty column is a resource you spend carefully.

Bundled card games have an unusual audience profile: they were played on machines where no other game was installed or even permitted. Solitaire therefore found players who never considered themselves gamers. Technically it was undemanding software that ran in a window, closed instantly and needed neither a sound card nor acceleration, which is precisely how it reached office desks.
