Spider runs fine on Windows 98, and is still addictive enough to be a serious time-waster.
Spider is a two-deck solitaire game.
Your object is to organize all 104 cards into suits by rank and clear the table. Complete rules and tips are included in the help file. Cool stuff All 12 face cards are unique, and their stories are explained in the help file. You can back up as many moves as you want, and if you get stuck, you can tell Spider to suggest a move. I haven't tested it on NT, but it should work there as well.
