Hey r/solitaire,
I grew up on XP Solitaire and missed it. And the more I thought about it, the more it bugged me that there's no good way to play it anymore - you can't buy it, you can't legally download it, and current Windows ships Microsoft Solitaire Collection, which isn't really the same game. It feels wrong to let something that iconic just fade out, so I spent the last few weeks rebuilding it in the browser.
It's live at xp-solitaire.com — free, no ads, no signup, no app install.
The goal was preservation, not reinterpretation. Same card art (both the photographic XP backs and the older Susan-Kare-era ones, with the animated robot and castle), same rules and scoring, same win cascade. A few small additions for modern screens — configurable display scaling, a fullscreen button, an optional auto-finish button - but nothing that changes how the game plays.
If anyone gives it a try, I'd love to hear where it diverges from the original - parity is the goal, so bug reports and "you got X wrong" notes are very welcome.
